Laboratory-grown diamonds, described clearly.
JoKiwi identifies laboratory-grown diamonds as laboratory-grown and keeps growth method, grading information, and report availability tied to the selected variant.
Last updated 20 September 2026
What laboratory-grown means
A laboratory-grown diamond is produced in a controlled environment rather than mined. CVD and HPHT are the two commonly stated growth methods. A product may also receive post-growth treatment, which should be disclosed when verified.
How JoKiwi labels products
- The words laboratory-grown or lab-grown appear with the diamond description.
- CVD or HPHT appears only when the source record or report supports that method.
- Carat weight, color, clarity, cut, treatment, and report claims remain variant-specific.
- Unknown or unverified grading details are not converted into a quality claim.
Grading reports
Some stones may be offered with an independent laboratory report. Availability and price can vary by stone size and variant. Before ordering, confirm the laboratory name, report number, inscription or matching method, grading results, and whether the report is included in the quotation.
A grading report records an independent laboratory assessment. It is not a monetary appraisal and does not guarantee future value.
Color and appearance
Photography, screen settings, stone cut, lighting, and surrounding metal can change how a stone appears. Product images help selection but do not replace the written specification or an available grading report.
