Tandem Ring, Leopard Opal

Leopard opal, tourmaline, 18k yellow gold. Size 9. [trigger heading="Why Is This Unique?" text=" Leopard opal is a very rare opal that comes from the lost mines of Zimapán in Mexico. The singular opal deposit is thought to have been worked in pre-Columbian times. While the Spanish Monarchy was more interested in gold, than opals, it is interesting to note that Zimapán is indicated as the source of many old opal specimens in museums around the world. One such example is a ring containing a “fire opal of Zimapán” worn by Antonio Eusebio de Cubero in a 17th century portrait by Diego Velázquez. "]
