What Is Natural Rough Aquamarine Worth?

The typical price range for Natural Rough Aquamarine is $45 - $50 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

  • Color saturation: Deeper blue tones significantly increase the value beyond the $45-$50 range.
  • Clarity and transparency: Specimens with fewer internal inclusions or 'veils' command higher prices.
  • Crystal integrity: The presence of well-defined, undamaged hexagonal terminations increases collectibility.
  • Size and carat weight: Larger raw specimens of Beryllium Aluminum Silicate are valued more highly by mineral collectors.

How to Identify Natural Rough Aquamarine?

  • Verify the signature light blue to blue-green hue characteristic of the beryl family.
  • Look for a hexagonal (six-sided) crystal structure which is typical for raw Brazilian aquamarine.
  • Check for a vitreous (glass-like) luster on the surface of the uncut specimen.
  • Confirm the origin as Brazil, as these specimens often feature distinct clarity compared to African or Pakistani deposits.

History of Natural Rough Aquamarine

Aquamarine has been cherished for centuries as a talisman for sailors, believed to protect them at sea. Its name is derived from the Latin 'aqua marina' meaning water of the sea. Large deposits were historically found in Brazil, though significant mining now occurs in Pakistan and parts of Africa.
