Return to Gemstone Spheres
This Opal Butte Opal sphere is large, very attractive, and a great collectors’ item.
Opal Butte Opal occurs inside nodules, or thunder eggs, and it is mostly known for its wonderful colors. It took a very large thunder egg to make this sphere.
Most of the sphere consists of the thunder egg matrix (rhyolite). However, there are two windows of colorful (some yellow, orange and a little blue) and some clear opal.
There is also a section of particularly beautiful common opal (peachy cream color) with a bluish lining, cracked egg shell patterns, and some brownish yellow dendrites.
There is some fire in various sections and small rainbows. The matrix itself is a very nice and colorful rhyolite (some mixed with opal) with interesting patterns.
