What on Earth Is Smoky Quartz?

What on Earth Is Smoky Quartz?

Smoky Quartz is one of the coloured varieties of Quartz together with Amethyst, Citrine, Rose Quartz, Lemon Quartz, and Ametrine. Its colour ranges from yellowish brown to a dark brown that is almost black. Some specimens can have a grayish brown hue. When cut into gemstones, those with an orangey brown to a reddish brown colour are highly sought after.

The Physical Properties of Smoky Quartz

It occurs as druzy or masses of hexagonal translucent (sometimes opaque) crystals in igneous and metamorphic rocks. It often contains inclusions of solids (rutile), liquid (water and liquid carbon dioxide), or gas (carbon dioxide).

Smoky Quartz gets its colour through natural and artificial means. In natural settings, radiation emitted from surrounding rock activates the colour centers around the aluminum impurities in the crystal. Alternatively, Quartz crystals are irradiated in a laboratory to create various shades of brown. Although this is not often done since natural Smoky Quartz is abundant in nature and is relatively inexpensive.

With a Mohs hardness rating of 7, Smoky Quartz is a durable crystal with a glassy luster. It forms a smooth conchoidal fracture when exposed to pressure. It is often faceted or cut into beads and cabochons for use in various jewelry pieces. Smoky Quartz is also a popular material for carving.

The History of Smoky Quartz

The name Smoky Quartz was first heard of in the realm of gemstones in 1837. It was reported by mineralogist James Dwight Dana who named the brown Quartz crystal as such due to its semblance to smoke.

Scotland is the country known to have a wealth of historical associations with Smoky Quartz. This is why Smoky Quartz is the country's national gem.

Colonizing the British Isles sometime in 300 B.C., the Celts mined Smoky Quartz in the Cairngorm Mountains of the Scottish highlands. They classified the brown to black crystals as Morion, while the yellowish brown to grayish brown crystals are called Cairngorm.

Later on, the crystals became popular ornaments for Highlander apparel. Smoky Quartz were used in brooches and kilt pins. It was even used as power stones placed on the handles of weapons like the Scottish dagger called sgian dubh, a sock knife which is part of Scotland's kilted dress uniform.

Smoky Quartz can be found everywhere in the world. But the finest specimens are found in Australia, Africa, Brazil, Madagascar, and the US.
