Royal Blue Sodalite

Discovered in 1811 in the IlÍmaussaq intrusive complex on the south-west coast of Greenland, royal blue sodalite is distinguished from similar minerals by its white streaks. Nowadays, the Ice River Complex near Golden in south-eastern British Columbia, Canada, is an important deposit for mining.

Cobalt Calcite

This pink, cobalt-containing variant of calcite is less common than the standard white version, which certain geologists have come to refer to as a “ubiquitous mineral”. It can be found in Peru and the Katanga Copper Crescent of the Democratic Republic of Congo.

Jasper Quartz

A textural variety of quartz, jasper is typically found in the veins and cracks of volcanic rocks, which form during vigorous tectonic activity. It is common across the planet, particularly in this reddish hue, with notable deposits in India, Madagascar, Australia, Venezuela and Uruguay.

Almandine, which abounds in the gem gravels of Sri Lanka, belongs to a group of closely related minerals known as garnets. All garnets are isomorphous, meaning they share a molecular arrangement, but their specific elements differ, hence their wide spectrum of colour.

Himalayan Quartz

Mined by hand in the uppermost reaches of the planet’s tallest mountain range, Himalayan quartz is transported downhill by the hardy native yak. The deposits near the Tibet/Nepal border are thought to be the oldest on earth but were revealed relatively recently by glacial recession.

Iron Pyrite

Referred to as fool’s gold because of its superficial resemblance to the precious metal, iron pyrite nevertheless forms in neat cubes or multifaceted crystals, whereas native gold is anhedral or irregular in shape. Notable occurrences are found in the American state of Illinois and La Rioja in northern Spain.

Calcite Crystal

The largest documented single crystals of calcite are found in Iceland, where some examples have been known to weigh around 250 tonnes. The gleaming mineral can also be admired in spectacular form inside the Snowy River Cave stream bed in Lincoln, New Mexico, USA.
