From 28 scans by 22 people in the GemstoneAI app, June 21, 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.
Aquamarine rings in white gold had a middle value of $1,400 across 15 scans, against $850 in yellow gold across 13.
| Gold color | Middle value | Middle half | Scans |
|---|---|---|---|
| Yellow gold | $850 | $520 to $1,600 | 13 |
| White gold | $1,400 | $950 to $2,600 | 15 |
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 | $590 | $350 to $680 | 6 |
| 2 carat or more | $2,300 | $1,300 to $2,650 | 16 |
Aquamarine value rises with the depth of its blue and with size, though large clean stones are not rare. Most aquamarine is heated to remove any green.
In gold, the metal sets a floor. 14K gold is worth about $76.28 a gram as metal today, so 5 grams of 14K holds about $381.39 of gold. Read the stamp, usually inside a band, on a clasp or on an earring post: 14K or 585, 18K or 750, 10K or 417. Without a readable stamp, GemstoneAI usually prices gold as 14K. GP, GF or HGE after the karat means plated or filled, which holds far less 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 28 GemstoneAI scans, the middle first-read value was $1,250, and half came in between $680 and $2,450. 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. Know the melt value of the gold first, since no fair offer should fall far below it.
In GemstoneAI scans, white gold ones had a middle value of $1,400 (15 scans) and yellow gold ones $850 (13 scans). At the same karat the two golds hold about the same amount of gold, so the gap reflects the stones and designs set in them, not the metal.
Gold aquamarine rings whose main stone the app estimated at 2 carats or more had a middle value of $2,300 across 16 GemstoneAI scans, with half between $1,300 and $2,650. Color, clarity and cut move a stone of the same size a long way.
