Haiweeite, Gypsum (Var: Selenite) from Perus, São Paulo, São Paulo, Southeast Region, Brazil [db_pics/mdpics/MD-169928a.jpg]

6.5 x 5.0 x 1.5 cm. This rare and colorful uranium mineral is emplaced on matrix with contrasting white selenite and features glassy, translucent, lemon yellow crystal sprays reaching 6mm across amidst the selenite. It is a very attractive, high quality specimen from this locality which has produced best of species so far as I know. Carlos Barbosa brought most of them out in the late 1990s and only rarely does a good piece turn up on the market nowadays.

6.5 x 5.6 x 1.9 cm. Haiweeite is one of the more attractive of the non-African suite of radioactives containing uranium, and remains a rarity known in good crystals from but a few locales. This is a very rare, hydrated, calcium, uranium, silicate. Extremely colorful and rarely ever seen in dealers stocks. This is a large and rich specimen of the material. It came out about 6 years ago.

Extremely colorful and rarely ever seen in dealers stocks. This is an extremely large and rich specimen of the material. It came out about 5-6 years ago.
