Across 13 silver blue topaz rings scanned with GemstoneAI, the middle value was $120. Half came in between $85 and $180.
From 13 scans by 13 people in the GemstoneAI app, May 9, 2026 to November 5, 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.
Almost all blue topaz is colorless topaz treated to turn it blue, which keeps it plentiful and affordable. Deep London Blue sells for a little more than pale Sky Blue.
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.
Photograph it, then take a close-up of the stamp. GemstoneAI identifies the stone, reads the metal and gives a first-read value with similar items for sale. Your first scan is free.

Across 13 GemstoneAI scans, the middle first-read value was $120, and half came in between $85 and $180. 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.
