A large and dominant specimen of adamite on brown limonite gossan matrix that is absolutely rich with sparkling and glassy adamite! There are actually two different types of adamite present. The larger aggregate on the left half consists of tightly packed lime green adamite. A smaller aggregate on the right half shows a darker yellow color that looks incredibly similar to legrandite. As a matter of fact, we bought the piece with a label that says “adamte, legrandite” but which ultimately proved wrong in our examination. The whole specimen is all naturally developed with a crystallized backside. There is some minor damage at the upper part of the lime green adamite but most of which is older, not freshly broken.
