RAREST ORANGE IMPERIAL TOPAZ

From our selection of collectible minerals we propose a rare Topaz crystal from Thomas Range, Utah. Furthermore, it is characterized by a gem-bearing crystal of intense orange color, in a shade reminiscent of precious imperial topaz, set within a small quartz druse on rhyolite host rock and reported as fluorescent, elements that enhance its aesthetic value and mineralogical importance. The specimen stands out for the quality of crystallization and for the overall aesthetic balance, with features that enhance its natural structure and visual impact. Topaz is an aluminum silicate nesosilicate with the formula Al2SiO4(F,OH)2 that crystallizes in the orthorhombic system; the orange-sherry coloration is related to lattice defects (color centers) and, as often happens with this species, may fade with prolonged light exposure. The Thomas Range area in Utah has been known since the 19th century for topaz crystals that form in small cavities within rhyolitic rock originating from intense volcanic activity a few million years ago. The most intense and gemmy tones, such as that of this small crystal, are sometimes associated with the precious imperial topaz, a variety traditionally linked to Brazilian deposits. This is an ideal specimen for mineral collections, display, and for those who appreciate the natural beauty of minerals, also in the context of crystal therapy and lithotherapy, according to the properties traditionally associated with the mineral species. All minerals are 100% natural and untreated, with extremely rare exceptions always noted in the description. Photos are taken with professional lighting to best enhance colors and details; however, slight tonal variations may occur depending on the device or ambient light.
