Antique Czech 27x19mm sapphire blue hand octagon faceted glass rhinestone

Antique Czech 27x19mm sapphire blue hand octagon faceted glass rhinestone. A beautiful rare glass rhinestone, made in the 1920's with a hand faceted finish. This has incredible faceting and is gem like which is not reflected in the photography. Sewn onto an original sales sample card, part of a set which would have been used to demonstrate the colors, shapes and sizes of rhinestones available. The colors on these antique stones are rarely reproduced. In original untouched condition with a small corner nick from the hand faceting. Please note antique rhinestones rarely conform to modern sizes and sometimes may not be perfectly symmetrical. 
For making jewelry, fashion design, sewing, art and crafting. 

Origin: Northern Bohemia circa 1920's
Size: 27 x 19mm; 1.05" x 12/16". 9mm thick

Please note the color is slightly darker than the photos suggest
