Can you tell the karat or the gemstone from a photo?

No, and we never claim to. Karat, gemstone identity and weight cannot be read from an ordinary photograph. The studio labels such values as AI ESTIMATED and lets you enter what you know; the weight estimate is calculated from modelled volume and the alloy density you choose.

How accurate is the gold weight?

As accurate as the geometry. With a ring size or one measurement the range is typically within ±8–12%; hidden metal under stones and hollowed shanks widen the range, which we show explicitly.

Where does the daily price come from?

A public spot feed for XAU/USD refreshed daily, converted with daily FX rates into 25 currencies. Admins can override the spot price.

AI Jeweler

A gold weight calculator built on geometry, not guesses.

Upload a photo, calibrate the size, and the studio computes metal volume from the 3D model and multiplies by documented alloy densities. Below: today’s price per gram for every karat.

Full tables by karat and currency

Volume × density

Closed-mesh volume of the metal parts, stones excluded, times 10K/14K/18K/21K/22K densities for yellow, white and rose alloys.

Ranges, not false precision

Uncertainty from scale and hidden geometry is shown as a min–max weight and value.

Daily prices

Spot gold refreshed daily and converted into 25 currencies; admins can override the rate.

How it works

1
Upload photos
One or more angles of a ring, pendant, chain or bracelet; sketches and renders are fine.
2
AI models the construction
Band, setting, prongs, halo, stones and chain links are rebuilt as parametric geometry.
3
Calibrate
Give the ring size or one measurement; optionally the karat and stone details.
4
Edit by talking
“18K rose gold”, “2 carat centre stone”, “band 0.4 mm thicker”, “show it with emeralds”.
5
Weight, price, export
Volume-based gold weight for every karat, the day’s metal value in 25 currencies, STL for casting.

Typical alloy densities used (g/cm³): 10K yellow 11.6, 14K yellow 13.1, 18K yellow 15.6, 21K yellow 17.3, 22K yellow 17.8; white and rose alloys differ slightly. These are configurable, and every estimate states the assumption.

How the price is computed

Metal value = grams × (spot USD per troy ounce ÷ 31.1035 × purity), converted to your currency with the day’s FX rate. Stones, labour and retail margin are excluded unless a markup is configured.
