How We Evaluate Diamond Value (The 4Cs)
We evaluate every diamond using the four industry-standard quality factors: cut, color, clarity, and carat weight.
Cut refers to how well the diamond’s facets interact with light. A well-cut diamond reflects light efficiently and is a significant factor in its market value.
Color is graded on a scale from colorless to light yellow or brown. Colorless diamonds are generally more valuable, though some fancy colored diamonds command premiums of their own.
Clarity describes the presence or absence of internal inclusions and external blemishes. Diamonds with fewer inclusions visible under magnification receive higher clarity grades.
Carat weight measures the diamond’s physical size. Larger diamonds are rarer and, all else equal, more valuable per carat.
These four factors are assessed together with current market conditions to determine the offer we make. You receive a clear, itemized explanation before deciding whether to accept.
Our guide to the 5 Cs of a diamond explains how each grading factor is measured and what the grades mean for an offer.
What Diamond Items We Buy
We purchase a wide range of diamond items, including loose diamonds of all shapes and sizes, diamond engagement rings and wedding bands, diamond earrings, pendants, and bracelets, estate diamond jewelry, and multi-stone diamond pieces. For engagement-related inventory, see our engagement rings page.
We evaluate diamond jewelry in a range of conditions. Items with chips, missing prongs, or damaged settings are still assessed — offer amounts reflect the condition and the stone quality.
Certified vs. Non-Certified Diamonds
A diamond certificate — such as a GIA, AGS, or EGL report — documents the stone’s 4Cs grading by an independent laboratory. Certified diamonds can be verified against the report during evaluation, which speeds the appraisal process and strengthens offer confidence.
A certificate is not required to sell. We evaluate uncertified diamonds in person using our own testing and grading tools. If you have any documentation, receipts, or original packaging, bring them along — they are helpful but not mandatory.
