Gold Tester

Gold Tester - the app that helps you identify jewelry alloys using a scale, calculates the density, and, accounting for measurement error, suggests possible options.

The app features a user-friendly interface:

Test jewelry, coins, and other items
Use scales of varying precision
Given certain conditions*, determine the fineness
Utilize differences in properties and color
Save and share your measurements

Focused on testing precious metals with various fineness:

Gold: 375/9K, 500/12K, 585/14K, 750/18K, 958/22K, 999/24K
Silver: 800, 830, 875, 925, 960, 999
Platinum: 850, 900, 950, 990
Palladium: 500, 850, 900, 950, 990

Supports contemporary non-precious jewelry metals:

Titanium
Tungsten
Tantalum
Stainless steel
Costume jewelry alloys
And others

* The app does not cover all possible metal options. It does not work with composite, hollow items, or items with inlays. The higher the precision of the scales, the more accurate the result. Data is correct at 20 °C and 1013.25 hPa.
