This is a vintage handmade green copper turquoise pendant. The pendant features a large, oval-shaped gemstone with a vibrant green color and copper matrix set in a sterling silver, scalloped bezel I'm not an expert in turquoise I went by pics - it is a real stone no doubt very cold to touch So pretty It appears to have been plated in either gold or rose gold or even copper and is wearing off but the silver shines thru. Stamped at bale & tested at back for silver. I think it makes it even more unique ---fyi •vintage & costume pieces can show wear. •May require cleaning I leave as found •pet friendly; non smokers •ship M-F only
