Smoky Quartz Gemstone Information

Smoky Quartz Introduction
Smoky Quartz stands out with its deep earthy shades and grounding qualities, making it a gemstone appreciated for both its appearance and its reputed metaphysical attributes. From early societies to today's crystal fans, people have valued Smoky Quartz for its potential to shift negative energy toward positive ones and foster feelings of steadiness and safeguard.
The quartz group features well-known members like Amethyst, Citrine, Agate, Jasper, and Rose Quartz. As you can tell from these, quartz shows up in an impressive variety of hues and designs.
Quartz ranks as one of the most abundant minerals on the planet - think desert sands, mountain granite, igneous rocks, and volcanic lava. It's practically everywhere!
Our focus here is on the quartz suitable for gemstones, which falls into two categories:
- Macro-crystalline: These are big, easily recognizable crystals, often clear with defined edges and pointed tips.
- Micro-crystalline: These consist of small, tightly packed crystals that tend to be opaque and rounded.
Smoky Quartz belongs to the macro-crystalline type, typically fully transparent with rich, grounded colors.
Smoky Quartz Colors

True to its name, Smoky Quartz appears as a darker stone, spanning from a pale grayish brown to nearly black.
Impurities during its creation cause this coloring, and based on the minerals involved, it might show yellow, amber, or red hints - sometimes likened to coffee, honey, or caramel, depending on who's describing it.
When it comes to value in this affordable gem, it really boils down to personal taste, as all brown variations hold comparable worth.
Smoky Quartz Species
Most brown quartz simply goes by Smoky Quartz, but two notable varieties have earned recognition, even though they're identical in chemistry and structure to standard Smoky Quartz.
- Cairngorm Quartz: This yellow-brown type hails from Scotland's Cairngorm Mountains and occasionally gets called Scotch Topaz, tying into local fame.
- Morion Quartz: A very dark, near-black version said to result from natural radiation - safe to handle, though not always authentic.
Smoky Quartz Clarity and Cut

Smoky Quartz gems usually boast top-notch clarity. While some might have inclusions or haziness that appeal to certain tastes, you can easily find pieces with perfect transparency.
This sturdy gem comes in various shapes and cuts - beginners in gem cutting often start with it due to its low cost and ease of working.
As a clear stone, faceting enhances its sparkle best, but cabochons offer a smooth, domed style for a retro feel, and carvings into shapes like flowers or animals add creativity.

Smoky Quartz Discovery

The term Quartz traces back to German "Quarz" and Polish "Kwardy," both meaning hard. Humans have used quartz for tools, decor, jewelry, and spiritual practices for millennia.
"Smoky Quartz" entered gem terminology in 1837 via mineralogist James Dwight Dana, named for its smoke-like hue.

Family standouts like amethyst, citrine, and rose quartz appear in records from Ancient Egypt and Greece.
Romans carved them into seals for documents, Sumerians made cylinder seals earlier, and in China, thin Smoky Quartz slices served as early sunglasses.
Smoky Quartz linked closely to Celts and Druids, featured in Samhain festivals marking harvest's end. Today, it graces Scotland's Crown Jewels and a massive one resides at Balmoral Castle, bought by Queen Victoria.
Where is Smoky Quartz Found?

Smoky Quartz appears worldwide, but top specimens come from Brazil, Madagascar, Russia, and Scotland - where it's the national gem.
How is Smoky Quartz Formed?

Quartz often forms in pegmatite, an igneous rock from slow-cooling magma. As it cools, fissures fill with fluids and gases that crystallize into gems over time.
Added elements during this process influence color - aluminum yields smoky tones, iron creates amethyst's purple or citrine's yellow.
Darker Smoky Quartz sometimes ties to nearby radioactive minerals, but it's safe to touch.
Can Smoky Quartz Be Treated?
Usually, Smoky Quartz only gets cut and polished from its raw state, without further enhancements.
Some undergo irradiation to mimic natural dark shades from radiation, but that's rare given the cost for such a low-priced gem. Others might be heated to lighten color - decisions, decisions!
At GemSelect, we disclose any treatments on our gems.
