This is the Celebrity bracelet from Sarah Coventry and is from 1964 or earlier.
It was never sold but given as a hostess gift as a reward for high sales at a party.
Large, rectangular, smoky gray/black stones (with a hint of green and even a little purple in the right light) are prong set in a lacy, openwork silvertone frame with gray "black diamond" Austrian crystal rhinestones adding to the sparkle.
Width: about 1 3/8 inches
Length: about 7 3/8 inches when clasped, so it would fit a wrist up to that size, but would be more comfortable on a slightly smaller wrist.
In the photo with 2 bracelets, this one is the top one.
I see a small amount of normal wear and minor scratches from use as is expected of vintage jewelry.
This is reflected in the price.
Signed "(c)Sarah Cov"
*Please check to make sure the stones, rhinestones, safety chain and clasp... are very secure and then have the pieces of vintage jewelry gently cleaned by a jeweler or collector who understands vintage jewelry.
The old glue sometimes gives out so check the rhinestones while holding the bracelet over a tray (to catch any that come loose so that you do not lose them) before each use or cleaning.
*All items are "as is" and there are no returns so please read the descriptions and see the photos before you buy.
