FAQs About Buying Loose Diamonds in New York

Are all loose diamonds at GEA Jewelers independently certified?

Yes. Our natural and lab-grown loose diamonds are accompanied by official grading reports from recognized authorities such as GIA (Gemological Institute of America) or IGI (International Gemological Institute).

Can I view loose diamonds in person before making a purchase?

Absolutely. You can schedule a private consultation at our New York workspace to view selected loose stones under professional gemological lighting before finalizing your setting.

What is the main difference between natural and lab-grown loose diamonds?
