About this piece

Natural Koroit Boulder Opal, Blue Opal Window, Australian Specimen, 9.91g/49.55ct Natural Koroit Boulder Opal, Blue Opal Window, Australian Specimen, 9.91g/49.55ct

A beautiful and completely one-of-a-kind natural Koroit Boulder Opal from Queensland, Australia, featuring a striking blue opal window emerging from its rich, dark ironstone matrix.

Weight
49.55 carats / 9.91 grams

What makes this piece special is its character. The exposed opal has a soft blue to blue-green appearance, surrounded by a more vivid bluish halo along the edge of the window. Rather than intense play-of-color, this specimen stands out for its natural contrast, earthy patterning, and wonderfully organic form.

The stone has been polished while retaining the unmistakable character of the original boulder, making it an excellent collector’s specimen, display piece, or addition to an Australian opal collection.

Approx. Size: 1” long × 0.40” wide

  • Origin: Koroit, Queensland, Australia
  • Material: Natural Boulder Opal in ironstone matrix

Every Koroit Boulder Opal is created by nature with its own individual pattern and character, no two will ever be exactly alike.

You will receive the exact specimen pictured.

“Wills shop has been my favourite for years now. He cares about the customers, it really shows with the packaging. There is always a great selection and a reason to visit his store to build your collection or gift a friend. It's always a great experience and I'd recommend a visit. Thanks.”
