What affects the value of Rough Quartz Crystals?

• Clarity and transparency of the crystal, with water-clear 'Rock Crystal' specimens often fetching higher prices.

• Check for the characteristic hexagonal prism shape and pyramidal terminations typical of natural quartz growth.
• Verify the hardness by ensuring the crystal can scratch glass but cannot be scratched by a steel knife.
• Look for natural inclusions or internal fractures that distinguish genuine earth-mined quartz from synthetic glass imitations.
