Collection: Boulder opals

Boulder opal is unique to the mining fields of western Queensland where opal formed in the cracks, fissures and other voids in ironstone.

Boulder opal forms some of the most striking patterns and plays of colour which are further highlighted by the darker ironstone background. 

Boulder opal is steadily becoming more expensive as supplies shrink due to the rising costs of mining and meeting environmental approvals.
