LEOPARD OPAL – A New Type of Mexican Opal
From the Ancient Mines of the Aztecs
Single Source Rare Variety of Opal
Leopard Opal is a variety of opalized vesicular basalt or Matrix Opal where the vesicles in the basalt have been filled with precious opal showing a strong colour pattern. Leopard Opal is a term that was coined during its reintroduced to the world gemstone markets at the Tucson Gem & Mineral Show in 1996 (Gems & Gemology, Gem News, Spring 1996, pp 54-55). Prior to 1996 Leopard Opal was known to only a select few individuals and has not been commercially available to the world markets. In the mid 1960s Leopard Opal was sold as Basalt Opal with modest acceptance by the North American gem and mineral community. In Mexico it is erroneously referred to as Opalo Negro or Black Opal but is not at all like Australian Black Opal.
There is anecdotal and physical evidence in the academic literature that these Leopard Opal deposits had been worked in the State of Hidalgo in pre-Columbian times - possibly by the Aztecs.
In 2006 a comprehensive scientific article on Leopard Opal was written by Coenraads & Zenil (Gems & Gemology, Winter 2006, Vol XLII, pp. 236-246) that discussed the geology and mode of formation of the opals on the original discovery deposit in the State of Hidalgo in Mexico. Subsequent to this discovery in 1965 other occurrences and potentially economic deposits of Leopard Opal have been discovered and are presently being exploited in the same vicinity.
In 2008 was the only known commercially producing Leopard Opal mine located in the State of Hidalgo in Mexico. This is a gemstone of significance because it occurs in substantial size blocks in volcanic rock making the Leopard Opal amenable to both polishing or faceting as well as suitable for gemstone carving and design work.
The Leopard Opal deposit is also associated with rarer quantities of high quality solid precious opal similar to the traditional Mexican and Australian opal.
