Nat Blue Opal From Peru

Natural blue opal from Peru—the country's national stone—is a rare, opaque to slightly translucent "common" opal famous for its rich, Caribbean Sea-like blue and blue-green colors. Unlike precious opals, it lacks a fiery "play of color," but is highly prized for its saturated hue, unique dark fern-like inclusions, and soothing, waxy sheen. 

 

Key Characteristics

 

  • Origin: Mined exclusively in the Andes Mountains of Peru.
  • Composition: It is a hydrous silicon dioxide mineraloid with a relatively high water content, making it somewhat delicate and sensitive to high heat.
  • Mohs Hardness: 5.5 to 6, making it suitable for gentle jewelry wear like earrings and pendants.
