Rhodochrosite
Rhodochrosite is a manganese mineral known for its pink to deep red colour and often distinctive band structure. The mineral has a glassy luster and occurs in both translucent crystals and solid, striated formations. Rhodochrosite is valued as an ornamental stone and collectible because of its vibrant colour and unique patterns.
Major deposits of rhodochrosite include Argentina, South Africa, Peru, Romania and the United States (especially Colorado). The mineral forms in hydrothermal veins, often together with other manganese-containing minerals. Its chemical formula is MnCO₃ and its hardness is 3.5 to 4.5 on the Mohs scale.

Selenite
Selenite is a clear to translucent variety of the mineral gypsum (CaSOâ‚„-2Hâ‚‚O). It is known for its glassy to pearly luster and often fibrous structure. A common form is selenite, which has a silky luster and occurs in long, fibrous crystals. Despite its name, selenite has nothing to do with the element selenium; the name is derived from the Greek word for moon, because of its soft luster.
Selenite forms in sedimentary environments during the evaporation of seawater and is found in countries such as Mexico, Morocco, the US and Australia. It is a soft mineral with a hardness of 2 on the Mohs scale, making it easy to work by hand. Almost all selenite sold on the Dutch market is satin spar; however, selenite is a market-accepted sales name.
