Rainbow Moonstone: Moonstone belongs to the Feldspar group. The traditional mining countries are India and Sri Lanka, where the most precious pieces with blueish rainbow reflection are found. Stones in orange, grey and brown are also used in jewelry. Because of its low hardness, Moonstone is sensitive to pressure and friction but nevertheless one of the most popular gemstones in silverjewelry.

Rhodochrosite: The stone belongs to the Manganese-Carbonate-Minerals and polished pieces can often be identified by their concentric agate-like rims (in lighter colour) on the rose-red stone. The name derives from greek rhodos =rose und chroma =colour.  It occurs mainly as thin layers in Manganese ore and is used for the industrial production of the metal. Most of the gem quality Rhodochrosite supply for the jewelry market comes from Argentina, where Rhodochrosite deposited in stalactites as manganese-saturated soakage and rainwater steadily dropped from the cave ceilings.

Rose Quartz: Rosecoloured variety of the mineral Quartz (SiO₂). The colour exists due to trace amounts of Titanium, Iron or Mangnese as well as natural radiation occurring close to the mineral (natural radiation creates clear Rose Quartz). The stone is rarely found in crystal form, only specimen from Minas Gerais/Brasil are known to show crystallized structure. Rose Quartz has always been positively linked to matters of love, harmony and the heart.

Ruby: A red Corund (Corund of other colour is called Sapphire), whose colour qualities derive from the element Chrome.  The Ruby was already mentioned in the old testament and is historically considered the „stone of love and life“. Since 1835 the synthesis und colour enhancement of natural Ruby is known and due to the rarity of this gemstone in high qualities it became a common process in jewelry production.

Ruby Zoisite: New Description Coming Soon!

Rutilated Quartz: Rockcrystal (SiO₂) with inclusions of the mineral Rutile, which crystallized in multitude of fine needles during the formation of the Quartz. Because of its golden brown colour and the optical effect of clear Quarz the Rutile-needles are often mistaken for Gold inclusions. Rutilated Quartz in our jewelry comes mainly from Brazil, which is known to produce the most beautiful rutile inclusions in SiO₂ such as perfectly symmetrical Rutilestars.
