C. 1990 Vintage 1.90 Carat Pink Tourmaline Pendant Necklace with .95 ct. t.w. Diamonds in Platinum. 15.5"

PLATINUM: A rare precious metal cherished for its longevity and strength. Platinum is naturally white, durable, dense, and resilient to discoloration. Most platinum in jewelry is at least 95% pure since it does not require alloys or plating.

SPRINGRING CLASP: Invented in the early 1900s this diminutive device is highly effective. It's a hollow circular metal fastener with a spring opening. This keeps the clasp closed.

TOURMALINE: the "gemstone of the rainbow" comes in a dizzying array of colors and is usually created from more than a dozen elements, making it perfect for jewelry. The most popular tourmaline is deep pink, and a true favorite is watermelon... a gem of green and pink together.

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

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 I-J: Near-colorless

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