@sutterco.minerals: One of my favorite color palettes: sage green on electric magenta. . Here’s why these DR Congo specimens are so interesting from a chemistry standpoint: • The Pink: Cobalt ions (Co2+) substitute into the calcite/dolomite matrix, creating that brilliant fuchsia daylight color. • The Green: Kolwezite forms as a secondary copper-cobalt carbonate hydroxide, growing in velvety botryoidal nodules directly inside the cobalt-rich pockets. . These specimens illustrate high-contrast, rare species chemistry at its absolute finest. . Check them out on my eBay. 🔗 in bio! . #rareminerals #mineralspecimens #mineralsforsale #crystaltok #crystalshop
