diamondcontaining

Diamond-containing is an adjective used to describe any material, rock, or article that includes diamonds in its composition. The term covers natural occurrences as well as synthetic or engineered materials where diamond is present, often as crystals, grains, or a continuous phase.

In geology, diamond-containing rocks are most famously associated with kimberlite and related mantle-derived rocks that carry diamonds to the surface during volcanism. Diamonds occur as mineral inclusions within host minerals or as discrete crystals, and they can be recovered by mining and evaluation of the rock's age, formation conditions, and diamond grade.

In industry and materials science, diamond-containing materials include natural or synthetic diamonds embedded in composites, or diamond layers and coatings. Synthetic diamonds are produced by high-pressure high-temperature (HPHT) or chemical vapor deposition (CVD) methods and are used in cutting, grinding, drilling, and polishing tools, often in polycrystalline forms such as PCD or PDC.

The term is used across disciplines and emphasizes presence of diamond; properties depend on particle size, crystallinity, orientation, and whether diamonds are part of a matrix. See also: diamond, kimberlite, polycrystalline diamond.
