This is a wonderful, huge natural fire opal. This stone was mined in Ethiopia in a location close to Welo. The color is a vivid, fiery orange. This is from 20 year old rough that was mined before the main Welo opal deposit was discovered. The opal from this source is completely stable. The clarity is eye clean with high transparency. The stone comes with a certification from an independent gem laboratory. This stone will make an absolutely superb large pendant.
