This Aguascalientes fire agate gemstone measures 17.54 x 7.28 x 3.38 mm and weighs 3.75 carats. It features an unusual play of colors, a reddish orange crackle style fire on one end and an orange, green and dark purple bubble formation over the rest of the gem. The gem needs strong light to show the colors best. This polished flat bottomed stone is ready for final setting or display in a gemstone collection.

This fire agate gemstone comes from the Calvillo fire agate (Agata De Fuego) mines located in Aguascalientes, Mexico. Renowned for their high quality, these mines yield fire agates exhibiting a diverse range of rainbow colors, including reds, greens, purples, and blues.

The photographs shown highlight the stone’s color and formation under both artificial full spectrum indoor lighting and natural sunlight to best display its internal fire layers. The vibrant colors within fire agates arise from the Schiller effect, like what is seen in mother-of-pearl and opals. This phenomenon results from alternating layers of silica and iron oxide that diffract light, creating the interference patterns known as fire. Optimal lighting enhances this color play while in dimmer conditions the colors will be less vivid and the stone will appear darker with a brownish hue.

Aguascalientes Mexico Fire Agate Information

Aguascalientes Mexico is known for producing high quality fire agate gemstones, celebrated for their mesmerizing play of color and intricate internal banding. The fire agate rough from Aguascalientes is a treasure trove of fire agate beauty for collectors and carvers which prize this locality for its rough specimens.

Mexican fire agate rough often features these traits: Bright surface layers of multi-colored fire banding, creating dynamic flashes of red, orange, green, purple, and even electric blue. Some pieces from this area have a very dark colored chalcedony (the La Negrita mine in El Terrero de la Labor, Aguascalientes, Mexico) which provides a striking contrast from the colorful fire layers and can enhance the carving potential. These natural features make Aguascalientes fire agate rough ideal for lapidary artists, who seek material that allows for high contrast gemstones, which help reveal the stone’s full spectrum of fiery brilliance.
