WOW! Super-sharp single "triangular" crystal 4.6 cm tall resting on a small amount of matrix, and also slight contacted at the top. The glassy luster and superb clarity make this a killer miniature. You do not often find vivianites this thick (almost 1.5 cm) to be so glassy and clear. Minor matrix inclusions are in the termination, but they do not affect its sharpness, especially from the front. A definite keeper and one of the best darned deals in the whole batch!
