Beautiful vintage carved coral Buddha or female face head pendant / ring combination with diamonds, rubies, turquoise, in 18K yellow gold and in wonderful condition. This is an unusual piece, on the back there is a flat piece with a screw, you unscrew it and lift the bar to remove the ring to use this as a pendant. Never seen anything like this before. Ring is marked for 18K and we have had both ring and the gold enclosing the pendant tested, also all 18K gold. There are 5 diamonds on the crown, one lovely diamond in the third eye position, p brilliant marquise rubies, approximately 28 diamonds in rows surrounding the rubies, and 7 turquoise stones assumed to be Persian turquoise which would have been appropriate for the design and the time of this piece. The pendant measures 2 and 1/8" tall and 1" wide at widest point in the collar. The carved coral part is 1 and 1/4" long. The ring is a size 7 and of course being real gold it is easy to have this resized up or down. The pendant has a hanging loop at the top. We are dating this piece 1950's -1960's. In researching this design, we found only one, the shape of the pendant, with a lesser quality color head, lesser quality stones, and no apparatus on the back for a ring, also an estate piece. This would have been a very expensive piece even back when originally created. It is lovely worn as a ring, but magnificent as a pendant. I acquired this from a friend / dealer who specializes in only the finest and rarest pieces of estate jewelry, bought originally for myself. To me this is a museum quality piece. Maker unknown. Possibly Italian but that is only a guess, it may have originally been a design commissioned by a fine jewelry store with no two pieces identical, this piece very well may be a one of a kind. Our local jeweler tested the metal and also examined the stones for verification, his family fine jewelry shop has been in business for over 50 years and they had never seen anything like the design and ring option. This is a finely crafted piece, heavy for the size due to the components and also of a sturdy construction. Shipping seems high but it is due to insurance cost.
