The diamond if it is cut as a round brilliant gem, will measure 17.6MM at the girdle, which is almost three-quarters of an inch in diameter.

If it is a different cut, its measurement will be different.

Is a 20 ct diamond real?

Yes, a 20-carat (ct) diamond can absolutely be real. "Ct" refers to the carat weight of the diamond, and a 20-carat diamond is simply a very large and rare stone. However, because diamonds of that size are extremely valuable, it’s important to verify whether the diamond is: Natural or Lab-Grown: Both types can be real diamonds, but natural 20-ct diamonds are far rarer and much more expensive than lab-grown ones. Certified: A genuine 20-ct diamond should come with a certification from a trusted authority like IGI (International Gemological Institute) to confirm its authenticity, whether it is natural or lab-created. Key Points to Remember: Natural 20-ct diamonds can cost millions of dollars depending on their cut, color, clarity, and overall quality. Lab-grown 20-ct diamonds are more accessible in price but are still genuine diamonds chemically and physically. Looking for Certified, Ethical Diamonds?
