From 33 scans by 26 people in the GemstoneAI app, May 21, 2026 to November 6, 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 |
|---|---|---|---|
| 1/2 to 1 carat | $180 | $140 to $310 | 6 |
| 2 carat or more | $330 | $170 to $650 | 19 |
Ruby is priced on the strength of its red, then size and clarity. Lab-created ruby has been made for over a century and turns up often in vintage jewelry, and glass-filled ruby sells for a fraction of untreated stone.
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.
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 33 GemstoneAI scans, the middle first-read value was $250, and half came in between $130 and $650. 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.
Silver ruby rings whose main stone the app estimated at 2 carats or more had a middle value of $330 across 19 GemstoneAI scans, with half between $170 and $650. Color, clarity and cut move a stone of the same size a long way.
