If the item in question matches these characteristics, it is likely hematite, but it would be best to have it examined by a professional to confirm. **

However, the water can also cause the iron oxide in hematite to oxidize further, potentially changing the color of the mineral. Additionally, the natural luster of hematite may be lost as the water washes away any surface coatings or patinas that contribute to its metallic sheen. **
