This very rare copper, zinc, phosphate, reaches its worldwide zenith in Montana. Or it did, anyhow, over 30 years ago! Such specimen are extremely rare and this is a HUGE crystal for the species, at the top of its size range except for a few freak outlying specimens. This cluster of extremely lustrous, rich and deep blue green veszelyite crystals, perched vertically on a small white quartz, is quite simply phenomenal and the best such I have had for sale. In person, it is much more 3-dimensional, and colorful as well. The blue is dark, true, but it IS a vivid blue color and not as dark as it looks in the photo. This is a very rare specimen of highest quality that ALSO happens to be a superbly balanced thumbnail specimen for the collector.
