Professionals in Diamond Diagnostics typically spend their days inspecting and grading diamonds, producing detailed reports on authenticity, color, clarity, cut, and carat weight, and often verifying the origins of stones for ethical sourcing. Their work may also involve using advanced lab equipment, conducting quality control checks, and consulting with jewelers, buyers, or gem dealers. Collaboration with sales teams and periodic training to stay current with new diagnostic technologies are also common. The role generally balances independent analytical work with teamwork to ensure consistent standards and excellent client service.
