Is a GIA diamond worth it?
1 Answer
1stDibs ExpertSeptember 16, 2024

Are GIA diamonds worth more?
1 Answer
1stDibs ExpertAugust 20, 2024
Yes, in many cases, GIA diamonds are worth more. To gain Gemological Institute of America (GIA) certification, a diamond must meet very high standards. As a result, diamonds that carry the certification usually have high color, cut and clarity ratings, making them more valuable than gemstones that can't meet the standards established by the GIA. Also, people may be more willing to pay high prices for GIA-certified diamonds because the certification is a testament to their quality. Shop a large selection of diamond jewelry on 1stDibs.
What does GIA mean in jewelry?

During the 1950s, GIA unveiled a grading system to help consumers evaluate diamonds, and you will still see GIA ratings used today to describe the cut, clarity and color of gemstones.
