HAJ: Jewelry Identifier

HAJ: Jewelry Identifier is a practical gold-testing and jewelry record app designed to help jewellers calculate density and review estimated purity using hydrostatic weight measurements.

Create a new test by entering the customer name, jewelry weight in air, suspended weight in water, and any required touch adjustment. Select the relevant alloy assumption—Copper, Mixing, or Silver—and the app automatically calculates the density and displays the estimated purity-related result.

The app also helps you calculate testing charges, labour fees, and the net payable amount. Completed tests can be saved as receipts and accessed later through the customer history.
