Smoky Quartz Crystal Overview

Like other quartz gems, the Smoky Quartz crystal is a silicon dioxide crystal. Its smoky color results from free silicon formed from the silicon dioxide by natural irradiation. Iron inclusions within the crystal cause deep brown or gray coloration.

Smoky Quartz was referred to as Cairngorm after the Cairngorm Mountains in Scotland’s highlands, where it was found initially. This article will take a look into the properties, meanings, and uses of the Smoky Quartz crystal.

What Is Smoky Quartz?

Smoky Quartz crystal is a type of quartz characterized by its brownish color. The word “smoky” refers to how the stone looks when it’s held up to the light, which creates an effect that makes the stone look like smoke rising from within it.

Smoky Quartz is a popular stone for jewelry, but it’s also been used for centuries in other ways. For example, ancient cultures in China used this gemstone to make sunglasses.

The Chinese believed that this gem could protect the wearer from ghosts and evil spirits, so they made sunglasses out of it. These sunglasses were worn by people traveling or working outside at night because they believed they would help them see better in the dark. The Chinese also believed that wearing a Smoky Quartz crystal would help prevent eye diseases like glaucoma and cataracts.

Today, this stone can be used for many different purposes. For example, it has been said that wearing or carrying a Smoky Quartz crystal will bring clarity into your life. Additionally, if you need help finding a lost object or person nearby, placing one near where it might have gone missing will do just what you’re looking for!

Smoky Quartz crystal Appearance

  • Smoky Quartz is a brownish-gray, translucent variety of quartz. It ranges from almost complete transparency to an almost opaque brownish-gray crystal. 
  • Some can also be black. Most specimens will show some degree of smoky or cloudy markings when viewed under magnification.
  • The smoky color results from free silicon formed from the silicon dioxide by natural irradiation. Free silicon is a dark brown or black color, and it’s found in quartz crystal. 
  • Smoky Quartz is a type of quartz recognized for its beautiful color, ranging from dark gray to golden brown. However, it takes a lot of time for this type of Quartz to form naturally because it requires exposure to radiation for millions of years before looking like its current state.
  • This stone is also known as smoky citrine and cairngorm because it resembles the yellowish-orange semi-precious stones of those names. However, it’s not actually either of those gems: it’s a type of quartz crystal!
  • It’s not always easy to tell the difference between Cairngorm Quartz and other types of Quartz. However, a shiny surface is one way for you to distinguish smoky quartz from others.

How To Tell If A Smoky Quartz Is Real?

Before you purchase any stone, it’s essential to know how to tell if it’s real. Quartz is one of the most common minerals on earth, making up about 12% of the crust in terms of volume. However, only a small percentage of Quartz is smoky, which makes it much harder to find than other types of clear or white Quartz.

To test whether or not your Smoky Quartz crystal is genuine, try the following:

Scratch Test

Use a scratch test by making a small mark with a mineral that is lower on the Moh’s scale, such as glass or obsidian. A genuine Smoky Quartz crystal will be unaffected, while a fake crystal will get scratched.

If there are visible marks, this indicates that what you have might be glass or synthetic material instead of natural crystal with impurities included within its structure.

Sunlight Test

For the sunlight test, you will need to expose your smoky quartz crystal to direct sunlight for 24-36 hours. 

Natural crystals will retain their color despite their exposure to sunlight. If the crystals start to fade and lose color, it is an indication that they are probably fake. 


This test is used to ensure that a piece of smoky quartz is not just dyed glass. Place your crystal over a book or a page with words. Natural smoky quartz will not magnify the words. If the words appear slightly larger, you are likely in possession of a fake crystal.

Physical Properties

An easy way to understand the physical properties of a gemstone is by using the Mohs scale. The scale was created by German mineralogist Friedrich Mohs in 1812 and it’s used to measure hardness based on the ability of one material to scratch another.

Smoky Quartz has a hardness between 7 and 7.5 on this scale—softer than topaz but harder than jasper or obsidian—and because it belongs in this range, it can be scratched with other stones that are also within its scope of hardness, including tourmaline, quartzite, and amethyst (all scoring 7-7.5).

Smoky Quartz Value

Smoky Quartz is considered a semi-precious stone, which means it’s not as valuable as precious stones like diamonds. However, it can still be quite valuable due to its rarity and excellent qualities.

The price per carat will depend on the size of your stone, how well it’s cut, and its quality.

Size: The size of your gemstone will have a direct impact on its value. Generally speaking, larger stones are more expensive than smaller ones; however, if they’re cut poorly, they can lose their value quickly!

For example, a one-inch long oval-shaped stone would cost $30-$50 per carat, while an 8mm round gem would cost $35-$60 per carat based on current prices at Midwest Gem & Mineral Society (MGMS).

Quality: Quality also plays a considerable role in determining the price point for this semi-precious stone.

For example: If you have two identical pieces of smoky Quartz, but one has been polished while the other hasn’t been touched yet, then only one might be worth hundreds more dollars than another just because it has more clarity (and therefore better color).

How To Take Care Of Smoky Quartz crystal?

  • Smoky Quartz is a very durable gemstone, but it can still be scratched. Store it in a cool and dry place to avoid damaging the stone. 
  • Refrain from using hot water or steam cleaners on your smoky quartz jewelry because they may cause permanent damage to the stone. 
  • When you clean your jewelry, use lukewarm soapy water and wipe gently with a microfiber cloth to avoid scratching it further. 
  • If any streaks are left behind after washing, rub them away with another soft cloth before drying thoroughly with a dry towel. Let it air dry, so no moisture remains inside the crystal after cleaning.
  • After cleaning your Smoky Quartz pieces with lukewarm soapy water, burn white sage or other cleansing materials nearby to remove any excess negative energy from them.
  • This will prevent them from losing their energy over time and keep you safe from any negative energy that could leak into your own body when you wear them.
