Here we have a very eye catching, man-made Chalcanthite. Awesome group of sharp and lustrous crystals with intensive blue colour set on slag matrix. Name comes from the greek "chalkos" and "anthos" meaning copper flower. Beautiful decorative piece with uncommon shape. Don't put it into the water. 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.
