This borosilicate glass flower was handmade by me in the flame of my torch. I have bezel set it in fine silver on a brass flower shaped base that measures 1 1/2 inches in diameter and has been textured and antiqued. I'm loving the mix of metals and glass. The cab has a bloom of pink and purple inside. It measures 21mm in diameter (about the diameter of a US nickel). It comes strung on a 18 inch gunmetal chain with a lobster clasp.
