Item Description
Intergrown, lustrous, sharp, rutile after brookite crystals from the famous Magnet Cove area. The well-striated crystals are metallic-gray and have textbook orthorhombic form. Some of the crystals are twinned. One side is contacted, but this remains a showy and highly representative example. This mine was active from 1934 to 1944. Probably older material from the mining period. Ex Bob Trimingham Collection.
