TJC gold plated (white) 925 onyx and peridot pendant no chain

signed pendant with onyx and I believe it's peridot by the color close up but could be quartz or topaz or let's just say I dont know lol. gorgeous pendant with silverwork to look like diamonds. white gold plated sterling signed tjc. I do have sterling chains available for an additional $15 not junk either. but that's the combined price as I have to buy them retail currently. 5+ grams weight the pendant is slightly over an inch length and slightly less then a half inch wide. New without tags
