At least 4 different formations of Rutile twins make up this small thumbnail specimen. These crystals take on the form of the popular "star" twin- though none are more than two-thirds complete- and are generally in good condition, though a few twins are heavily damaged. The Rutile needles reach lengths of up to 0.4" (1.0 cm) and are heavily intergrown, so that their tetragonal bladed form is difficult to study. All have the classic golden color and almost silky metallic luster of their species. They extend from bases made out of hexagonal hematite blades, most of which are broken and nearly formless. There is no host rock present, and the piece is affixed inside a plastic specimen box with an adhesive putty.
