The crucial third clue for finding new diamond deposits is the presence of indicator minerals. These minerals, such as garnets, chromites, and eclogitic garnets, are often found in association with diamonds. When geologists discover these indicator minerals in soil or rock samples, it suggests the potential presence of diamonds in the area. Additionally, the minerals’ chemical composition and physical characteristics can provide valuable information about the depth and nature of the diamond source. Combining these indicators with geological knowledge and exploration techniques, geologists can significantly improve their chances of locating new diamond deposits, making indicator minerals a critical tool in the search for these precious gems
