What Is Quartz?

Quartz is a mineral of silicon and oxygen atoms arranged in a crystal lattice structure. It has a hardness of 7 on the Mohs scale; as such, it is the hardest mineral known to man. It is highly resistant to chemical weathering and has a high thermal conductivity, making it a valuable industrial material.

 What makes this mineral so fascinating to gemstone lovers and spiritual seekers alike is its beautiful appearance and unique properties. It can come in various colors, shapes, and sizes, each with distinct properties and meanings. In addition, there are many varieties, each with unique beauty and benefits.

How is Quartz Formed?

Quartz is formed through the slow crystallization of magma, volcanic ash, or hydrothermal solutions. The process starts with silicon and oxygen compounds deposition in the Earth’s crust. Over time, these compounds form tiny crystals that gradually grow and interlock, forming a larger crystal structure.

 The exact conditions under which this mineral is formed can vary depending on the type and location. For example, the clear type is often formed in igneous rocks or hydrothermal veins, while amethyst is in cavities within volcanic rocks. Smoky Quartz, conversely, is created through the natural irradiation of colorless crystals, which causes them to turn brown.

 Formation of this mineral is a slow and intricate process that results in some of the most beautiful and valuable gemstones on Earth.

The word “quartz” comes from the German word “Quarz,” which in turn is derived from the Slavic word “twrdy” (meaning “hard”). The Slavic word was originally used to describe any hard mineral. Still, over time, it came to refer specifically to Quartz.

 The word “quartz” has been used since the mid-18th century and has become the standard term for this mineral worldwide.

Quartz Value and Price

The value and price of Quartz can vary depending on several factors, including its type, color, clarity, cut, and carat weight.

Color is one of the most important factors affecting value. Clear and colorless samples are the most valuable, followed by pink and purple varieties like rose and amethyst. Yellow to brown, such as citrine and smoky Quartz, are generally less valuable.

Clarity is also important, as samples with fewer inclusions have more value than those with many inclusions or blemishes. Inclusions can include fractures, bubbles, and other imperfections affecting the stone’s transparency and appearance.

Cut is another important factor affecting the value. A well-cut gemstone will have good proportions, symmetry, and polish, enhancing its beauty and value. It can be cut into many different shapes, including round, oval, pear, and emerald cuts.

Carat weight The value is affected by carat weight and clarity, with larger stones valued higher than smaller ones of equal quality.

Other factors that can affect the value include:

  • The rarity of the stone.
  • The quality of the mining location.
  • The quality of the lapidary work that goes into cutting and polishing the stone.

The value depends on several factors. The prices can vary widely depending on the specific stone and market conditions. 

How Can You Tell if Quartz Is Real?

There are several tests you can perform to help determine if a quartz gemstone is real or fake. Here are some common methods to verify the authenticity:

  1. Visual inspection: A real piece should have a consistent color and texture throughout the stone. Look for any air bubbles or other inclusions that could be a sign of a fake.
  2. Scratch test: It is a hard mineral and can scratch glass, but it cannot be scratched by steel or iron. It is likely real if you scratch a piece of glass with the Quartz, and it leaves a mark.
  3. Water test: Drop the sample into a glass of water. It should sink to the bottom if it is real.
  4. UV light test: Some fake pieces may fluoresce under UV light, while real ones do not. Shine a UV light on the stone to see if it glows.
  5. Heating test: The real piece is generally resistant to heat, so you can try heating the stone with a lighter or other heat sources. If it is real, it should not melt or change color significantly.
  6. Conductivity test: Some types of the fake may conduct electricity, while real ones do not. You can test this by placing the stone between two electrodes and checking for conductivity.

While these tests can help determine if a sample gemstone is real or fake, it’s always best to have the stone evaluated by a professional gemologist or jeweler.
