Diamond origin
Natural and lab-grown: two distinct sourcing decisions
Natural and laboratory-grown diamonds have different origins. Professional sourcing should preserve that distinction from the first search through final disclosure.
Keep origin explicit
Natural diamonds form through geological processes. Lab-grown diamonds are produced using controlled technological processes. Do not treat a grading description as a substitute for a clear origin disclosure.
Assess the intended use
Consider the customer brief, budget, size requirements and merchandising position independently for each category. Compare offers within the same origin category.
Verify documentation
Read the grading report and verify it with the issuing laboratory when a verification service is available. Confirm the report identifies the diamond origin and matches the offered stone.
