Ophir Mine, Tooele Co, Utah
    Although Scheelite is the predominant ore mineral of Tungsten, it is usually massive and indistinct from its matrix, except under shortwave UV light, when it reveals itself to be in that elite group of minerals that always fluoresces. As a crystal, however, it is extremely scarce, and when found in this form, they are usually widely scattered and/or embedded in matrix. Even when found together, they are usually in small, sparse clusters, or at best, thin veinlets. However, the Scheelite of the Ophir Mine is perhaps unique in the world, found in large faces of micro-crystals, and these specimens were an instant smash hit when introduced onto the market in the late 1990s. They comprised a small find of only a few dozen specimens, but there were quite a few with large and well-covered faces. The crystals typically fluoresce blue-white under shortwave rays, but will occasionally display a soft creamy color also, due to a greater percentage of Molybdenum. This specimen is one of the very best examples of this much scarcer type, 6ΒΌ x 5 x 3 inches (15.7 x 12.7 x 7.6 cm), with the main face almost completely covered with brilliantly fluorescing blue-white and cream-white crystals.

    Provenance: ex. Hugh Ronemus Collection
