Caring for Sterling Silver
Sterling silver becomes tarnished as the result of a natural chemical process that occurs when sterling silver is exposed to chemicals in the air, rubber, wool and latex. Humidity also plays a role in accelerating tarnishing. It's easy to keep your sterling silver sparkling, though, by taking a few steps to prevent tarnish and other wear and tear.

Pearl:
Often referred to as a gift from the sea, pearl's origin has been an object of folklore throughout history. Early Chinese myths told of pearls falling from the sky when dragons fought. Ancient Persian legend said that pearls were tears of the gods. In classical times, it was believed that pearls were formed when moonbeams lit upon shellfish, while Indian mythology suggested pearls were formed when dewdrops fell from the heavens into the sea.

In truth, pearls are lustrous gems with an organic origin. They are formed inside mollusks such as oysters, clams and mussels when an irritant such as a tiny stone, grain of sand or small parasite enters the mollusk's shell. To protect its soft inner body, the mollusk secretes a smooth, lustrous substance called nacre around the foreign object. Layer upon layer of nacre coats the irritant and hardens, ultimately forming a pearl.

This process of building a solid pearl can take up to seven or eight years. Generally, the thicker the nacre becomes, the richer the "glow" of the pearl and greater its value. While pearls that have formed on the inside of the shell (called blister pearls) are usually irregular in shape and have little commercial value, those that are formed within the tissue of the mollusk are either spherical or pear-shaped and are highly sought-after for jewelry. Most pearls on the market measure 7.0-7.5mm in diameter, but can be found as small as 1mm or as large as 20mm.

Although some pearls are found naturally in mollusks (considered the most valuable), the vast majority of pearls are grown, or cultured, on pearl farms. To instigate this culturing process, a small shell bead, or nucleus, is surgically inserted into the mantle of an oyster. Despite the fact that pearls are harvested in great quantities on pearl farms, producing a quality pearl is an extremely rare event. It is estimated that half of all nucleated oysters do not survive and, from those that do, only 20 percent create marketable pearls.

Since nacre is organic, pearls are quite "soft" and rank only a 2.5-4.5 on the Mohs Scale. The gems are very sensitive and special care should be taken when wearing and storing them.

The value of a pearl is judged by several factors and high-quality pearl strands should feature pearls well-matched in these factors: orient, the lustrous iridescence that's produced when light is reflected from the nacre, should glow with a soft brilliance; the nacre's texture should be clean and smooth, absent of spots, bumps or cracks; the shape of a pearl should be symmetrical and generally the rounder a pearl is, the higher its value; and although pearls come in many different colors (depending on the environment and species of mollusk), the most favored are those that have a rose-tinted hue.

Pearls are cultured in a variety of sizes, shapes and colors. Akoya pearls are the classic round pearls found in most pearl jewelry. They are mainly grown in the waters off Japan and are found in a range of hues, including white, cream, pink and peach. Mabe pearls are grown in Japan, Indonesia, French Polynesia and Australia. They are usually flat-backed and often called blister pearls because they form against the inside shells of oysters rather than within oysters' bodies. Tahitian pearls are grown in French Polynesia and come in a range of colors, including grey and black with green, purple or rose overtones. Because of their large size and unique dark colors, they command very high prices. Also prized for their large size, white South Sea pearls are grown in Australia, Indonesia, the Philippines and other areas of the South Pacific.

Freshwater pearls come in various colors and are grown in bays, lakes and rivers primarily in Japan, China, Europe and the United States (Mississippi River). They are often irregularly shaped and less lustrous than saltwater cultured pearls, making them substantially less expensive. Types of freshwater pearls include Biwa pearls from Lake Biwa in Japan, irregularly shaped baroque pearls and the exceptionally small seed pearls.

Pearls that develop within the soft tissue of mollusks encounter little resistance and therefore grow to be round or "regular" in shape. However, pearls that become lodged in the muscular tissue of shellfish experience resistance, so they free-form into irregular, unusual shapes. These "Baroque" pearls are asymmetrical and are world-renowned for their naturally unique beauty. Baroque pearls were especially prized by jewelers during the Renaissance.

In China, cultured pearls come mainly from freshwater rivers and ponds, whereas Japan is famous for culturing pearls along their saltwater coasts. Black pearls can be found in the Gulf of Mexico and in waters off some islands in the Pacific Ocean. In the warmer waters of the South Pacific, larger oysters produce South Sea cultured pearls and Tahitian black cultured pearls. Cultured pearl industries are also carried out in Australia and equatorial islands of the Pacific. For thousands of years, natural pearls have been harvested from the Persian Gulf, the Red Sea and the coasts of India and Sri Lanka. Natural saltwater pearls are also found in the waters off Indonesia, the Gulf of California and the Pacific coast of Mexico.

Pearls have been treasured throughout ancient folklore and history. Aphrodite, the Greek goddess of love, considered pearls to be sacred. The Greeks prized the gems for their beauty and believed wearing pearls would promote marital bliss and prevent newlywed women from crying. In ancient Rome, pearls were considered the ultimate symbol of wealth and status. The ancient Egyptians were buried with them and Cleopatra favored pearls immensely. It is said that while dining with Mark Anthony, she purposely dropped a pearl into her drink to demonstrate the wealth of her rule.

Today, the pearl is a universal symbol of innocence and purity. It is the birthstone for June and is considered the traditional gift for couples celebrating their 3rd and 30th wedding anniversaries. Many believe the gem gives wisdom through experience, quickens the laws of karma and cements engagements and love relationships. It is also considered to offer the powers of wealth, protection and luck.

The largest pearl in the world is approximately 3" x 2", weighing one-third of a pound. Called the Pearl of Asia, it was a gift from India's Shah Jahan to his favorite wife, for whom he also built the Taj Mahal. Another famous pearl is called "La Peregrina," or "The Wanderer," and is considered to be the most beautiful pearl in the world. Pear-shaped and 1-1/2" in length, it is said that 400 years ago the pearl was found by a slave in Panama, who gave it up in return for his freedom. The pearl turned up in 1969 at a New York auction house. It was purchased by actor Richard Burton for his wife, Elizabeth Taylor.

Zircon:
Zircon often suffers for its name’s similarity to “cubic zirconia,” the simulated diamond. The stone zircon, however, is actually a beautiful natural gemstone. It is named from the Persian word “zargun,” meaning “gold-colored.” This is despite the fact that it comes in a wide range of rainbow colors . The majority of zircons are brown or yellow-brown, while pure red and green are the most valuable colors. The yellow-red to reddish-brown variety is called “hyacinth.”

For many years, the most popular type of zircon was the colorless variety. More than any other natural stone, colorless zircons produce a brilliant sparkle similar to diamonds . The most popular color today tends to be the bright pastel blue variety. Sometimes called “starlite,” blue zircon has recently become considered an alternative birthstone for December.

Zircon is one of the heaviest gemstones, meaning that it will look smaller than other varieties of the same weight. It ranks a hardness between 6.5-7.5 on the Mohs Scale and is mined in Cambodia, Sri Lanka, Thailand, Myanmar and Australia.

Travelers during the 11th century wore zircon amulets for protection and to encourage welcome greetings on their journeys. In the Middle Ages, the stone was said to bring wisdom and prosperity to its owner. Hindu mythology even mentions the gem when referencing the Kalpa Tree, which was a glowing tree covered with gemstone fruit and leaves of zircon.

Turquoise:
One of the oldest known gems, turquoise has been prized for thousands of years. The Egyptians believed it had powerful mystical properties, and turquoise jewelry has been found interred with 7,500-year-old mummies. Ancient manuscripts from Persia, India, Afghanistan and Arabia say that the health of a person wearing turquoise could be assessed by variations in the color of the stone. Montezuma's treasure, now displayed in the British Museum, includes a carved serpent covered by a mosaic of turquoise.

Turquoise was especially revered by the Native American culture, an association that dates back to the Aztec empire more than 700 years ago. For the Aztecs, turquoise was reserved for the gods and mere mortals were forbidden to wear it. They believed it to be a gem of good fortune and a commodity more valuable than gold. Native Americans believed turquoise protected people from demons and they even placed turquoise in tombs to guard the dead. The stone's colors were thought to be symbolically blue for the heavens and green for the earth. Often warriors tied turquoise to their bows to ensure accurate shots.

Today, turquoise is still believed to provide protection and bring luck. It is said to also promote prosperity, love, healing, courage and friendship. The stone is thought to relax the mind and ease mental tension.

The gem's opaque turquoise color varies from shades of greenish blue to deep cobalt to sky blue. Some varieties display white or brown matrixes, which are streaks of the mother stone from which they came, while others have veins of black matrix running through them. Generally, the bluer the blue, the more highly valued the stone. A clear, even texture without mottling or veins is also preferred. The most rare and valuable color is an intense azure, but the most common is the mild to medium sky blue. Sometimes imitated by minerals such as chrysocolla, turquoise stones are often dyed or colored with coatings of various resins.

In the 13th century, turquoise was mistakenly believed to have come from the country of Turkey. Hence, its name came from the French word for Turkey, "Turquie". The stone was actually brought to Europe from Persia (now Iran), via Turkey. It is a mineral usually found in association with copper deposits and is sometimes mined as a by-product of copper mining.

Although turquoise is found in desert regions worldwide, especially in the southwestern United States, perhaps the finest and most valuable comes from the Sleeping Beauty mine in Globe, Arizona. It is named after the Sleeping Beauty Mountain which resembles a reclined woman in a slumbering state. Its turquoise is world renowned for its beauty that ranges from pure robin's egg blue to a darker royal blue.

While only ranking between 5.0 and 6.0 on the Mohs Scale of hardness, turquoise remains quite popular for jewelry. In Europe, turquoise rings are given as forget-me-not gifts, while in the United States, the stone is given as traditional 5th and 11th wedding anniversary gifts. It has even become a modern consideration for the December birthstone. When wearing turquoise over the years, the stone will absorb oil from a person's skin, causing a slight change to the color of turquoise.

Turquoise is commonly treated in various fashions to ensure its durability and visual appeal, especially when set in jewelry. If a stone has been treated, the type of process will be noted.

Turquoise is one of the oldest gemstones known in history going back 6,000 years BC and has been revered by almost every ancient culture. It is the alternate birthstone for December and has a Mohs rating of 5.0-6.0. Turquoise is a Hydrous Phosphate of Aluminum and Copper and may form as a chalky coating on rocks or finely disseminated crystals formed within small rock cavities. Rough such as this is not commercially viable, which has led to the development of reconstituted turquoise. Turquoise-bearing rock is pulverized and the turquoise is separated from the rock using a float process. The pulverized turquoise is then mixed with a colored resin, which is then injected into a mold to form a solid block. This is then cubed, preformed and fashioned into various shapes and sizes. It is an excellent method of using rough that would otherwise not be usable.

Earring Back Types

Butterfly Back: A double looped piece resembling a butterfly that fits over a post. Variations on this design are called push back clasps. The basic post and butterfly back are usually used for stud earrings and lighter weight drop earrings.

Hinged Snap Backs: This clasp features a hinged post that snaps into a groove on the back of the earring. It is commonly found on hoops. Sometimes the hinged post is curved to provide more room to fit around the ear, sometimes called a saddleback.

Hook Backs: This earring backing is simply a long, bent post that fits through the piercing. Hooks have several variations, most notably the shepherd's hook and the French hook. While thin wire hooks reduce the weight of long earrings, making them more comfortable, they aren't as secure as other clasp styles.

Lever Back: A hinged lever snaps shut against the curved post to form a closed loop around the ear lobe. This clasp is very secure and good for large or medium sized styles that drop just below the ear.

Omega: Also called French clips, this clasp has a straight post and a looped lever. The hinged lever closes around the post and is held against the ear with pressure. The omega clasp is the most secure clasp, especially for the larger, heavier earrings.

Screw back: This backing is a slight variation of the standard post and butterfly nut back. Instead of pushing on the back, the nut twists onto the threaded post. A screw back post design is often preferred for expensive diamond stud earrings that require increased security.

Fluorite
Fluorite earns the reputation as the most colorful mineral in the world. A rich purple color is its most famous and popular color, but its range of colors can be extremely variable with hues of blue, green, yellow, colorless, brown, red, pink, black and reddish orange. Intermediate pastels are also possible. Fluorite’s colorless variety is a rare find that makes it highly sought-after by collectors. Its brown variety features a distinctive iridescence and the more rare colors of rose and black are very attractive and in high demand. Most fluorites have a single color, but some have multiple colors that are arranged in bands or zones corresponding to the shapes of their crystals. A single crystal of fluorite could potentially have four or five different colors. Prized for its glassy luster, its crystals range from transparent to translucent.

Fluorite is strongly fluorescent with extremely variable colors. Typically it fluoresces blue or violet, but other fluorescent colors include yellow, green, red and white. It has a hardness of 4.0 on the Mohs Scale and has been known to fade in the sunlight. The mineral is found throughout the world, including Canada, Mexico, Brazil, Morocco, South Africa, Europe, Mongolia, China and Russia. In the United States, the states in the Mississippi Valley, especially Illinois, Kentucky and Ohio, have historically contained the largest deposits, but Colorado also has ample deposits of fluorite, as well.

The word fluorite comes from the Latin word meaning “to flow.” For centuries, the ancient Egyptians and Chinese used fluorite in carvings. Carved ornaments were even recovered from the ruins of Pompeii. Fluorite today is believed to be a spiritual stone that excels at calming the spirit and mind. Used as flux in the smelting of metallic ores , fluorite was originally referred to as “fluorspar” by miners and is still called that today.
