Gold Density Screening Tool
Enter a gold item's measured mass and physical dimensions to estimate its density and compare it with the expected density of high-purity gold (19.32 g/cm³). This is a useful initial physical check.
Density alone cannot authenticate gold. Some counterfeit materials (notably tungsten, density ≈ 19.25 g/cm³) can have a density very close to gold. For material transactions, use professional testing.

Some counterfeit materials (notably tungsten, density ≈ 19.25 g/cm³) can have a density very close to gold. A density screen is a useful initial check, not proof of authenticity. For material transactions, use professional testing (XRF, ultrasound, or assay).
This tool performs an arithmetic density estimate only. It does not verify authenticity. Learn how to verify physical gold.
How density screening works
The tool calculates volume from the item's dimensions (length × width × thickness for a bar, or π × radius² × thickness for a coin) and divides the measured mass by that volume to estimate density.
If the calculated density is broadly consistent with the expected range for high-purity gold, the item passes this initial screen. If it differs materially, further verification is warranted.
