Circa 1955, designed as a frosted and carved rock crystal calla lily studded with one small round full cut diamond, completed by a gold stem and center, mounted in 18KT yellow gold, signed "Schlumberger and Tiffany & Co." and stamped 18KT on the pin closure.

2.75 x 1.25 in.

Approximately 10.9 dwt.

The brooch is in fair condition overall with two breaks to the rock crystal, one of which is to the reverse and not noticeable when worn, the second piece is broken out near the center of the flower. Overall it is a fairly clean break and not readily noticeable when worn. It may be possible although it is not guaranteed that the rock crystal could be smoothed out where both breaks have occurred for an even better appearance by an extremely skilled jeweler or by Tiffany & Co. The rock crystal is secured by screws and is somewhat loose but should be able to be tightened by a jeweler. The Schlumberger signature is partially obscured due to strike and as made, but is still very much legible.

$400 - 600
