Opal ("Fever Opal")We picked up this stone from a friend who calls it "Fever Opal" as he said it wasn't "Fire Opal", per se, due to the mix of colors. The stone is about 50% colorless, but the other half shows a brilliant reddish orange hue creating a rarely seen two tone effect. Typically, the Fire Jelly Opals from Queretaro are a sold hue (yellow, orange or red), and a mixing of colors is rarely seen, especially in faceted material. This attractive "Emerald" cut gem

These "Copper Rose" specimens are classics from the mine that bears the same name

simply because most gem dealers don't carry them
