Check out this incredible "Benz Calcite", with distinct lines of golden chalcopyrite perfectly outlining the 3 faces of the calcite crystal.  This phenomenon creates a pattern akin to the Benz logo, where they get their trade name.  This is a high quality example of the occurrence, be sure to check the details on the video!
 
As with all of our minerals, no two pieces are alike, offering a truly one-of-a-kind gift for mineral collectors, Minecraft fans, geologists, and rockhounds alike. From Daye County, Hubei, China. Pictured on 1" x 1.5" acrylic base with mounting putty, included with purchase.
 
About Calcite
Calcite is a popular collectible mineral cherished for its diverse crystal habits, vibrant colors, and widespread occurrence.  Calcite is a common mineral found in sedimentary, metamorphic, and igneous rocks worldwide.  It crystallizes in the trigonal crystal system, forming rhombohedral or scalenohedral crystals with three cleavage planes that are often visible.
 
Calcite is a major component of limestone, marble, and chalk, as well as many other sedimentary rocks. It also forms in hydrothermal veins, as a precipitate from groundwater, and as a component of some igneous rocks.  Calcite has numerous industrial applications, including as a building material (limestone and marble), in the production of lime and cement, as a soil conditioner, in the manufacture of glass and ceramics, and as a source of calcium carbonate in dietary supplements.
 
About Chalcopyrite
 
Chalcopyrite is a captivating mineral sought after by collectors for its dazzling metallic luster and distinctive brassy gold coloration.  It forms in a variety of crystal habits, from granular masses to distinct tetrahedral or dodecahedral crystals, often exhibiting iridescent hues of purple, blue, and green, caused by surface oxidation. 
 
This mineral is a significant source of copper ore and is commonly found in hydrothermal veins alongside other sulfide minerals such as pyrite and sphalerite.  In fact, we often refer to it as pyrite with a copper molecule added.  They are commonly mistaken for each other and can be difficult to distinguish when they are found in geologic occurrences together.
