This pretty bracelet has an abalone butterfly on its face with perfect coloration and pattern. The creator was obviously quite careful in his selection of the pieces. When I received the bracelet it was very dirty and it took some serious cleaning to get it to this point, though it could stand a bit more. There is a designers mark but it is too worn to read. I believe it is sterling silver but not marked. The bracelet is 6-inches long and is highly adjustable, and the butterfly is 1-5/8" long x 3/4" wide. A perfect gift for a butterfly lover!
