The colors rate 5 on the scale of 5 for brightness and include green, violet and turquoise. The colors flash and streak brilliantly across the face with rotation of the opal and there is good play of color. There is a small natural depression to the rear edge of the opal. This solid black matrix boulder opal has been mined from the Queensland boulder opal fields.The ironstone of the opal is brown, similar to our natural matrix opals. These opals have been treated to darken the ironstone and then stabilized to fill any small rough edges at the rear of the opal. The opals are then cut and polished normally like all our other opals.
We do not use any sealers, coatings or toxic chemicals in the process. The natural gem colors are not altered and are richer only due to the darker contrast of the ironstone. We pride ourselves in offering you boulder opal with bright gem colours. We go the extra mile to offer top quality opals in all price ranges.
