This platinum and diamond engagement ring is circa early 1900's. It's a beautiful engraved mounting with a squared off center box in which is set a quality European cut diamond weighing 1.00 carats. The stone has been graded an approximate I color with a VS clarity. This one of a kind mounting is platinum and the handmade detail is wonderful. An additional twelve (12) smaller diamonds are set in the mounting's swirl and loop design and the sides of the ring have been engraved.
