This listing is for a handmade gold filled or sterling silver ring with a 5-8mm bicolor or tricolor pink, green and gold natural tourmaline gemstone. Please see other listings for other colors. Each faceted stone is unique and is a slightly irregular oval/round shape. Please message me if you have specific requests regarding the color or size of the stone and I will do my best to accommodate. These rings are made with high quality 12-14k gold fill with a jeweler’s brass core or sterling silver.
