Opal and .70 ct. t.w. Ruby Pendant with .33 ct. t.w. Diamonds in 18kt White Gold

18KT: Karat (abbreviated kt or K) is a unit that indicates the purity of gold in the metal. 18kt is 75% gold. In Europe, 18K yellow gold is most favored and used in jewelry.

WHITE GOLD: Gold is a precious metal which is naturally quite soft. To give it a white color and increase its strength, gold is alloyed with white metals, such as silver and/or palladium, and often plated with rhodium. The purity of the metal is indicated by a unit called a "karat," with 24kt having the highest percentage of natural gold.

HINGED: A bale with a hinge. The hinge allows the pendant to be placed on and taken off a chain easily and without sliding. Ideal for putting pendants on chains that have large clasps.

RUBY: A bold fiery stone, the ruby is a symbol of wealth, vitality and love. When cut and polished, the ruby's high luster is as dazzling as a diamond's. Ruby jewelry makes the perfect gift for loved ones and is the birthstone for July.

Diamond: The hardest and most brilliant of all gemstones, a diamond can make the heart race with its pure and fiery spark. An ancient symbol of love, a diamond is the preferred gemstone for tokens of affection, such as rings, earrings, necklaces and bracelets. Diamond is the birthstone for April.

BRILLIANT: A gemstone cut to enhance brilliance without sacrificing much carat weight. Typically has 58 facets.

Color Grade H-I: Near-colorless

CLARITY SI1-SI2: Slightly Included. Inclusions are noticeable under 10x magnification.

OPAL: With an iridescent luster that can reveal a beautiful kaleidoscope of color, the opal has inspired many myths and legends. A white opal with swirls of soft pastel shades is popular for jewelry, but opals also come in black and blue. Opal is the gemstone for October birthdays.

PEAR: Similar to the outline of a pear fruit, this is a round shape that comes to a point on one side.

CABOCHON: A style of cutting gemstones to achieve a smooth, domed surface with an absence of facets.
