Lot Details
Property of a Mid-West Opal Collector
Fine Orange Jelly Opal
Magdelena, Jalisco, Mexico
One of the two largest sites for mining the Mexican fire opal, is located near Magdalena, Jalisco, a small city located approximately 100 miles east of Vallarta. Magdalena is in a region laden with igneous rocks, obsidian, volcanic lava, and more than 300 opal mines.

Mexican fire opals consist of silicon dioxide or silica spheres arranged in an orderly pattern with iron oxide dispersed throughout giving the fire opal its distinctive brilliant flame-like colors of yellow, orange, and red. The three most important attributes of the fire opal are body colors, transparency, and play-of-color (differing colors when viewed from various angles). Simply put, the greater the play-of-color, the more precious the gemstone.

Mexican fire opal was known by the Aztecs and was used by Mayans as well for ritualistic purposes and in various mosaics. Even today many connoisseurs believe that fire opals bestow courage, stamina, and energy to the wearer due to its warm, fiery orange-red colors. This is an exceptional oval cabochon with broad flashes of brilliant blood-red and green; it has excellent proportions for mounting as a ring. The even orange body color displaying a fantastic array of spectral colors which hover within. This is a true gem for the collector of precious fire opals.
Weighing approximately 9.68 carats and measuring 16.0 x 11.5 x 9.5mm
