Across 16 plated cubic zirconia rings scanned with GemstoneAI, the middle value was $35. Half came in between $25 and $40.
From 16 scans by 15 people in the GemstoneAI app, May 31, 2026 to November 8, 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.
Cubic zirconia is a lab-made diamond look-alike worth very little as a stone, so the value sits in the metal and the workmanship. The stamp tells you whether that metal is solid.
Plated jewelry, which here includes gold-plated, rhodium-plated, vermeil and stainless steel, has little or no metal value, and GemstoneAI gives it none. GP, GEP, HGE or RGP after a karat means a thin layer of gold over another metal. What plated stamps mean.
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 16 GemstoneAI scans, the middle first-read value was $35, and half came in between $25 and $40. 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. Plated metal has almost no value, so an offer rests on the stone.
