Item Description
This rare earth oxide is not a valid species, but rather a variety of Rutile. It is closely related to Ilmenorutile, however the presence of Tantalum makes for a very unique chemistry. This piece features a moderately sharp, well formed, dark brownish-black crystal of "Struverite" measuring 1.9 cm on massive translucent Quartz matrix. These specimens are no longer being found, and this pieces features one of the best quality crystals of this material that I've seen. Do NOT miss out on this one, as it is the best I have left to offer from Madagascar. Valued at $700.
