AI-assisted summary
Description from the seller
The Boulder opal in the image is a unique example of opal formation in ironstone (boulder). The opal shows an intense play of color with vivid reds, greens, blues, and violets, embedded in a gold-brown, iron-rich stone. Boulder opals form in cracks and fissures of iron-rich rocks, where the opalescent material deposits. The image shows how the natural matrix of ironstone threads through the opal seam and highlights the glowing colors of the opal.
The structure is typical for Boulder opals, as the opal layers are often irregularly distributed within the iron-rich matrix. The contrast between the bold, luminous colors and the dark, sturdy matrix makes Boulder opals particularly valuable and sought after. The opal in the image has been carefully polished to emphasize the brilliant color variety while preserving the stone’s natural contours.
Boulder opals like this are mined mainly in Queensland, Australia, and are popular with collectors and jewelry designers alike due to their unique play of color and their durability.
