Diamond identifier · Experimental
Screen a diamond-like stone.
Colourless stones are among the hardest to separate by eye. We look at visible facet behaviour and wear, list plausible look-alikes and explain what testing would actually settle the question.

Questions
Is a laboratory-grown diamond fake?
No. A laboratory-grown diamond is diamond. Separating it from a natural diamond typically needs specialised laboratory instruments.
Can you give me the 4Cs?
No. Formal grading requires controlled conditions, calibrated equipment and the loose stone in most cases.
Does a fog or breath test work?
Home tests like these are unreliable and can mislead. We don't use them as evidence.
Should I scratch, heat or apply acid to test it?
No. Destructive home tests can damage the item and still mislead. Record what you can see and seek qualified testing when the answer matters.
