Pearl – June’s Birthstone

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.

What is a carat? Carat Weight and Millimeter Dimensions of a Gemstone Explained

We get quite a few inquiries from customers asking why the same millimeter size of gemstone has different carat weights from one gemstone to another. We also get customers saying he/she expected the gemstone to be larger/smaller because of the carat weight listed. We thought we should take a few minutes to explain why this is.

Aquamarine Gemstone Earrings - Peora JewelryCarat is a unit of measurement. It is used to measure mass or weight. You might think of diamonds when you hear the word “carat,” but it is actually used to measure all types of gemstones in jewelry.

A carat is exactly 200 milligrams or 0.2 grams. When referring to diamonds, most jewelers will use the term “point” or “pointer” to describe the size of a specimen. As you may have guessed, a “point” is 0.01 carat or 1/100th of a carat. So a ten “pointer” diamond would be 1/10th of a carat or 0.1 carat.

Now, when we try to equate carat weight to physical dimensions like millimeters, things get a bit tricky. Because diamonds and gemstones come in all sorts of shapes, each shape will convert differently between carats and millimeter size. With diamonds, it is generally accepted that a 1.00 carat round diamond will be 6.5 mm in diameter, but a 1.00 carat princess or square shape diamond will be 5.5 mm in diameter.

Emerald Gemstone Pendant Necklace - Peora JewelryDiamonds are more or less the standard comparison for carat weight and millimeter size. However, depending on the type of gemstone, the carats to millimeter difference can vary widely. Each gemstone or mineral type has a different density, which means it will convert from carats to millimeters differently.

Let’s take the diamond’s most commonly used inexpensive stand-in, Cubic Zirconia, as an example. The Cubic Zirconia is actually much denser than diamond, roughly 1.7 times as dense. So a 1.00 carat round CZ would actually be only a 5.3 mm diameter compared to the 6.5 mm of a diamond with the same carat weight. Some other gemstones that are more dense than diamonds include: sapphire, ruby, alexandrite and garnet.

Garnet Gemstone Ring - Peora JewelryConversely, let’s take Opal as another example. Opal is significantly less dense than diamond so it will be a much larger size stone with the same carat weight. A 1.00 carat round Opal will be almost 8 mm in diameter compared to the 6.5 mm 1.00 carat diamond. Other gemstones that are less dense than diamonds include: amethyst, tourmaline, aquamarine, emerald and quartz. Topaz and Peridot are fairly close in density to diamond.

So what do we take away from all of this? Basically, if you are searching online for a piece of gemstone jewelry that is not a diamond, you might as well disregard the carat weight altogether. Just look for the millimeter dimensions of the gem and pull out your trusty ruler.
