Natural Australian Boulder Opal 13.35ct Freeform Loose Gemstone

Discover the natural character of this Natural Australian Boulder Opal 13.35ct Freeform Loose Gemstone, featuring an organic shape that showcases the distinctive appeal of Australian Opal.

Australian Boulder Opal forms within ironstone rock, often retaining part of its natural host rock alongside the Opal. This combination can create fascinating contrasts in texture, colour and pattern, making each piece individually distinctive.

The freeform shape preserves an irregular, organic outline rather than following a standard cut, making it an appealing choice for unique jewellery projects, gemstone displays or collector’s collections. Weighing 13.35ct, this piece offers plenty of character for those who appreciate natural Opal specimens.

As a natural gemstone, Boulder Opal can vary in colour, pattern, ironstone content and the presence or intensity of play-of-colour. These characteristics differ between individual stones and contribute to their unique appearance.
