This calligraphy stone pendant is handcrafted from 14K/20 gold filled wire and a calligraphy stone cabochon (cab) from India. This cabochon is not highly polished. It has more of a matte finish. It is is finished off with one of my frothy hearts, accented with 2 fire-polished, czech glass beads. 14K/20 gold filled wire is basically a tube of 14K gold with a jeweler’s wire down the center for flexibility. It wears well, does not tarnish, and has the same allergy reactions (or non-reactions) as 14K gold. Each of my cabochon pendants are "one-of-a-kind" and you are selecting the actual one you will be receiving. The chain is not included, but I do have a selection of chains if you need one. approximately 7/8" x 3 1/8 " 22mm x 80mm 6mm bail
