Metal Density Reference for Jewelry and Casting
Density links volume to weight. With it you can estimate how heavy a design will be before it is made.

Typical values only: alloy recipes differ between suppliers and between white, yellow and rose colours.
Formulas
- Weight (g) = volume (cm³) × density
- Volume (cm³) = weight ÷ density
- 1 cm³ = 1,000 mm³

Frequently asked questions
Can I find purity from density?
Only roughly, and not reliably for alloys with unknown composition. Use assay testing.
