This is a striking specimen of fluorite from the famous No. 4 Mine in Huanggang, Inner Mongolia, China. The piece is richly covered with deep indigo to midnight-blue fluorite crystals, showing a subtle frosted texture and some natural zoning. The crystals exhibit an attractive botryoidal to slightly cubic form, typical for this locality, and are scattered across a contrasting white matrix. The strong color and matte surface give the specimen an intense visual appeal under both direct and diffused lighting. This style of fluorite has become one of the most iconic mineral finds from Inner Mongolia in recent years and is now increasingly hard to obtain in quality specimens. 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.
