Lab-grown status must be explicit
BUYER QUESTION · Trust and Reports
Are lab-grown diamonds real diamonds, and how do they differ from natural diamonds?
Lab-grown diamonds are diamonds, not moissanite or cubic zirconia. The central difference is growth origin. The practical buyer check is clear lab-grown disclosure, a verifiable report, and a match between the listed product and its documentation.
DECISION PATH
How to decide
Verify the number with the issuing laboratory

EVIDENCE BOUNDARY
What these examples prove
Product examples show origin disclosure. Any report claim must be verified against the actual document for that item.
Product cards show public snapshot fields, not independent verification of the physical item, a single center stone, a report or delivery.
Only anonymous public catalog data is used. Internal purchase prices, customer data and private inventory fields are not shown.

FAQ
Common follow-up questions
Can the eye identify a lab-grown diamond?
Origin generally cannot be determined reliably by sight alone; professional testing and a verifiable report are needed.
Can a basic diamond tester identify origin?
A simple tester cannot reliably determine growth origin and does not replace laboratory analysis.
Will a lab-grown diamond change color with wear?
Normal wear does not turn diamond into another material. Surface film, the setting or plating can change its appearance. Clean and inspect the ring instead of using appearance to infer origin.
Is CVD or HPHT lab-grown diamond better?
They are different growth methods, not quality grades. Ask for growth and post-growth treatment disclosure, then compare the individual stone's verifiable cut, color, clarity, measurements and report.
