Collecting tips
- Look in Alluvial Deposits. Bloodstone is often found as water-worn pebbles and cobbles in riverbeds and stream gravels, especially in areas downstream from volcanic or hydrothermally altered rock formations.
- Identify Associated Rocks. Search in areas with volcanic rocks (e.g., basalts, andesites) or in regions known for hydrothermal alteration, as these environments are conducive to chalcedony formation.
- Examine Color and Inclusions. Look for the characteristic dark green color with distinct red (hematite) spots. The red inclusions are key to distinguishing bloodstone from other green chalcedony varieties.
- Check Hardness. Bloodstone has a Mohs hardness of 6.5-7, meaning it can scratch glass and steel. This helps differentiate it from softer minerals.
