Rutile on Hematite


A fascinating specimen of golden Rutile “needles” emanating from dark, mirror-like metallic Hematite. This relationship between Rutile and Hematite is referred to as epitaxial growth. Epitaxy: Growing a crystal layer of one mineral (Rutile) on the crystal base of another mineral (Hematite) in such a manner that its crystalline orientation is the same as that of the substrate. ( Parenthesis mine.) That very rare and unique crystal orientation is what makes this crystal growth and this specimen so unique and amazing. A beautiful piece!
