What does Rock Crystal mean?

“Rock Crystals” come from the Greek word “krystallos,” which means ice or frost. This mineral was named because of its resemblance to ice when it is polished or cut into shapes.

The word “rock” is not part of the name, but it does refer to the fact that this mineral is found in rocks. This gemstone is a form of Quartz, which means it’s made up of silicon dioxide (SiO2).

The word “crystal” is used to distinguish it from other types of Quartz. They are semi-precious stones that have been polished or cut into shapes for jewelry and decorative purposes. They’re often used in carvings, sculptures, and other decorative items.

What’s another name for Rock Crystals?

The term “Clear Quartz” or “Crystal Quartz” is often used to refer to Rock Crystals. Some other common names include:

  • Alaska Diamond
  • Rock Candy
  • Alencon Diamond
  • Berg-Crystal
  • Mountain Crystal
  • Unripe Diamond
  • Vallum Diamond


Clear Quartz Crystals have been around for thousands of years. The earliest evidence of humans using them dates back to 3500 BCE when they were used in jewelry and other decorative items.

They have been found in ancient Egyptian tombs, and the Greeks and Romans used them for ornamental purposes. For example, the Great Pyramid of Giza contains over 2.5 million pounds of this gemstone.

In the 19th century, these stones were used for scientific research because of their ability to produce polarized light. Crystal Quartz was also used in gemology and jewelry making. Today, they are still prevalent in both industries.

The Ancient Greeks prized Crystal Quartz and believed it to be water frozen by the gods. So they used the material for seals and intaglios.

In Japan, Clear Quartz was considered “the perfect jewel,” embodying patience and perseverance, infinity in space, and purity.

In Ancient times, Native Americans used crystal hunting talismans by feeding them deer’s blood.

How are They Formed?

Water evaporates and leaves behind chemicals such as silica and other minerals that can’t be dissolved. These materials are then deposited at different depths within the earth’s crust.

When pressure builds up between these layers of sedimentary rocks, they become compressed into a solid crystal structure. This whole process takes millions of years to complete.

Where can you find Them?

Rocks crystals are found inside geodes, often in the same mines where agates, amethysts, and other gems are found. They are commercially mined in many countries around the world, including:

  • Afghanistan: Badakhshan, Khost, Nangarhar, Nuristan, Parwan, Zabul

Cost and Value

The price of a Crystal Quartz will depend on the specimen’s size, shape, and color. The cost to produce quartz crystals in today’s market is relatively low because they are not very difficult to extract from their natural environments.

  • Size: Price increases drastically with an increase in size as larger stones are harder to find and more difficult to cut. A small, clear crystal one or two inches in diameter will sell for $20 or less. The value of large crystals is hard to determine as they are extremely rare.
  • Quality: Quality is determined by the number of inclusions and imperfections in the gemstone. Clarity is also essential when determining the quality of a Clear Quartz. 
  • Cut: The cut of colorless gemstones like the Rock Crystal is the main determining factor of its price. As with all fine jewelry, the quality of the cut determines how beautiful and valuable it will be. The cut can make a massive difference in the price of specific stones.
  • The most common cut for a rock crystal is hexagonal, also known as a pyramid. It is also possible to find octagons and pentagons in some rare cases. The angles of the cut are vital because they affect how light reflects off the gemstone. The more precise the angles are, the more light will reflect into your eye and improve its appearance.

Crystal Quartz Appearance

Individual Crystals of Clear Quartz gems are transparent or white with a vitreous luster. Most have a hexagonal shape and six sides, but some have eight or more sides. Some also have flat faces that contain inclusions.

Some quartz crystals have a “star” shape, meaning they have six points that radiate from the center. The star shape is caused by hydrothermal fluids flowing through rock cracks and depositing silica around them.


The most common color for quartz crystals is clear or white. They can also have a slight pink, yellow, brown, or blue stain. Impurities color some rock crystal specimens, such as iron oxides or carbonates, in the material they are formed.

Some quartz crystals are tinted with tiny hematite inclusions, giving them a reddish hue. Other quartz crystals have been exposed to hydrothermal fluids containing iron and manganese, giving the rock crystal gems a blue or green hue.

How can you tell if it is Real or Not?

  • Acetone Test: Do an acetone test. Soak them in acetone for a couple of minutes to see if the color comes off. If it does, then it’s likely fake.
  • Transparency: Check the transparency. Rock crystal is a transparent gemstone. If it looks opaque, it is most likely a fake.
  • Scratch Test: Do a scratch test. Kitchen knives shouldn’t leave a mark on hard stones with a rating of 6-7 or higher. This crystal has a Mohs hardness of seven and does not have cleavage like other quartz varieties.

You can use a refractometer to determine whether the Clear Quartz is natural. This tool uses light and a lens to measure the gemstone’s birefringence, which is its ability to bend light through different indexes of refraction. The birefringence of a Rock crystal is 0.009.

If you don’t own a refractometer, you should take your gemstone to a jeweler shop to get it appraised. You can also take it to a gemologist.
