C. 1990 Vintage 4.66 Carat Ceylon Sapphire and 2.20 ct. t.w. Diamond Ring in Platinum and 18kt Yellow Gold. Size 7

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.

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.

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.

TAPERED BAGUETTE: A modification to the baguette shape, where an elongated rectangle gemstone narrows on one side.

Color Grade H-I: Near-colorless

Clarity VS1-VS2: Very slightly included. Inclusions are observed with effort under 10x magnification, but can be characterized as minor.

SAPPHIRE: A favorite gemstone of ancient priests and royalty, the sapphire radiates sophistication and grace. This prized gem comes in every hue of blue, plus the more unexpected shades of pink, yellow, green and orange, and is September's birthstone.

OVAL: An elliptical shape that resembles an egg.
