Fire opal has been found in Ethiopia for many years, however this new deposit also known as 'desert opal,' typically has a white silica base, compared to the previous finds that were brown or occasionally black. Desert opal can be brilliant and colorful. It is a new deposit, and as such untested for very long time horizons (like Australian). This is a brilliant "nugget," of fire opal. The color play is red, green, yellow and blue. The fire is way better in person. This is a high grade piece that is getting hard to get now. It weighs 31 carats.
