Beautiful specimen of Boulder Opal from Queensland, Australia. The opal displays attractive play-of-colour with flashes of blue, green, and purple, nestled in its natural ironstone host rock. A great addition for any opal or mineral collection. This specimen comes from a reputable source and has not been altered or treated in any way—what you see is its natural form. The photos are taken under daylight-equivalent LED lighting to show the specimen as accurately as possible. Please note: some colors can be difficult to capture accurately in photographs. I do my best to present the specimen faithfully. All items are professionally packed and shipped with tracking. I have many years of experience in international mineral sales and strive to provide accurate descriptions and high-quality service. Feel free to reach out with any questions—I'm happy to help.
