Honduran Opal was formed during volcanic eruptions in the country of Honduras in Central America, between Nicaragua and Guatemala. They are the oldest opal mines in the world, and a lot of Honduran farmers actually subsidise their income by mining opal. Honduran Opal is similar to the Andamooka Opal in its appearance and composition in that it is opal within a matrix, in this case volcanic black basalt. These opals are often coated in resin or similar to seal the stone and stop it absorbing anything else, and to show off the colour.
