Gems en Vogue Paris 20" 4-5mm Freshwater Cultured Pearl & Multi Gemstone Drop Necklace

Barrel Clasp: Used on most rope chains to make the chain more secure. The barrel clasp looks like part of the chain and twists to get a pendant on and off.

Lobster Claw Clasp: As a traditional clasp style found in bracelets and necklaces, the lobster claw is generally reserved for heavier styles that may need added strength. The closure's shape is more oblong, similar to a teardrop shape, and is controlled by a tip that opens and closes the spring in the clasp.

Magnetic Clasp: A magnetic clasp relies on a strong internal magnet that works to pull both ends of the clasp together. In most cases, a magnetic clasp is used for light to medium weight jewelry pieces that do not put excessive stress on the magnet.

S-Clasp: An S-shaped piece of metal that connects a chain by hooking metal rings on each end of the S-shape.

Slide Insert Clasp: This type of clasp is exactly as it sounds. With a box-like shape that is hollow on the inside, the wearer will slide the nearly-flat tab into the box until it clicks, indicating a secure closure. On some jewelry, a slide insert clasp will be accompanied by a side safety catch, which adds strength and security to the clasp.

Spring Ring Clasp: One of the most common closure types, the spring ring clasp is typically used for light to medium weight bracelets or necklaces. It is round in its design and features a small tip which controls the opening and closing of the spring. The circle then closes around another smaller loop or link at the other end of the strand.

Toggle Clasp: A toggle clasp is a narrow piece of metal, usually designed in the shape of a bar, which is then pushed through a circular ring to act as a fastener. Unlike the lobster claw or spring ring clasps, a toggle clasp is not controlled by a spring. The pretty design is less secure than other closure types, but is usually meant to be a big part of the design and is meant to "show". The clasp is an attractive way to secure a chunkier link bracelet or necklace.

Necklace Sizing
The length of a necklace or chain you buy depends upon a number of factors, including what you will be wearing with it and your neck size.

To measure your neck, wrap a soft, flexible tape measure around the base of your neck. This is the same measurement used for collar sizes in men's shirts. A good rule of thumb is to buy a necklace or chain a minimum of two sizes up from your neck measurement.

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.

Sapphire:
An ancient Persian legend states the Earth rests on a gigantic sapphire that gives its blue reflection to the sky. The most popular colors for sapphires range from light blue to a blue that appears black. Hence, the name was derived from the Latin form of the Greek word for blue, "sapphirus." These blue colors are caused by iron and titanium in the stone. Bright daylight makes most sapphires shine more vividly than the somewhat muted artificial light. So the most highly cherished color for blue sapphires is not the darkest blue, but a deep and satiated blue, which even in dim, artificial light remains to appear blue.

While sapphires are best known for being velvety blue, it was decided long ago to consider all gemstones of the mineral family corundum to be sapphires. Non-blue sapphires are termed "fancy" and can be nearly any color, including yellow, green, white, pink, orange, brown, purple and even black. Red corundum is the exception, however, and was given the special name of "ruby."

In lighter-colored sapphires, the shade of color is determined by how the stone is cut. A cutter must take special care with sapphires. Not only do they rank a 9.0 on the Mohs Scale, second only to diamonds in hardness, but they display a different coloring and satiation depending on the perspective. The cutter must align the orientation of the stone in such a way as to bring about the best possible display of color.

There are a great number of varieties of sapphire, many of which are quite rare and highly sought-after in the gemstone market. A rare orange-pink variety, known as padparadscha, can be even more valuable than blue sapphire. Given the poetic name meaning "lotus blossom," it features a delicate orange color with pink undertones

Another rare variety of sapphire is known as the color-changing sapphire. This stone exhibits different colors in different light. In natural light, color-changing sapphire is blue, but in artificial light, it is violet. This effect is the same phenomenon seen in alexandrite.

For experts and connoisseurs, the Kashmir-color is considered the most beautiful and valuable shade. It features a pure and intensive blue, which is enhanced by a fine, silky gloss. Its color does not change in artificial light, but remains intense with a deep, velvety sheen. Setting the standard for the color of top-quality sapphires, Kashmir sapphires were found in 1880 after an avalanche. They were intensely mined for only eight years until the source was depleted. The Burma-color is also considered especially valuable, ranging from rich royal blue to deep cornflower blue. Ceylon sapphires are prized as well for the luminosity and brilliance of their light to medium blue color.

There is a translucent variety of sapphire, called star sapphire, which displays a six-point star when cut into a smooth domed cabochon. The mineral rutile is embedded in an asterisk-shape within the stone, causing light to reflect in a phenomenon called "asterism." Six- or twelve-ray stars appear to magically glide across the surface of the stones as they are moved. Star sapphires and rubies are expensive rarities and should always display the stars exactly in the center of the gem. The star stone is said to be the home of each person's angel, who lives there in contentment with the sapphire's spirit.

White sapphires have become a very suitable diamond substitute. With their high light refraction and level of hardness, they provide a less expensive alternative that is still very capable of turning heads with a very convincing sparkle.

The oldest sapphire mines are situated in Ceylon, where gemstones were mined in ancient times. Most blue sapphires today come from Thailand or Australia, but sapphires from Kashmir and Myanmar are highly prized. A large sapphire occurrence stretches across several miles in Madagascar. There are also two large occurrences in Tanzania, where smaller, yet high-quality sapphires are found. The stone is also mined in many other parts of the world.

Sapphires are readily available in sizes of up to 2.00ct, but gems weighing 5.00-10.00ct are not unusual. The cushion-cut Logan Sapphire from Sri Lanka weighs an astounding 423.00ct and can be seen at the Smithsonian Institution in Washington, D.C. There is also a 258.00ct stone set in the Russian crown, which is kept in the Diamond Fund in Moscow.

Because the gem has long symbolized sincere love and enduring faithfulness, blue sapphires are often given in engagement rings to express commitment and loyalty. Many women throughout the world decide on the blue stone for their engagement rings, as the gem also represents truth, friendship, harmony and consistency. Sapphire blue has become a color related to anything permanent and reliable, making it an ideal stone to symbolize the promise of marriage.

Often referred to as "Gem of the Heavens," sapphire also symbolizes a noble soul. It is September's birthstone and is traditionally given as 5th and 45th wedding anniversary gifts. Star sapphires are given for the 65th anniversary. The color sapphire-blue is known for representing clarity and competence. In fact, the first computer to ever declare victory over a chess grandmaster and world champion was named "Deep Blue."

Sapphires have been associated with magical powers throughout the ages. The Greeks identified white sapphires with Apollo and the oracles at Delphi used them to tap into the subconscious and super conscious. In the 13th century, it was said that when worn, sapphires cooled the inner heat of anger. Soldiers wore them to prevent capture by enemies and kings wore the gemstone to defend against harm and put themselves in divine favor. This supposed "divine favor" is why sapphires were often the gemstone of choice for high priests and royalty throughout history. In fact, the British Crown Jewels contain a number of notable sapphires.

During the Middle Ages, sapphires symbolized the tranquility of the heavens and wearing them was thought to bring peace, happiness and purity of the soul. Medieval priests and monks would wear sapphire jewelry believing it had the ability to quell wicked impulses and impure thoughts. The color blue became the symbol of the union between a priest and the heavens, so sapphires came to be adorned on the rings of bishops.

Today, sapphires are still believed to hold special powers. It can be considered an aid to psycho kinesis, telepathy and clairvoyance, while providing spiritual enlightenment and inner peace. White sapphires, like diamonds, are considered the guardians of love, enhancing it and ensuring fidelity in marriage. The most powerful type of the gem is said to be the star sapphire. They are believed to protect against negative energy and have a calming effect that allows the mind to experience tranquility, joy and clear thinking.

Apatite
The name apatite comes from a Greek word "apatos," meaning deception, which alludes to the mineral's similarity with other more valuable minerals such as olivine, peridot and beryl. It can be transparent to opaque, with color that is typically green but can also be yellow, blue, reddish brown, violet and colorless. This gem exhibits an unusual "partially dissolved" look similar to the look of previously sucked-on hard candy.

Apatite is widely distributed in all rock types, but is usually just found as small grains or fragments. Large and well-formed crystals, though, can be found in certain contact metamorphic rocks; but with a hardness of 5.0 on the Mohs Scale, the softness of apatite prevents wide distribution in the jewelry market. Apatite occurs generally in rather rough prismatic crystals, the largest being 4 inches long and 1 inch in diameter.

In most limestone quarries, careful search shows the presence of small prisms of bright green apatite in the limestone. Notable occurrences include Germany, Brazil, Russia, Myanmar (Burma), Sri Lanka (Ceylon), Canada, East Africa, Sweden, Spain and Mexico.

Palladium:
A selection of our jewelry is made of sterling palladium alloy. Palladium is a member of the platinum group of precious metals. By replacing a portion of the copper content used in standard sterling silver with palladium, this proprietary formula renders a precious metal with superior performance attributes. Sterling palladium is five times more tarnish-resistant than standard sterling silver and has strength similar to that of 14K gold.

Palladium has been used as a precious metal in jewelry since 1939, originally as an alternative to platinum for making white gold. Its naturally white color requires no rhodium plating. Additionally, palladium is proportionally much lighter than platinum and is ideal for use in heavier gemstone jewelry. It is a more expensive alloy than nickel, but it seldom causes the allergic reactions that nickel alloy can.
