FAQ about Natural Diamonds

There are a few different ways to determine if diamonds are real - some of them require lab equipment that you’ll only find in a gemologist’s office. First and foremost, look at the quality and overall appearance. Does the stone look shiny and very sparkly or dull and lifeless? They have an adamantine finish which is hard to replicate in any other simulant material. Next, check for the laser inscription on the girdle. Every diamond sold from Rare Carat will have one. You need magnification to find it, but once you do, match up the inscription with the grading report and lab. Finally, take it to a local graduate gemologist/appraiser. This is a sure thing. They will be able to tell you all the details about your stone and if it’s a real or not.
