- Hydroxylherderite on Feldspar
- Virgem da Lapa, Minas Gerais, Brazil
- Large Cabinet, 23.4 x 12.5 x 5.0 cm
From a new find, these unusual matrix herderites are really interesting for the stark contrast to matrix they seem to just "pop" out of. This large feldspar crystal has an inset single crystal of lavender-colored herderite, 3.4 x 3 x 2 cm in size. The crystal is fairly translucent even in normal lighting but glows more colorfully with even just a bit of backlighting. It is complete and undamaged. A very nice specimen from a novel find at a new locale in this area. Note that these just came out, and I am throwign on the web "as is." Obviously, trimmed up a bit, this could size down to a killer small cab. As is, though, I thought it a shame to break such an unusual feldspar crystal just to make the overall piece smaller so it fits in more specimen cabinets.
