This is an unusually elaborate Carmen vintage expandable bracelet. The centerpiece is larger than most and is jeweled with vintage glass stones. Marked "Carmem, Made in the USA, The D.F.B. Co".
The center is 1 1/4" wide by 1 1/8" tall. The bracelet itself is 1/2" wide. It is adjustable and expands to go over the hand then hug the wrist.
It is made of warm and rich gold filled. The condition is very good keeping in mind that old glass stones don't sparkle like today's crystals. They have a softer sparkle.
