4 pcs. glass bumpy enamel on copper red brown cabochons 15mm - f6683
15mm. Vintage glass bumpy enamel on copper red brown cabochons. These were handmade and not two are exactly alike. The backs have flaws where the counter enameling stuck to the screen during firing. Counter enameled pieces, such as these, are more durable and of higher quality. New old stock. Jewelry supplies.
