The Rainbow Magic of Opal

For centuries, Opal has been a symbol of hope, inspiration, and creativity. Its unique play-of-color creates flashes of rainbow hues that seem to capture the aurora borealis within the stone, making it one of the most mesmerizing gemstones in the world.

Opal is composed of silica spheres arranged in a regular pattern. When light enters the stone, it diffracts off these spheres, creating the spectacular play-of-color that can include every hue of the rainbow. The size and arrangement of the spheres determine which colors are displayed.

Opal Facts

  • Opal displays a unique optical phenomenon called "play-of-color" - flashes of rainbow colors that change as the stone moves.
  • Australia produces about 95% of the world's precious opal, with the most valuable being black opal from Lightning Ridge.
  • Opal is composed of silica spheres and can contain up to 20% water, making it relatively soft at 5.5-6.5 on the Mohs scale.

The Spectrum of Tourmaline

Tourmaline is renowned for displaying more colors than any other gemstone. From the soft pink of rubellite to the vibrant green of chrome tourmaline, from the electric blue of Paraiba to the unique bi-colored watermelon variety, tourmaline truly offers something for everyone.

The wide range of colors in tourmaline is due to different trace elements present during crystal formation. Iron creates green and blue tones, manganese produces pink and red, while copper (in Paraiba tourmaline) creates the most sought-after electric blue-green colors.

Tourmaline Facts

  • Tourmaline occurs in more colors than any other gemstone, sometimes displaying multiple colors in a single crystal.
  • Watermelon tourmaline shows pink centers with green outer edges, resembling the fruit it's named after.
  • Paraiba tourmaline from Brazil displays an electric blue-green color that's among the most valuable in the gem world.
