This Sapphire glass diamond shaped pin is a very old design that was made in West Germany in the 1940-1950 era. Even though the pin was made in the Mid-Century Modern period, it is an Art Deco style.
The deep sapphire glass diamond has a flat tabletop with unique pentagonal and triangular facets around the perimeter. The back of the crystal is faceted as well and the crystal is open backed, allowing light to pass through creating radiant brillance. The glass cab is prong set in a gold metal twisted rope frame, which is set towards the back, showing off the prominent depth of the diamond cut glass cab.
What is very admirable about this pin is the deep cobalt blue color of the glass. It is not seen in jewelry often. Only very old pieces that had high concentrations of cobalt. This comparison is also true for very old and not so old cobalt glass Apothecary jars.
Signed West Germany, the pin is petite in size at 1 1/4" long x 3/4" tall, or 32 mm x 18 mm. The top and sides are perfect with no scratches, scuffs, or facet wear. There are a few very microscopic flea bites where the glass cab meets the frame, near the prongs, hardly worth noting. There is no gold metal wear or loss of gold and the entire pin is microscopically clean and bright.
Comes gift wrapped and shipped in a new presentation jewelry box.
