Mined out of a small metamorphic skarn, these iridescent "rainbow garnet" Andradites came on the market in 2002 and have not been equaled since. They are unique in all the world! Their look is unmistakable - superb, electric luster and mahogany color with razor sharp dodecahedral form. The largest crystal is 1.4 cm, accompanied by numerous smaller ones. Sadly, collecting is now prohibited at this Magnetite mine, so these are seldom seen and rarely available. A wonderfully aesthetic thumbnail. This was the finest that Jim Houran could obtain in a decade of building his collection of thumbnail gem crystals, which had a strong suite of garnets. It is contacted on back, complete on display face, and far better than any other I have seen for sale in many years.
