Overall dimensions: approx 2" x 5/8" x 1/3"

One Tiffany&Co. platinum brooch set with a 1.4ct natural emerald and approximately 5cts of natural diamonds. This vintage brooch is a hand-assembled art-deco design, constructed of platinum, with a large central rectangular step cut emerald surrounded by six different cuts of diamonds, totaling 80 separate diamonds. I believe it is from the 1920s-1930s. It is stamped with "TIFFANY&CO." and "IRID.PLAT" (indicating the iridium-platinum alloy commonly used in jewelry to increase strength and hardness) on the rear platinum edges, as you can see in the pictures. I received the brooch from my grandmother, who had inherited it from her mother when she passed away in 1986. I have a couple of documents from my grandmother indicating family ownership/transfer, originals of which you will receive upon purchase of the item.

As you can see in the front side photos, the emerald has a chip in its top right corner, which is approximately 1.5mm x 1.5mm in size. The emerald itself is 9mm x 6mm x 3mm. Other than this chip, the brooch is in very good condition overall, with the diamond surfaces and polish being superb. The other marks that you see in the emerald are actually inclusions inside the stone, which is typical of natural emeralds used in vintage jewelry from this era.

The brooch recently had some minor cosmetic service done on it at Tiffany in NYC. The Tiffany service order and receipt are in the attached pictures. Also pictured is the appraisal that I had done on the brooch at American Institute of Gemological Research in Denver, CO. Warren Pressler of AIGR confirmed to me the Tiffany origin/make, based on his evaluation of the design, workmanship, insignia, and gemstone quality. It is of the very highest caliber craftsmanship and execution, and is truly a uniquely beautiful piece and a rare find.

See specs about the brooch below, as well as in the AIGR appraisal shown in the pictures.
