Garnet - January
If you are
loyal, devoted and energetic, then perhaps the garnet is your stone.
Red garnets were believed to promote sincerity, stop hemorrhaging or
other loss of blood, cure inflammatory diseases, and cure anger and
discord. And if you engraved a well-formed lion image upon it, it
will protect and preserve honors and health, cure the wearer of all
disease, bring him honors, and guard him from all perils in
traveling. All in all, quite a worthwhile stone.
A hard, durable,
often very brilliant stone, available in many colors of greens,
reds, yellows and oranges, it affords versatility and opportunity
for adorning jewelry.
Garnets are also
a deceptive stone. Some red shades appear like rubies, some greens
like emeralds, and some yellows for topaz.
Garnets can be
found in every color except blue. It is best known in a deep red
variety, sometimes with a brownish cast, but it is commonly found in
orangish brown shades, and brilliant wine red shades as well. Other
colors include orange, red purple, violet, and pink. A
non-transparent variety, grossularite, has a jadelike appearance and
may be mistaken for jade when cut for cabochons or carved. There is
also a star garnet found in the U.S. that is a reddish to purple
variety, which displays a faint four-rayed or six-rayed
star.
Amethyst - February
Amethyst, a
transparent purple variety of quartz, is one of the most popular of
the colored stones. In contemporary times, recognized as the
of February, it was once believed to bring peace of mind
to the wearer. It was also believed to prevent the wearer from
getting drunk, and if the circle of the sun or moon was engraved
thereon, it was believed to prevent death from poison.
Amethyst is
available in shades from light to dark purple, it is relatively
hard, fairly brilliant, and overall a good versatile wearable stone.
Amethyst is available in good supply even in large sizes. Note that
large sizes with deep color are becoming scarcer. Amethyst is
probably one of the most beautiful stones available at a moderate
price, although one must be careful because "fine" amethyst is being
produced synthetically. Synthetic amethyst exhibits color zoning
often looking like chevrons.
Amethyst may
fade from heat and strong sunshine. Guard your amethyst from these
conditions and it will retain its color indefinitely.
Aquamarine or Bloodstone
March
To dream of
aquamarine signifies the making of new friends and to wear
aquamarine earrings brings love and affection. Aquamarine, a
universal symbol of youth, hope, and health, blesses those born in
March. Prior to the 15th century it was thought to be the
for those born in October.
Aquamarine is a
member of the beryl family, which includes emerald, but aquamarine
is less brittle and more durable than emerald. Aquamarine ranges in
color from light blue to bluish green to deep blue, which is the
most valuable and desirable color. Do not purchase a shallow cut
stone, since the color will become paler as dirt accumulates on the
back. Aquamarine is a very wearable gem, clear and brilliant, and,
unlike emerald, is available with excellent clarity even in very
large sizes. Larger size aquamarines are becoming scarcer, therefore
more valuable. Long considered a beautiful and moderately priced
gem, aquamarine has moved into the "expensive" classification for
stones in larger sizes with a good deep blue color.
One must be
careful not to mistake blue topaz for aquamarine. While topaz is an
equally beautiful gem, it is usually much less expensive. Topaz is
usually treated to obtain its desirable color. For those that cannot
afford an aquamarine, blue topaz is an excellent alternative, as
long as it is properly presented and properly priced.
Diamond
- April
The diamond has
been one of the most coveted gems in history. Uncut diamonds adorned
the suits of armor of the great knights. Cut diamonds have adorned
crowns of kings and queens throughout the ages. Today the diamond is
internationally recognized as a symbol of love and betrothal and is
the recipient of increasing interest as a source of investment.
The diamond has
been credited with many magical powers. At one time it was
considered the emblem of fearlessness and invincibility. It was
believed that the mere possession of a diamond would endow the
wearer with superior strength, bravery, and courage. It is also
believed to drive away the devil and all spirits of the
night.
In the 1500's it
was believed to enhance the love of a husband for his wife. In the
Talmud a gem believed to be a diamond, from its description, was
worn by the high rabbi and served to prove innocence or guilt. If
the accused was guilty, the stone grew dim, if innocent, the stone
shone more brilliantly than ever.
The Hindus
classed diamonds according to four castes. The Brahmin diamond,
colorless, gave power, friends, riches and good luck. The Kshatriya
diamond, brown/champagne, prevented old age. The Vaisya, color of
the "kodali flower", brought success, and the Sudra, a diamond with
the sheen of a polished blade-probably gray or black-brought all
types of good fortune. Red and yellow diamonds were exclusively
royal gems, for kings alone.
Diamonds have
been associated with almost everything from producing sleepwalking
to producing invincibility and spiritual ecstasy. Even sexual power
has been strongly attributed to the diamond. There is one catch to
all the associated powers; one must find the diamond "naturally" in
order to experience its magic, for it loses its power if acquired by
purchase. However, when offered as a pledge of love or friendship,
its powers may return, hence the use in engagement rings given in
love.
Diamond have
been found to occur naturally in almost every color and shade, blue,
red, green, yellow, lavender, pink, gunmetal blue, coffee brown, and
black. The color may be intense or very pale. These are very
expensive because they are very rare, some more than others are. The
most common fancy colors are shades of yellow, very intense, bright
yellow called "canary", orange and brown. Among the most rare and
most valuable are the reds and blues, and the least valuable are the
black diamond.
Emerald - May
Emeralds have
been used for ornamentation since 4000 BC. The vibrant greens of
Emeralds have long been associated with fertility and rebirth. Many
cultures have used Emerald as treatment for eye diseases, epilepsy
and poisoning. Emeralds have been held under the tongue as a way of
foretelling the future. Emeralds were dedicated to the Goddess Venus
and were considered an aid in revealing the truthfulness of one's
lover. But their incomparable beauty is reason enough for owning the
gem.
The first stones
were mined in Cleopatra's Mines in the Egyptian desert near the Red
Sea. These mines were abandoned after being worked for thousands of
years. They were rediscovered in 1818 and today the Egyptian Emerald
lodes are small and dark stones.
The top Emerald
producing countries are Columbia, Zambia, Brazil and Zimbabwe.
Emerald deposits are typically found in metamorphic rocks with no
particular surface indications for possible mining locations. Mining
for the 6-sided Emerald crystal is primarily done by
hand.
Emeralds are
part of the Beryl mineral family, along with Aquamarine, Golden
Beryl, Goshenite, Bixbite and Morganite. The name for Emerald is
taken from the Greek smaragdos, meaning green stone. Inclusions are
generally accepted in Emeralds. These inclusions help to separate
natural from synthetic Emeralds and possibly the country of
origin.
Although
Emeralds have a hardness of 8, they still must be treated with care
to prevent chipping. Emerald jewelry should never be ultrasonically
cleaned nor steam cleaned. Since most Emeralds exhibit some type of
visible inclusion, the degree of clarity is not as important as with
other type of Beryl. Most natural Emeralds have tiny surface breaks
that fill with air and are visible to the eye. For centuries,
organic oils and resins have been used to prevent these surface
breaks from being visible. Since these oils have a tendency to dry
out over time, manmade substances, including epoxies, are now being
used to lessen the surface fissures. The best way to care for
emerald jewelry is to use warm, soapy water and a soft
brush.
The top color
for Emerald is a deep, rich green. Emeralds are available in a range
of green tones, including yellowish green, bluish green and pure
green. Emeralds that are transparent in the top color command the
highest prices.
Pearl - June
The pearl, pure
and fair to the eye, has been recognized since the earliest times as
the emblem of modesty, chastity, and purity. There are two types of
pearls available today. The natural or Oriental pearl-the real
"genuine pearl"-is considered a precious gem, since they are
relatively rare in nice sizes. Most commonly found today is the
cultured pearl from pearl farms. Pearls are produced by oysters in
saltwater and by mussels in freshwater lakes and rivers.
Quality and
value are determined by:
- Freedom from
skin blemishes (blisters, pimples, or spots)
- Roundness-the
more perfectly round the better
- Luster-the
higher the luster the better (known as Orient by some
gemologists)
- Tint-rose-tinted are highly desirable as are white and
cream
- Size-natural
pearls are sold by weight measured in "grains" Cultured pearls are
sold by millimeters. The larger the pearl, the greater the cost.
For example, 71/2 mm to 8 mm is considered large but 9 mm to 10mm
is considered very large both in size and price. The price jumps
upward rapidly with each millimeter once you pass 8 mm.
When all of
these factors come together in a set or stand of pearls, acquiring
them may be excessively costly, but you will have the finest
available. If any quality factor is lessened, the savings can be
significant.
Pearls should be
handled with care. It is best to keep them in a separate pouch and
to exercise some caution when wearing to avoid contact with certain
substances such as vinegar (when making a salad), ammonia, inks, and
certain perfumes, since these can spot the pearls surface. Also
frequent applications of hair spray while wearing pearls will coat
them and make them very dull, but this coating can be cleaned by
washing with nail polish remover.
Pearls are
available in many colors including gray, black, pink, and blue.
Unfortunately, the colors are often produced using surface dying
techniques. A qualified gemologist should be able to detect dyed
pearls.
Ruby - July
Prized through
the ages, even by kings, as the "gem of gems...surpassing all other
precious stones in virtue," and today's for July, ruby is
the red variety of the mineral corundum. Historically, it has been
symbolic of love and passion, considered to be an aid to firm
friendship, and believed to ensure beauty. Its color ranges from
purplish or bluish red to a yellowish red. The finest color is a
vivid, almost pure spectral red with a very faint undertone of blue,
as seen in Burmese rubies, which are considered the finest. The ruby
is a brilliant stone and is very hard, durable, and wearable. Ruby
make an unusually fine choice for any piece of jewelry.
Translucent
varieties of ruby are also seen, and one variety exhibits a six-ray
star effect when cut as a cabochon. This variety is called star ruby
and is one of natures most beautiful and interesting gifts to
man.
Peridot - August
Today
for August, peridot, was also a favorite of the ancients. This
lovely transparent yellowish green to deep chartreuse stone was
quite a powerful gem. It was considered an aid to friendship and was
also believed to free the mind of envious thoughts. Because of the
yellowish green color, it was also believed to cure or prevent
diseases of the liver and dropsy. And, if that were not enough, if
peridot was worn on the left arm it would protect the wearer from
the evil eye. It is also popular today, but probably more for its
depth of green color than its professed powers. While not
particularly brilliant, the richness of its color is exceptional.
Peridot comes in shades of yellowish green to darker, purer green
colors. Peridot is widely available in small sizes but larger sizes
are becoming scarce, so prices for larger sizes are now fairly high
for good quality material. Some caution should also be exercised
when wearing peridot. It is not a very hard stone and may scratch
easily. Some stones may look like peridot-green sapphire and green
tourmaline-and may be mistaken for peridot or be
misrepresented.

Sapphire - September
The sapphire is
the symbol of the heavens, bestower of innocence, truth, good
health, and preserver of chastity. Sapphire is part of the variety
corundum. While it is known best for the blue variety it is
available in nature in almost every color. The red variety of
corundum is the ruby. The sapphire's hardness, brilliance, and
availability in so many beautiful colors make it an important and
versatile gemstone.
The finest
sapphires are considered to be the blue variety, specifically those
from Burma and Kashmir, which are the closest to the pure spectral
blue. Many of the current sapphires used in jewelry today are very
dark but can be treated to lighten the color for better beauty.
Sapphires from Ceylon are mare pastel looking than the deep rich
color of Burmese and Kashmir sapphires.
Blue sapphires
are also mined in Australia, Tanzania, Brazil, Africa, and the U.S.
in Montana and North Carolina. Blue sapphires are found in a
translucent variety that may show a six-rayed star effect when cut
in cabochon style. These are known as star sapphires and there are
numerous synthetic star sapphires on the market. Fancy sapphires are
becoming increasingly popular in colors of yellow, pink and green.
Opal - October
The opal has
suffered from an unfortunate reputation as being an evil stone and
bearing ill omen. There are several explanations for the ominous
superstitions surrounding this wonderful gem, but the evil
associations have never been merited and probably resulted from a
careless reading of Sir Walter Scott's Anne of Geierstein.
Among the
ancients, opal was a symbol of fidelity and assurance, and in later
history, it became strongly associated with religious emotion and
prayer. It was believed to have strong therapeutic value for
diseases of the eye, and when worn as an amulet, it would make the
wearer immune from all such diseases as well as increase the powers
of the eyes and the mind. Many believed that to the extent the
colors of red and green were seen, the therapeutic powers of the
stones with those colors-red and green-the powers were also to be
enjoyed by the wearer, the power to stop bleeding (ruby) and the
power to cure kidney disease (emerald). The black opal was
particularly highly prized as the luck stone of anyone lucky enough
to own one.
This stone,
whose brilliant colors resemble the colors of the fall, is unique
among the gems, displaying an array of very brilliant miniature
rainbow effects, all mixed up together. This is opal's most
distinctive characteristic. This effect is created by opal's
formation process, which is very different from that of other gems.
Opal is composed of hydrated silica spheres. The mini rainbows seen
in most opals result from light interference created by these
spheres. The arrangement of the spheres, which vary in size and
pattern, is responsible for the different colors seen.
Opal is usually
cut flat or in cabochon since there is no additional brilliance to
be captured by a good faceting job. Color is everything. The more
brilliant the color, the more valuable the gem. This is probably
truer of opal than any other stone. The more beautiful the stone and
its color, the more it will cost.
The finest of
all opals is the black opal. Black opals are usually a deep gray or
grayish black with flashes of incredibly brilliant color dancing
around within and about the stone as it is turned. One must be
careful when purchasing a black opal; to ensure it is not a doublet
or triplet, a stone composed of two or three pieces of stone glued
together. There are many such doublet and triplets in the market
because of the black opal's rarity, beauty, and extremely high cost.
A natural black opal the size of a lima bean could cost as much as
$50,000 in today's market. The black opal doublet and triplet
provides an affordable alternative to the one who loves them but can
not afford them. Beware, this also presents an opportunity for
misrepresentation that can be very costly to the consumer.
Generally
speaking, the purity of color, absence of dead spots, called
trueness, flawlessness, and intensity or brilliance of color are the
primary variables affecting value. Those opals with an abundance of
red are usually the most expensive, and those strong in blue and
green are equally beautiful but not as rare, so their prices are
somewhat less. Some opals are very transparent and are classified as
"jelly", "semi-jelly", or "water" opals.
One word of
caution must be offered. Opals require special care because some
tend to dry out and crack. Avoid exposure to anything that is
potentially drying. Bathing an opal occasionally in olive oil or
coating it with olive oil when not in use will help preserve it. But
do not soak any opal in oil because soaking some opals for only a
few hours can cause them to lose some or nearly all of their fire.
Topaz - November
True topaz, the
symbol of love and affection, aid to sweetness of disposition and
on November, is one of natures most wonderful and least
known families. The true topaz is rarely seen in jewelry stores.
Most people know only the quartz (citrine) topaz, or glass. In the
past almost any yellow stone was called topaz.
Topaz occurs not
only in the transparent yellow, yellow brown, orange brown, and
pinky brown, but also in a very light to medium red, very light to
light blue, very light green, light greenish yellow, and colorless.
Topaz is a hard, brilliant stone with a fine color range.
Blue topaz has
become popular in recent years and most of it is treated for color.
Blue topaz closely resembles the finest aquamarine and offers a very
attractive affordable alternative to aquamarine. Some of the fine,
deeper blue treated topazes have been found to be radioactive, and
according to the Nuclear Regulatory Commission, may be injurious to
the wearer. The true topaz family offers a variety of color options
in lovely, clear, brilliant, and durable stones.
Turquoise - December
A for
December, and ranking highest among all the opaque stones,
turquoise, the "Turkish stone" is highly prized throughout Asia and
Africa, not only for its particular hue of blue, a robins-egg blue
or sky blue, but more importantly for its prophylactic and
therapeutic qualities. The Arabs consider it a lucky stone and have
great confidence in its benevolent action. Used in rings, earrings,
necklaces, head ornaments and amulets, it protects the wearer from
poison, reptile bites, eye diseases and the evil eye. It was also
believed capable of warning of impending death by changing color.
Also, the drinking water in which turquoise has been dipped or
washed was believed to cure bladder ailments. Buddhists revere the
turquoise because it is associated with the legend in which a
turquoise enabled Budda to destroy a monster. Even today, turquoise
is considered a symbol of courage, success, and love. It has long
been associated with American Indian jewelry and art.
Turquoise is an
opaque, light to dark blue or blue green stone. The finest color is
an intense blue, with poorer qualities tending toward yellowish
green. The famous Persian turquoise, which can be a very pleasing
and intense blue, is considered a very rare and valuable gem.
All turquoises
are susceptible to aging and may turn greenish or possibly darker
with age. Care must be taken when wearing turquoise, both to avoid
contact with soap, grease, and other materials that may discolor it,
and protect it from abuse, since turquoise scratches fairly easily.
Exercise caution
when buying turquoise. This is a frequently simulated gem. Very fine
adulterated stones and reconstructed stones saturate the market, as
does synthetic turquoise. |
