I have paired a vintage Mexico sterling silver 3-section abalone pendant with a sterling silver tube & ring chain with artisan made hook closure. The abalone is really unusual & this is one of a kind necklace. Just a gorgeous necklace. Mark on pendant is Mexico Sterling Silver Artisan Chain is 18 inches. Pendant height is 2 3/8 inches. Pendant width is 1 1/8 inches. Total weight is 8 grams. Abalone is a stunning shell that is known for its iridescence & unique, vivid color palette. The gemstone has been used in jewelry for thousands of years & continues to be popular in modern designs. Affordable, stylish & distinctive, it’s the ideal choice to shake up your wardrobe & add a burst of color to your look. Also known as abalone shell & oyster shell, the abalone is where Mother of Pearl is found. They reside in South Africa, where they’re considered very valuable. They can also be found in Japan, Australia, New Zealand, & on the west coast of North America. The abalone is the exoskeleton of a sea creature.
