Physical properties
Tiny, vivid blue, translucent fragment with a reflective surface; hardness, cleavage, and crystal structure cannot be determined from the image. Its appearance could also be manufactured glass or another blue mineral.
Formation & geological history
If topaz, it formed in silica-rich igneous rocks or associated pegmatites and hydrothermal veins; geological age depends on the deposit.
Uses & applications
Gem-quality topaz is used in jewelry and as a collector mineral; this fragment is too small to assess for practical use.
Geological facts
Blue topaz is commonly produced by irradiating and heating pale or colorless natural topaz.
Field identification & locations
The image is insufficient for reliable identification; inspect under magnification and test hardness, or have a gemologist examine it. Topaz occurs in Brazil, Pakistan, Russia, and other regions.
