C. 1950 Vintage 3.00 ct. t.w. Diamond and .75 ct. t.w. Synthetic Sapphire Pin Pendant in Platinum. 17.75"

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.

CABLE: One of the most popular and classic of chain styles, created from interlocking oval links unvarying in size.

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.

REVOLVER: A safety that conceals the point of a pin and keeps it in place with a revolving lever mechanism.

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.

MARQUISE: An elliptical shape that comes to a point at the top and bottom. Sometimes referred to as a "navette."

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

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

Color Grade H-I: Near-colorless

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

SYNTHETIC SAPPHIRE: A gemstone that is created in a laboratory to mimic the actual properties of a natural sapphire. Commonly known as "created sapphire," it features the same deep color and transparent sparkle, but is significantly more affordable than a sapphire found in nature.
