Example
Jewelry Metal Weight Estimator
Sample: 2.4 cm³ volume in 14k gold
Example shown — replace it with your own piece's volume and metal.
Volume
2.4 cm³
Metal
14k yellow gold
Result
How it works
- Enter your piece's volume in cubic centimeters.
- Choose the metal and karat or purity.
- Get an estimated finished weight in grams.
The method
Weight equals volume multiplied by density. Common metal densities are built in, so you only need to supply the piece's volume and metal choice.
FAQ
How is jewelry weight estimated from volume?
Weight is volume multiplied by the metal's density — for example 14k gold is about 14.0 g/cm³, so a 2.4 cm³ piece weighs roughly 33.6 g.
Does this account for stones or hollow sections?
No — the estimate assumes solid metal. Subtract stone volume or hollow cavities from your total volume first for a more accurate figure.
Is this precise enough for casting quotes?
It's a solid starting estimate, but always confirm final weight with your caster once a wax or CAD model is finalized.
