This borosilicate glass flower was handmade by me in the flame of my torch. I have bezel set it in fine silver on a copper base that measures 1 1/4 inches in diameter and has been textured and antiqued. I'm loving the mix of copper, silver and glass. The cab has a red purple and pink bloom inside. It measures 23mm in diameter (a little smaller than the diameter of a US quarter). It comes strung on an 18 inch gunmetal chain with a lobster clasp.
