Intense Play of Color Queensland Boulder Opal – Australia – 9.91 ct – Unique Piece
Queensland Boulder Opal , from Australia , with a natural ferruginous matrix and veins of noble opal with intense green, yellow, azure, and blue reflections. The distribution of the opal within the rock creates a very dramatic contrast between the golden-brown matrix and the brilliant play of colors .
Australian Boulder Opals are among the most prized varieties for their natural structure, where the opal remains intimately bonded to the ironstone matrix. This specimen features an irregular yet well-balanced triangular shape, with a polished surface that enhances both the opal's veining and the natural pattern of the host rock.
A unique and very characteristic piece, ideal for collection , for studying the formation of Queensland Boulder Opals , or for a future handcrafted setting that keeps the strong contrast between the noble opal and the natural matrix visible.
