Why two 1-carat stones can differ by hundreds of dollars
Two 1-carat stones with similar headline weight can still land hundreds of dollars apart. Color, clarity, and cut grades each move the price, and the same combination of grades can be listed at different prices by different retailers. Retailer markup differences add another layer on top of the spec spread. That is why a single median never tells the whole story — the shape table above shows part of the spread, and the rest comes down to the exact grades and where the stone is listed.
How to check a specific stone's price before buying
Take the stone's carat weight, shape, color, clarity, and cut, then search for that combination in Search to see matching listings side by side.
