Pearl is the only gemstone to come from a living creature and not from under the earth’s surface. Pearls require no cutting or polishing like gemstones do. Almost any shelled mollusk can, by natural processes, produce some kind of “pearl” when an irritating microscopic object becomes trapped within its mantle folds, but the great majority of these “pearls” are not valued as gemstones.

Long known as the “Queen of Gems,” pearls possess a history and allure far beyond what today’s wearer may recognize. Throughout much of recorded history, a natural pearl necklace comprised of matched spheres was a treasure of almost incomparable value, in fact the most expensive jewelry in the world. Now we see pearls almost as accessories, relatively inexpensive decorations to accompany more costly gemstones.

Gem quality pearls are very rare in nature and come from certain types of clams. Many hundreds of pearl oysters or mussels must be gathered and opened, and thus killed, to find even one wild pearl; for many centuries, this was the only way pearls were obtained, and why pearls fetched such extraordinary prices in the past. Cultured pearls are formed in pearl farms, using human intervention as well as natural processes.

Natural pearls are nearly 100% calcium carbonate and conchiolin. It is thought that natural pearls form under a set of accidental conditions when a microscopic intruder or parasite enters a bivalve mollusk and settles inside the shell. The mollusk, irritated by the intruder, forms a pearl sac of external mantle tissue cells and secretes the calcium carbonate and conchiolin to cover the irritant. This secretion process is repeated many times, thus producing a pearl. Natural pearls come in many shapes, with perfectly round ones being comparatively rare.

Cultured pearls are the response of the shell to a tissue implant. A tiny piece of mantle tissue (called a graft) from a donor shell is transplanted into a recipient shell, causing a pearl sac to form into which the tissue precipitates calcium carbonate. There are a number of methods for producing cultured pearls: using freshwater or seawater shells, transplanting the graft into the mantle or into the gonad, and adding a spherical bead as a nucleus. Most saltwater cultured pearls are grown with beads. Trade names of cultured pearls are Akoya, white or golden South sea, and black Tahitian. Most beadless cultured pearls are mantle-grown in freshwater shells in China, and are known as freshwater cultured pearls.

Cultured pearls can be distinguished from natural pearls by X-ray examination. Nucleated cultured pearls are often ‘preformed’ as they tend to follow the shape of the implanted shell bead nucleus. After a bead is inserted into the oyster, it secretes a few layers of nacre around the bead; the resulting cultured pearl can then be harvested in as few as six months.

When a cultured pearl with a bead nucleus is X-rayed, it reveals a different structure to that of a natural pearl (see diagram). A beaded cultured pearl shows a solid center with no concentric growth rings, whereas a natural pearl shows a series of concentric growth rings. A beadless cultured pearl (whether of freshwater or saltwater origin) may show growth rings, but also a complex central cavity, witness of the first precipitation of the young pearl sac.

Fine quality natural pearls are very rare jewels. Their values are determined similarly to those of other precious gems, according to size, shape, color, quality of surface, orient and luster.

Single natural pearls are often sold as collectors’ items, or set as centerpieces in unique jewelry. Very few matched strands of natural pearls exist, and those that do often sell for hundreds of thousands of dollars. In 1917, jeweler Pierre Cartier purchased the Fifth Avenue mansion that is now the New York Cartier store in exchange for a matched double strand of natural pearls Cartier had been collecting for years; at the time, it was valued at $1 million USD.

Besides being soft, pearls are easily damaged by chemicals like perfume, vinegar and lemon juice. Heat can turn pearls brown or dry them out and make them crack. Dry air can also damage pearls. When taking off a pearl ring, grasp the shank, or metal part, rather than the pearl. This will prevent the pearl from loosening and coming into contact with skin oil on your hand.

For cleaning special care should be taken. Only use jewelry cleaners labeled as safe for pearls. Never use an ultrasonic cleaner. Never steam-clean pearls. Never use (or expose pearls) to dish or wash detergents, bleaches, powdered cleansers, baking soda, or ammonia-based cleaners (like Windex). Never use toothbrushes, scouring pads or abrasive materials to clean pearls. Take your pearls off when applying cosmetics, hair spray, and perfume, or when showering or swimming.

Pearls symbolize love, purity, chastity, romance and eternity. Pearls are a favorite gem for wedding jewelry. It has been a favorite for people of many cultures. An old Arab legend tells that pearls were created when dew drops filled with moonlight fell into the ocean and were swallowed by oysters. Freshwater cultured pearls are a beautiful inexpensive gift for any June birthdays.

May’s Birthstone – Emerald – Green Beryl

In a set of poems released by Tiffany & Co. in 1870, each month is matched with a gemstone. The poem for May reads:

Emerald Ring 14 Karat White Gold Heart Shape 4.7 Carats R61618

Emerald Ring 14 Karat White Gold Heart Shape 4.7 Carats R61618

“Who first beholds the light of day
In spring’s sweet flowery month of May
And wears an emerald all her life
Shall be a loved and happy wife.”

Emerald is a rich forest green color gemstone. It is a member of the Beryl mineral family along with siblings Aquamarine and Morganite. Emerald is also a member of the four precious gemstones along with Ruby, Sapphire and Diamond.

Emerald‘s chemical composition includes the elements Beryllium (Be), Aluminum (Al), Silicon (Si) and Oxygen (O). The dark green color of Emerald is created by trace element Chromium (Cr), and sometimes Vanadium (V). Green Beryl is only considered an Emerald if it has a strong green to dark green color. The lighter green Beryls are simply called “Green Beryl.” This is very similar to Ruby Vs. Pink Sapphire and Rubellite Vs. Pink Tourmaline.

Emerald (and other beryls) are quite hard at about 7.5 to 8 on the Mohs scale. The emerald is often clouded by inclusions. They are not classified as faults but show the difference between natural and synthetic stone. Almost all natural emeralds are treated with oil to fill in and diminish the appearance of these inclusions and fissures. Due to these inclusions and fissures, emeralds can be rather brittle or fragile. A little extra care is needed when using emeralds in jewelry.

Unlike Diamonds, Emeralds’ clarity is judged by the naked unaided eye because of these inherent inclusions. Diamonds are generally judged with a 10x loupe for their clarity.

Columbia is currently the largest producer of fine Emerald gemstones. Brazil and Zambia are also very large producers of fine Emeralds. Brazilian emeralds are prized for their excellent clarity and slightly yellowish green color, while Zambian emeralds are desired for their slightly bluish green color, which is similar to that of Colombia’s ’emerald-green’ emeralds.

The Gachala Emerald is one of the largest gem emeralds in the world, at 858 carats (171.6 g). This stone was found in 1967 at La Vega de San Juan mine in Gachalá, Colombia. It is housed at the National Museum of Natural History of the Smithsonian Institution in Washington, D.C. One of the world’s largest emeralds is the so-called ‘Mogul Emerald’. It dates from 1695, weighs 217.80 carats, and is some 10cm tall. One side of it is inscribed with prayer texts, and there are magnificent floral engravings on the other side. This legendary emerald was auctioned by Christie’s of London to an unidentified buyer for 2.2 million dollars on September 28th, 2001.The New York Museum of Natural History, exhibits a cup made of pure emerald, which belonged to the Emperor Jehangir, next to the ‘Patricia’, one of the largest Colombian emerald crystals, which weighs 632 carats.The Viennese treasury contains a vase, 4.5 inches (12 cm) high, with a weight of 2205 carats, which was cut from a single emerald crystal.

Both hydrothermal and flux-growth synthetics have been produced, and a method has been developed for producing an emerald overgrowth on colorless beryl. Hydrothermal synthetic emeralds have been attributed to IG Farben, Nacken, Tairus, and others. The first satisfactory commercial product appeared on the market in the 1960s. These stones were initially sold under the names “Emerita” and “Symeralds”, and they were grown as a thin layer of emerald on top of natural colorless beryl stones.The largest producer of hydrothermal emeralds today is Tairus in Russia, which has succeeded in synthesizing emeralds with chemical composition similar to emeralds in alkaline deposits in Colombia, and whose products are thus known as “Colombian Created Emeralds” or “Tairus Created Emeralds”.

Emerald is thought to bring good luck and enhance well-being. The magnificent green of the emerald is a color which conveys harmony, love of nature, life and of the springtime. It has also, for centuries, been the color of beauty and of constant love. In ancient Rome, green was the color of Venus, the goddess of beauty and love. Today, this color still occupies a special position in many cultures and religions. Emerald is also thought to be a stone of wisdom, enhancing memory and increasing mental clarity. Emerald is the anniversary gemstone for commemorating the 20th and 35th year of marriage.

Sapphire – September’s Birthstone

14 Kt White Gold 7.2 cts Blue Sapphire and Diamond Ring R61620In a set of poems released by Tiffany & Co. in 1870, each month is matched with a gemstone. The poem for September reads:
“A maiden born when September leaves
Are rustling in September’s breeze,
A sapphire on her brow should bind
`Twill cure diseases of the mind.”

Sapphire is also associated with the Zodiac sign of Taurus.

Sapphire is mostly known as a deep blue gemstone. Sapphire is a member of the corundum mineral family along with Ruby. Corundum forms in many different colors in nature. Corundum is made up of the elements Aluminum (Al) and Oxygen (O). Trace amounts of other elements such as Iron (Fe), Titanium (Ti), Chromium (Cr), Copper (Cu), or Magnesium (Mg) can give corundum blue, yellow, pink, purple, orange, or a greenish color. The pinkish red of Ruby comes from Chromium. Iron and Titanium are responsible for creating the brilliant blue Sapphire. Sapphire can also be found colorless.

Sapphire is extremely hard, next in hardness to diamond at 9 on the Mohs scale. Sapphire is extremely scratch and chemical resistant. It is also quite clear and can be used in lasers and for watch crystals, among other industrial purposes.

Madagascar is currently the leading gem quality Sapphire supplier in the world. Other major supplies come from Australia and Sri Lanka. In the USA, Sapphires can be found in certain areas of Montana.

The 423-carat (85 g) Logan sapphire in the National Museum of Natural History, in Washington, D.C., is one of the largest faceted gem-quality blue sapphires in existence.

In 1902 the French chemist Auguste Verneuil developed a process for producing synthetic sapphire crystals. A little over a decade later another process was developed which created better quality gemstones called the Czochralski process. Chemical dopants can be added to create artificial versions of the ruby, and all the other natural colors of sapphire, and in addition, other colors never seen in geological samples. Artificial sapphire material is identical to natural sapphire, except it can be made without the flaws that are found in natural stones. Most of the world’s synthetic sapphire is made in the United States and Russia.

Sapphire can also be enhanced by heat treating. The vast majority of natural sapphire on the market is heat treated to improve color and clarity.

A gift of a sapphire symbolizes a pledge of trust and loyalty. It is from this tradition that sapphire has long been a popular choice for engagement rings. Sapphire is known as a stone of wisdom, a royal stone of learning, mental acuity and psychic activation. As a talisman, Sapphire was thought to preserve chastity, discover fraud and treachery, protect its wearer from poison, plague, fever and skin diseases, and had great power in resisting black magic and ill-wishing. Buddhists believed it brought devotion and spiritual enlightenment, and the Hindus considered Sapphire as one of the “great gems” used in offerings in the temples for worship and to align astrological influences. In Christianity it was used in ecclesiastical rings, and was cherished by kings and nobility for its powers of protection and insight.

Peridot – August’s Birthstone

Peridot is a unique green colored gemstone from the Olivine mineral family. It can range from a quite yellow-green to olive green to brownish green. The rich slightly olive green is the most desired.R61918

Peridot is one of the few idiochromatic gemstones of the world, meaning that its color comes directly from its mineral chemical makeup and in turn it has only one color. Whereas many other gemstones’ colors come from the trace elements present along with the mineral composition and can be various colors depending on which trace elements are present. Peridot’s chemistry is made up of Silicon (Si) and Oxygen (O) along with Magnesium (Mg) and Iron (Fe). The richness of green depends on the amount of Iron content.

Peridot is fairly soft in gemstone terms, but harder than most metals. It is only 6.5-7 on mohs scale which puts it below most of the other common precious and semi-precious gemstones. It can scratch, crack or break if it is abused. Peridot is not resistant to acids like many other gemstones and will react unfavorably in a rhodium bath if not protected properly. Peridot is generally quite transparent but inclusions can create a soft or milky appearance.SB3660

The majority of the world’s Peridot gemstone supply comes from an Apache Native American reservation in Arizona, but it can be found on most of Earth’s continents in smaller quantities. Peridot is mostly found in smaller sizes, less than 5 carats, but any gem quality Peridot larger than 2 carats will exponentially increase in price the larger the size. The largest cut Peridot is in the Smithsonian in Washington, D.C. and weighs about 300 carats.

The only readily available Peridot simulants are colored Cubic Zirconia and colored glass or crystal, but occasionally corundum (Sapphire, Ruby) or Spinel are synthesized as Peridot simulants. Peridot itself is not generally synthesized as it is not expensive enough to be of much benefit. There are also no known treatments used for enhancing Peridot. Peridot is a special gemstone like Rubellite, where its color does not change hue dependent on the color temperature of the light source.

Peridot is commercially and traditionally known as the birthstone of August. Peridot is associated with love, truth, faithfulness and loyalty. It can also be associated by its green color with Mother Nature, life, growth and renewal.P8620

Peridot is mentioned in many ancient references as “chrysolite”. It is mentioned throughout the Bible, and early Christians considered it sacred. Today still, Catholic Bishops traditionally wear a ring of peridot and amethyst as a symbol of purity and morality.

Ruby – July’s Birthstone

SP10642Many cultures consider certain gemstones to signify a given birth month or sign. Each of these cultures specifies a slightly different set of birthstones. However, most include Ruby as July’s Birthstone.

In a set of poems released by Tiffany & Co. in 1870, each month is matched with a gemstone. The poem for July reads:
“The glowing ruby shall adorn,
Those who in July are born;
Then they’ll be exempt and free
From love’s doubts and anxiety.”

The Ruby is considered to be very powerful. Its deep red color is said to represent power, love and friendship. Spiritually many cultures feel it has the power to bring out passion, ward off danger, aid in blood circulation, detoxification and making wise decisions. In some cultures it also represents peace and contentment. Traditionally Ruby represents a 40th wedding anniversary.

Ruby is a close relative of Sapphire, in the mineral family of corundum, or aluminum oxide. The red color of Rubies mainly comes from the element chromium as part of the compound. In fact, if a Ruby is too light of pink in color saturation it is then referred to as a Pink Sapphire. In the corundum family, red is only Ruby and all other colors of corundum are Sapphires.

Ruby is one of the hardest naturally occurring minerals on the planet at 9.0 on Mohs scale of hardness, just below Diamond. In 1903 Auguste Verneuil created a process to make synthetic Rubies in his lab using a flame fusion method. Synthetic Rubies are used in some industrial lasers and mechanisms in heavy wear applications, and now that they are more commonly produced in gemstone quality they are used in jewelry.

High gemstone quality Rubies are extremely rare in nature which is one reason why they are one of the main four most sought precious gemstones along with Sapphire, Emerald and Diamond. For thousands of years and across many cultures Rubies have signified royalty or extreme wealth and importance. What better gem to represent this social significance, considering Ruby is a beautiful rich color, next in hardness to Diamond and very sparkly.

It is nearly impossible to find a natural Ruby that is free of imperfections. Many consider these imperfections to be part of the beauty and proof that the gem is natural or its “finger print.” Because of this, there are several Ruby look-a-likes that have been mistaken for Rubies for ages. Only recently (about 200 years ago) was the relation between Sapphire and Ruby known.  Many red Spinel and Garnet have been mistaken for Rubies and even many historic royal jewelry pieces actually contain these look-a-likes instead of the true corundum Rubies.

No other gemstone in history has been as symbolic as the Ruby, “king of gemstones.”
