This 1940's Retro Style bracelet by Lustern is made of white gold-filled mesh links with a slider ornament of a flower spray set with sapphire blue crystals.
The ornament is 1 5/8" wide by 1 1/8" high by 3/8" deep. The mesh band is 5/8" wide.
There are both high-polish and satin-finish curls on the flower; the two blue crystals are prong-set. You can move the ornament away from the center if you wish but it was designed to sit atop the wrist with the clasp snugly closed in the back. The fold-over clasp has three slots so you can choose the slot for the most comfortable fit--in the last slot, the inner circumference will be about 6 1/4". (This is for a smaller wrist.)
"Lustern 1/20 12K G.F." is stamped on the clasp. Condition is very fine.
