From 29 scans by 24 people in the GemstoneAI app, May 2, 2026 to November 7, 2026, with test and staff accounts left out and no one person making up more than a quarter of them. Each figure is a first-read fair market estimate from photos, about what a mainstream jeweler would sell a similar item for. They are not appraisals, sale prices or offers. How GemstoneAI values jewelry.
Sorted by the estimated size of the main stone. The size is the app's estimate from the photo, not a measurement.
| Main stone | Middle value | Middle half | Scans |
|---|---|---|---|
| Under 1/4 carat | $240 | $110 to $410 | 12 |
| 1/4 to 1/2 carat | $370 | $350 to $730 | 7 |
| 1/2 to 1 carat | $1,200 | $300 to $1,200 | 9 |
Diamond value turns on the 4Cs: carat, color, clarity and cut. A lab-grown diamond looks the same as a natural one and costs far less, and a photo cannot tell them apart, so a lab report settles it. Lab-grown vs natural diamond.
In silver, the metal adds little. Sterling silver is worth about $1.54 a gram as metal today, so 5 grams holds about $7.68 of silver, and the stone and the workmanship carry the rest. Sterling is stamped 925 or STER. Gold-colored jewelry stamped 925 is gold-plated silver, and vermeil is sterling with a layer of gold.
Most colorless stones set in sterling silver or plated metal are cubic zirconia or moissanite, because real diamonds are rarely set in silver. Have the stone checked with a diamond tester before you count on a diamond price.
A signed maker, age and good condition push a value toward the top of the range. Small or included stones, heavy wear and missing stones pull it toward the bottom.

Across 29 GemstoneAI scans, the middle first-read value was $360, and half came in between $220 and $900. Yours depends on the stone's size and quality, the metal and its weight, and the maker.
Less than these figures. They are fair market estimates, about what a mainstream jeweler would sell a similar item for, and dealers and pawn shops buy below that. Silver adds little as metal, so an offer rests mostly on the stone.
