Bixbyite on Topaz
2.6 x 2.2 x 1.7 CM (thumbnail)
Bixbyite crystals with some complex faces up to 1.4 CM across on contrasting Topaz crystals. The Topaz is heavily included as is typical and several of the Bixbyite faces have a dusting of micro Topaz which are very clear. A very nice representative thumbnail of this classic locale. Some chipping seen with magnification mostly on edges, some crudeness to crystals too but still lustrous and sizable.
Bixbyite, Pseudobrookite & Topaz
Thomas Range, Juab County,
4.6 x 3.4 x 2.8 CM (miniature)
Post Tucson 2015
From the Thomas Mountains a multi-species specimen with nice esthetics. This could be trimmed to thumbnail size but I like it as is. Fine condition, although with magnification some small contacts are noted on the Bixbite. It is not common to see all these species on the same matrix in close proximity.

2.9 x 2.7 CM (thumbnail)
A lusterous thumbnail with several sizable and sharp bixbyites, on a matrix of topaz (cystallized with "sand" inclusions). The crystals all have some contacting and included topaz and the matrix topaz is somewhat crude. Despite this the largest crystal of Bixbyite is sizable at 1.4 CM and very bright, and this is well over the average in general quality.
