Magnificent specimen of Orange Calcite from the Grabiszyce quarry. The Grabiszyce quarry is renowned for producing some of the finest examples of Calcite in the world, and this Orange Calcite specimen is no exception. Fluorescent in long waves. 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.
