Moissanite by Charles & Colvard 14K Gold GHI Round Cut Pendant w/ 18" Chain

Yellow Gold
By far the most common color of gold used in jewelry, yellow gold is gold in its natural shade. Yellow gold is usually alloyed with copper and silver to increase the strength of the metal. How yellow the metal is depends upon the content of gold. A 14-karat piece of jewelry will have a brighter yellow hue than a 10-karat piece. Likewise, an 18-karat piece of jewelry will have a deeper yellow than 14-karat gold, and so on.

White Gold
Although gold is most often thought of as having a soft, yellow glow, the metal is available in an entire spectrum of different hues. The different colors of gold depend upon with which metals the gold is alloyed, or mixed.

Increasing in popularity in recent years, white gold has become fashionable as the preferred cool and contemporary look. White gold boasts the same properties as classic yellow gold, but achieves its white color by mixing with different alloys. In general, white gold is created when a nickel or palladium alloy (zinc and copper) is used. White gold may also be plated with an even whiter metal, such as rhodium, to enhance its cool appearance. As well, a white gold setting can enhance the rapture of white diamonds.

Created Moissanite has very high dispersion and displays 2.4 times more fire than diamond (0.044). Its inherent high refractive index gives Moissanite a dazzling sparkle, while its precisely calibrated and carefully hand-cut facet patterns intensify fire and maximize brilliance.

Moissanite is extremely durable. It is harder (more resistant to scratching) than ruby or sapphire – second only to diamond – and it is resistant to breakage.

Larger sizes of near-colorless Moissanite (6.5mm or 1 carat and larger) might appear to have a slight color. A variety of factors, such as dispersion, tint and the type of jewelry setting, can create and affect this unique color appearance. Moissanite aficionados enjoy the slight hue that results in a very natural-looking gemstone, even though it's lab-created.

Natural mined diamonds are slightly heavier in weight than Moissanite stones because of Moissanite's chemical properties and structure. Essentially, Moissanite is less dense and therefore lighter than a diamond of the same size. For instance, an 8mm diamond with a 2.00 carat weight would compare to an 8mm Moissanite that has a carat weight of approximately 1.73. That said, the Moissanite would be classified as a 2.00 DEW (diamond equivalent weight) because of its size. This is a useful comparison tool when shopping for Moissanite as a diamond alternative.

Moissanite’s high dispersion produces flashes of rich rainbow (spectral) colors. The appearance and degree of these tints are less noticeable when Moissanite is set in jewelry. Jewelry set in gold (yellow, rose or white) and/or set in platinum will affect the face-up appearance of Moissanite.

Nobel Prize-winning chemist Dr. Henri Moissan discovered minute quantities of natural silicon carbide (later named Moissanite in his honor) while analyzing part of Arizona’s Diablo Canyon meteorite crater in 1893. Upon close inspection, he noticed the tiny crystals shimmered with brilliance and dispersion, although they were too limited in quantity and not large enough to use in jewelry.

Almost 100 years after Dr. Moissan's amazing discovery, a way to create Moissanite was developed. Appreciated for its overwhelming brilliance, Moissanite continues to take the jewelry world by storm.

Glossary

Brilliance: The white light leaving a jewel, traveling upward, which is visible to the eye. Brilliance is sometimes referred to as "sparkle."

Dispersion: Flashes of rainbow colors. Also called "fire."

Hardness: Resistance to scratching. The higher the number, the more resistant.

Luster: The shininess of a jewel.

Toughness: Resistance to breakage.
