These are good blue crystals with striated sides and black Biotite Mica on them. Most of the Kyanite crystals from the Karoi pegmatites are grey to grey blue, but these are distinctly blue to deep blue with some translucence in them. It has been a while since we stocked these, as they are not always available and are mined very sporadically.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePRODUCT DESCRIPTION\u003c\/strong\u003e\u003cbr\u003eKyanite is an aluminium silicate mineral that forms in high-pressure metamorphic rocks.
