Getting started

Choose a calculator from the home screen, select the material or stone shape, and enter the required measurements. Results update when the inputs change. No account or registration is required.

Calculators and results

Check the selected units, metal fineness, solder recipe, stone dimensions and quantity. Diamond carat weights are estimates; use scales to determine actual weight. Reference results do not replace professional assessment.

Metal quotations

Quotations require an internet connection. Check the displayed update time and use Refresh quotes to retrieve the available server quotation. If an update fails, the app keeps the last successfully received quotation and its date. These are reference market prices, not a retail purchase or sale offer.

Languages and saved information

Choose your preferred interface language on the Language screen. The app remembers this preference and caches market quotations on your device. It does not maintain calculation history.
