This gorgeous and rare Antique Tiffany Set Diamond Ring dates to the 19th Century (1800's) Victorian Period. This ring holds a romantic antique euro cut diamond and is about 3.2mm in diameter. The stone is an original rare euro cut, with deep facets that catch the light unlike any modern day stone. These stones were faceted to catch candle light, thus having gorgeous romantic sparkle in the modern world. The diamond is Tiffany Set (not made by Tiffany and Co. of New York, nor is it implied in this listing) in an antique setting of 14K gold. Overall the ring measures about 1/4 inch long by about 11/16 inch wide and is in beautiful estate condition. Ring Size: about 5 (could be resized by your jeweler or ask me about using my experienced jeweler before shipping). This is truly a rare find and a beautiful fine antique.
