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.

BALL: A round, bead-like clasp. Sometimes adorned with gemstones or texturing, ball clasps provide a decorative closure that does not take away from the design of a necklace or bracelet.

SOUTH SEA PEARLS: With a dramatic 9mm-20mm size and glowing satiny luster, South Sea pearls are among the rarest and most coveted of cultured pearls. Found in shades of white, silver and gold, South Sea pearls are an exquisite sight in jewelry designs.

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 G-H: Near-colorless
