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, if I recall.
