一个真的、非常怪异且异常巨大的钴方解石漂浮标本，来自这个经典的刚果产地，以钴矿物和铜矿物而闻名。这件作品，尤其，是来自最近相当新发现的产物，我没有找到太多信息，也没看到太多同类，因此很可能来自一个相当小的空腔。尽管如此，就尺寸而言，这件作品已经很了不起，因为很少有钴方解石的晶体能达到如此之大，并且它的晶体也非常完整晶莹。该标本由两个互生、锋利、光亮、界定清晰的菱方晶组成，外表呈深勃艮第紫色，内部则是无色的普通方解石，通过周围的一些剥离处可以看到。也有可能这意味着分布在外部的钴富集区代表外部带状分异，或者是方解石表面的部分置换显现。该件表面可见孔雀石与异源矿（heterogenite），其中孔雀石因其鲜明的色彩对比而显得格外美丽。）

A really, really odd and remarkably big cobalt calcite floater from this classic Congolese locality, famous for both cobalt and copper minerals. This piece, in particular, comes from a fairly recent find, which I have not found too much information about nor seen too many pieces from, so it probably was a pretty small cavity. Still, this piece is already remarkable just size-wise, as not many cobalt calcites are found to have crystals nowhere near as big, and also, it is just so well crystallized. This specimen is composed of two intergrown, sharp, lustrous, and well-defined rhombohedrons with a deep Bordeaux purple-colored exterior and a colorless normal calcite interior that shows through a few exfoliations found around the piece. This either implies the cobalt-rich exterior represents an external zonation or it is a partial replacement of the surface of the calcite showing through. On this piece's surface, both malachite and heterogenite can be observed, with the malachite being of particular beauty thanks to its striking color contrast.
