Info: Rhodochrosite is often found in grain or whole agregates. It is opaque, with pink, purple or yellowish colour. Rhodochrosite have glassy to pearl shine, which is often covered in the agregates forms with a black-brown layer of manganese oxide. Good developed crystals are rare but...
Info: Good developed crystals of smithsonite are liked by the collectors. Smithsonite is found in little trigonal crystals, sometimes curved. Good developed trigonal crystals are rare. Common smithsonite is found in agregates with different shapes. It can be colourless or white, but often is...
Info: Siderite crystalizes in trigonal crystals, often curved. Crystals of siderite are rare. His colour is pale yellow to brown. When the siderite have more manganese in his formula, he is darker. Siderite is translucent to transparent, with glassy to pearl shine. This mineral is relatively...
Info: Magnesite is from the calcites group and crystalizes like them, in crystals with trigonal structure. His cristals are simple and doesn't make so complicated forms like some other calcites. Magnesite is most commonly found in grain masses with white-grey colour, which are opaque....
Info: Witherite commonly crystalizes in triple pyramid-like crystals. The agregates of whiterite are common too. Whiterite is in most cases colourless, white or grey, but it can obtain colours like yellow, green and brown too. The mineral is from translucent to transparent, with glassy to oily...
