How are industrial-grade diamonds used differently from gem-quality stones?

• A. Industrial-grade diamonds are used for cutting and grinding, while gem-quality stones are cut for jewelry.
• B. Industrial-grade diamonds are primarily used in jewelry; gem-quality stones are used for industrial tools.
• C. Industrial-grade diamonds and gem-quality stones are used interchangeably with no differentiation.
• D. Industrial-grade diamonds are synthetic.

Answer: (A)

Industrial-grade diamonds are valued for their hardness and abrasion resistance, so they’re used as cutting tools, grinding wheels, drill bits, and in diamond powders to shape and finish hard materials. Gem-quality stones are cut and faceted to maximize optical beauty—color, clarity, and brilliance—for jewelry. The core distinction is function: industrial diamonds maximize performance in material removal, while gem-quality stones maximize aesthetic appeal for adornment. Hence the statement that industrial-grade diamonds are used for cutting and grinding, while gem-quality stones are cut for jewelry is the best description.
