A very sharp twinned crystal of the rare mineral amblygonite, complete all around. MUCH BETTER In PERSON - it has a pleasing straw yellow color, good luster, and lots of gemminess to the point where much of the twin is transparent in person. This is one of the sharpest such crystals that I have seen, and it is perched upon a smalle rcrystal which acts as a natrual pedestal. Again, BETTER In PERSON! 5.9 x 3.8 x 1.7 cm
