2" Golden RUTILE SUNBURST Needle Crystals Epitactic on HEMATITE Brazil for sale
Availability: In Stock
The golden rutile on this specimen appears to grow directly out of the silver gray hematite in the middle - a formation called epitaxial growth. The effect this creates is similar to rays of sunshine streaming out from behind a dark cloud, and both the specimen and the sunbursts are equally magnificent. The rutile needles, which are the same mineral as is found in rutilated quartz, are thin, elongated, flattened blades, while the hematite is a flat, platy surface. This material is unique to the mines in Novo Horizonte. This is a highly extraordinary sample of this colorful material, with rutile needles longer than most specimens you see.
