How diamond value is evaluated

We explain what drives value so you understand your offer.

Cut

Cut quality strongly affects brilliance and demand.

Color & clarity

Grades influence value along with visible appearance.

Carat

Larger stones may command different pricing dynamics depending on demand.

Documentation

Certificates can help provide context, but aren’t required.

What to bring

  • Any grading reports/certificates (optional)
  • Original mounting/setting if available (optional)
  • Government-issued ID (required)

FAQ

Answers to common questions.

Do you buy loose diamonds without a certificate?

Yes. We evaluate loose diamonds with or without documentation.

What affects a diamond’s value the most?

Cut, color, clarity, carat, fluorescence, condition, and current market demand.

Can I sell diamond jewelry too?

Yes. We evaluate diamond rings, earrings, bracelets, and other jewelry in person.

Do you buy natural diamonds only?

Yes. We specialize in natural diamonds.

Should I bring a GIA report?

If you have it, bring it. Reports help confirm characteristics, but we can still evaluate without one.
