C. 1930 Vintage Hand-Engraved Diamond Pin in Platinum and 10kt Rose Gold

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.

10KT: Karat (abbreviated kt or K) is a unit that indicates the purity of gold in the metal. 10kt is 41.67% gold.

TEXTURED: A unique and varying finish with a tactile surface applied through various techniques, both by hand and with machinery.

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

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.

OLD MINE CUT: An antique gemstone cut dating back to the 1700s. Features a rounded square silhouette similar to the modern cushion-cut, but conforms to the shape of the rough gemstone in order to preserve the weight. The culet is usually large enough to be easily seen through the table of the diamond.
