For decades the mineral was known almost exclusively in a cloudy, opaque form — facetable, clear material remained the exception and still comes almost entirely from southern Madagascar. Cut stones above one carat count as a rarity among collectors.\u003c\/p\u003e\n\u003cp\u003eIts colour lies between blue-green and green-blue and comes from iron in the crystal lattice. The pronounced trichroism is striking: depending on the viewing direction, the same stone appears colourless, blue-green or dark green.
