A delicate-sized hoop, with dangling crystal of Aquamarine or Tourmaline. Inspired by ancient jewelry from India. Made in Sterling Silver, 24-karat Gold Plated. Hoop Diameter: 2.2 cm or 7/8 inch Aquamarine and Tourmaline stones were not polished or cut, they are the crystal of the mineral as it was found on earth. Nowadays it is very rare to find stones in their natural crystal cut because mining currently involves drilling, blasting and hauling, which destroys or damages almost all crystal pockets.
