A botryoidal crust of brownish-black goethite is host to a large, aesthetic cluster of lustrous and translucent, bi-colored manganoan adamite crystals, to a very LARGE SIZE of 3.5 cm in length. The lower 80% of the crystals are ivory-colored while the gemmier terminations exhibit a lovely, light lavender color. This is one of the largest clusters of manganoan adamite I have seen from the incredible finds at Mina Ojuela in 1981-2. Although the color is not intense, it is present, and in this case it is present as an accent to the overall form and richness of the piece, lending purple highlights to unusual white crystals. The crystals are sinuous and interesting, in and of their own. The contrast of the curving crystals which are sharply pointed on either end, with the rolling black hills of goethite matrix, really adds a lot to the specimen
