Boulder opal is a variety of precious opal which has an ironstone host rock forming naturally as a part of the gem. Often just a thin vein of precious opal is present. It occurs in a very few specific locations in Queensland, Australia. Fine opal is a secondary deposit filling cracks or voids in ironstone boulders. They are considered solid opals. They are cut incorporating the host brown ironstone as a part of the gem.
On a very few occasions, nature will create a picture we can recognize. These scenes are referred to as a "painting by God" in Australia. It measures 43.97x33.59x8.57 mm, and weighs 93.65 cts.
We are in a process of designing a suitable pendant to display this miracle of nature.
