Three tiny pendants with white topaz separate two prominent ones: one adorned with a green watermelon tourmaline that is set in solid 14K gold and the other one in sterling silver with 18K gold bimetal and silver dots. The sparkle in this necklace is hard to capture, but rest assured, it makes a big impression in person. A one-of-a-kind necklace, hangs 20.5 inches long. The bimetal is manufactured by rolling and bonding under heat and pressure a thin layer of 18K gold on a substrate of sterling silver. The beauty of gold at an affordable price.
