A diamond tennis necklace like the one pictured here is made up of dozens of individually small stones — which makes pricing it feel more complicated than a single-stone piece. It isn't, once you know what's actually being evaluated.
Total Carat Weight Is the Starting Point
A tennis necklace is made up of dozens of individually small stones, but what matters for pricing is the total carat weight across the whole piece, not any single stone. A necklace with smaller stones set densely can carry a similar total weight to one with fewer, larger stones.
Cut, Color, and Clarity Still Apply
Even in small melee-sized stones, cut quality, color grade, and clarity affect the price per carat. Bright, well-matched stones with good cut consistency across the whole necklace price higher than a mismatched or dull set, even at the same total carat weight.
The Metal Setting Is Priced Separately
Whether it's white gold, yellow gold, or platinum, the metal itself is weighed and valued on its own — a platinum setting, for example, adds real value on top of the diamonds since platinum is denser and pricier than gold at the same size.
How We Evaluate One
We look at the piece under magnification to assess overall stone quality, estimate total carat weight, weigh the metal, and put together one combined cash offer — all while you wait, no appointment needed.
