Rose Quartz

Rose Quartz is the pink variety of quartz, which owes its colour to traces of titanium, iron or manganese, or to microscopic fibres of another mineral. The colour ranges from soft pale pink to intense pink and is usually translucent to opaque, with a glassy sheen. Rose quartz is widely used in jewellery and as a decorative stone.

Major deposits include Brazil, Madagascar, South Africa and the United States. The mineral occurs in pegmatites and hydrothermal veins. Its chemical formula is SiO₂ and its hardness is 7 on the Mohs scale. A rare variant is star-rose quartz, which may show asterism in polished cabochons due to fine inclusions of rutile.

Selenite

Selenite is a clear to translucent variety of the mineral gypsum (CaSO₄-2H₂O). 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.
