C. 1925 Vintage 1.55 ct. t.w. Diamond Triangle Pendant Necklace in Platinum and 14kt Yellow Gold. 16"

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.

14KT: Karat (abbreviated kt or K) is a unit that indicates the purity of gold in the metal. 14kt is 58.33% gold. In the United States, 14K yellow gold is most favored and used in jewelry.

SINGAPORE: A twisted chain linking pattern that blends the look of a curb chain with that of a rope chain. The flat and curvaceous links of a Singapore are often described as having the look and feel of liquid, even when unraveled.

LOBSTER CLASP: named after the pinching style of the hook, this clasp is often shaped like a lobster's claw. Use your finger to work the lever to open the clasp.

FIXED: A bale that is worked into the actual design of a pendant. Typically seen in slide pendants.

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.
