Gems en Vogue 18K Gold Plated Choice of Tumbled Bead Gem 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.

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.

Tanzanite
No other gemstone discovery has made a bigger impact on the jewelry market than the recent newcomer, tanzanite. Its luscious color, and the fact that the stone is found in only one location throughout the world, makes tanzanite an exceptionally rare, valuable and highly sought-after gem.

Tanzanite’s mesmerizing saturation of color is what has made the stone so popular. It is the blue variety of the mineral zoisite and occurs in a beautiful range of colors. Rarely pure blue, the gem almost always displays signature overtones of purple. In smaller sizes, it tends toward light tones such as lavender, while in larger sizes, the gem typically displays deeper, richer blues and purples. The finest quality tanzanite is usually deep blue or violet, which is extremely spectacular in sizes above ten carats.

Tanzanite is pleochroic, meaning it shows the appearance of several colors in the same stone, depending on perspective. From different angles, the gem can appear blue, purple, yellow, grey or brown. Most rough crystals show a large proportion of brown shades, since tanzanite in its natural form is typically brown with red, orange, yellow or bronze hues.

Gem cutters may change this coloring by heating the stone to 500°C. This heat treatment releases the intense violet-blue colors for which the stone is famous. According to legend, the effect of heat on tanzanite was first discovered when brown zoisite crystals were caught on fire by a lightning strike. Local cattle herders noticed the beautiful blue crystals sparkling in the sun and picked them up, becoming the first tanzanite collectors.

The gem was first discovered near the base of Mount Kilimanjaro in the Merelani Hills of east-African Tanzania in 1967. This breathtaking location is the only known mining site on Earth for tanzanite. Right after its discovery, New York jeweler Louis Comfort Tiffany was presented with the first stones. Knowing it was going to be a sensation, he recommended finding a new name for the gem, since the gemological denomination “blue zoisite” reminded him of the word “suicide.” Tiffany suggested the name tanzanite, derived from its place of occurrence, and the new name quickly became established on the market. Tiffany & Co introduced the stone to the public in a spectacular promotional campaign two years after it had been discovered. It was enthusiastically celebrated as the “Gemstone of the 20th Century.”

A noted 122.70ct faceted tanzanite dubbed the “Midnight Blue” is on display at the Smithsonian Institution in Washington, D.C. In 1996, a 255.00ct tanzanite crystal was discovered near Arusha, but because of its many inclusions, it proved to be of little market value. Tanzanite ranks a hardness of 6.5-7.0 on the Mohs Scale and has become the traditional gift for couples celebrating their 24th anniversaries.

High-quality and larger-size tanzanites can be sold at extremely premium prices. Although demand for this beautiful gem continues to grow, supply shortages in recent years have hampered production and caused price fluctuations. In 1998, the weather phenomenon known as “El Nino” soaked Tanzania with heavy rains during what should have been the drought period. When the monsoons hit, the groundwater swells were high and caused devastating floods. Mines caved in and all hopes of finding additional tanzanite rough were swept away.

Because it is such a new gemstone, there is little folklore, superstitions or healing properties surrounding tanzanite. Some believe the stone helps people to be more practical, realistic and honest. It is thought to uplift and open the heart while helping one cope with change.

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.
