These vintage West German glass intaglio cabochons were manufactured in the 1960’s. They are heart shaped, with a reverse painted cross. The background color is vitrail, which is a vibrant mix of fuschia, gold, green and blue depending on the lighting. I tried to get several shots under different lighting conditions and angles to give a sense of how varied and flashy this effect really is.
The stones measure about 18mm high by 16mm wide at the highest and widest points. They have flat, silver foiled backs. Some of the stones have minor nicks and foil flaking, due to age.
