题目材料：
With scientific advances and the emergence of new diamond- producing regions (e.g., the Slave craton of Canada), research into natural diamonds has become invaluable for understanding the deep Earth. Although diamond merchants typically regard diamonds with visible inclusions [foreign bodies] as flawed, such diamonds are the most valuable for research, carrying samples of mantle minerals from depths as great as 800 km beneath the surface. Diamonds provide the perfect containers for these minerals, isolating them from the high pressure and temperature reactions within the Earth for geological time spans. Because even low elemental concentrations and minute features in diamonds can now be analyzed using instruments with higher sensitivity and resolution, studies combining the inclusions and their diamond hosts are powerful tools for geological research.
