- Rutile, Brookite, Quartz
- Miniature, 4.4 x 4.3 x 2.0 cm
- Diamantina, Jequitinhonha valley, Minas Gerais, Southeast Region, Brazil
An excellent specimen of two, intergrown, angled, water-clear quartz crystals richly filled with brilliant, silvery rutile needles and red brookite blades from Diamantina, Brazil. This is very fine two-sided material, that looks like a Japan-law twin, but is not, as the crystals are intergrown. The combination of rutile and brookite included in quartz is very uncommon from Diamantina.
