White Quartzite Value Guide

White Quartzite is a nonfoliated metamorphic rock formed from sandstone through intense heat and pressure, dating back as far as the Precambrian era. Its enduring popularity among collectors stems from its high quartz purity and its historical significance in both decorative and industrial applications.

What Is White Quartzite Worth?

The typical price range for White Quartzite is $30 - $30 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Purity of the white color, with brighter and more consistent specimens commanding higher interest.
• The size and structural integrity of the crystal, as larger, uncracked pieces are more desirable for display.
• Historical or geological provenance, particularly specimens originating from notable Precambrian formations.
• The quality of the surface finish, whether it remains in a raw natural state or has been polished to highlight its crystalline structure.

How to Identify White Quartzite?

• Look for a nonfoliated, granular texture that distinguishes it from the layered appearance of marble.
• Verify the opaque white color, which indicates a high concentration of pure quartz with minimal mineral impurities.
• Test for hardness; authentic quartzite will easily scratch glass and cannot be scratched by a steel knife blade.
• Examine the fracture pattern, which typically breaks across the quartz grains rather than around them.

History of White Quartzite

Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz. It forms from sandstone and can be found in various colors depending on the impurities present. White quartzite is highly prized for its aesthetic appeal and durability, making it a popular choice for both decorative and industrial uses throughout history.
