These stones measure 8 x 10mm. They are made in West Germany. These are vintage Topaz glass stone cabochons with a Aurora finish. The backside has a foil back for reflection. The AB finish also gives them some reflective quality. They are not flat on the back like cabochons, so you will need to set them into your design. Their height is 4.5mm with the pointed backing. Really pretty and unusual to see this sort of stone. You will receive 4 stones per lot.
