Fluorite specimen from the Cave-in-Rock District, Illinois, USA. Sharp, well-developed cubic crystals with stepped growth and distinct zoning, showing violet to purple coloration. Crystals are densely clustered on a limonite-rich matrix, representing a classic and highly collectible example from this renowned locality. 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.
