Question 1

How can I tell if a diamond is real at home?

Accepted Answer

You can check for reflections, fog test, and scratch test — but none of these methods are fully reliable. For 100% certainty, use a gemological certificate from IGI or GIA.

Question 2

What’s the most accurate way to know if a diamond is real?

Accepted Answer

The most reliable method is checking a gemological certificate issued by a trusted lab like GIA or IGI. The certificate confirms if it’s natural, lab-grown, moissanite, or synthetic.

Question 3

Are cheap diamonds real?

Accepted Answer

Sometimes yes — for example, lab-grown diamonds can cost much less than natural ones. But be cautious: if the price seems too good to be true, check the certificate to avoid scams.
