These vintage German glass cabochons could have so many uses! If you are a metal artist, to set them in your work would be fun. If you are a miniaturist, they would make an amazing floor or tile bathroom. There are three colors available: a very typically Art Deco green, maroon, or a Peruvian opal like blue. The triangles are uniform and fit together beautifully. They are 18 mm at the base, 16 mm from the base to the tip and 4 mm high. The incising on the pattern is precise and sharp. I am an enthusiastic shopper and bought more than I can ever possibly use and I decided to stop hoarding and share. The price is for a bag of 10 pieces.
