Simbircite, a rare stone that has taken over 80 million years to form! The pendant is a Simbercite stone hand wrapped in leather.( 2 inches x 1 1/2 inches) The great thing about this mounting, is that it is unbelievably light. You get a bold statment with out any weight. The necklace is 18 inches long and is made of 3 different cuts of tigers eye, genuine pearls, onyx and 14k gold filled accent beads. The closure is a toggle clasp. It is an amazing piece!
