Step 1
Ask if the stone is a genuine diamond or if it is a cubic zirconia, moissanite or other synthetic substance. A reputable jeweler will give you an honest answer.
Step 2
Look at the setting and mount. Since stones such as cubic zirconia are so much cheaper than diamonds, they are sometimes set in inferior metals.
Step 3
Check the wear and tear on the stone. A cubic zirconia is not as durable as a diamond and may show signs of scratches or nicks.
Step 4
Take the stone to a trusted jeweler. Looking through a jeweler's loupe, he or she should be able to spot a fake stone right away. If the jeweler cannot tell by examining the stone, he or she will have instruments that can verify its authenticity.
Step 5

It is highly recommended that you obtain a certificate from the Gemological Institute of America (GIA). The GIA, the largest impartial diamond grading authority in the world, issues a grading report after it examines the diamond and details it specifications.
Step 6
Have the stone appraised by an independent appraiser who is affiliated with a professional organization such as the American Society of Appraisers (ASA). Ask for a certificate indicating the value and characteristics of the stone.
