Tiffany & Co Vintage 18KT Gold Ruby & Diamond Earrings

Tiffany & Co. vintage 18k gold diamond and ruby earrings. For pierced ears. Four round rubies and ten round diamonds in sets of two. Hallmarked Tiffany 18KP (Plum). They have some light surface scratches to the metal (not the stones) and one earring could use polishing in one area but they are in otherwise beautiful condition. They are over 30 years old. They will come with a newer Tiffany pouch and box that the consignor included. 18KP means the gold is guaranteed by the manufacturer to be not less than 18k. The karat mark followed by a P was introduced in the United States in 1978 and was used as a mark by Tiffany at that time.
