Boulder Opal Tumbled Stones

Boulder Opal Tumbled Stones

Boulder Opal is a natural opal found within ironstone host rock, primarily from Queensland, Australia. It displays flashes of colour (play-of-colour) against a dark ironstone matrix, making each stone visually unique.

In crystal tradition, Boulder Opal is associated with inner reflection, spiritual connection, and communication. It has long been used in ceremonial practice by indigenous peoples and is said to support clarity of expression and connection to spiritual guidance.

Approximately 2–3cm per stone. Priced per individual tumbled stone. Colour, patterning and play-of-colour will vary.
