Is the process for appraising jewellery different from that for appraising bullion or coins?

Bars or coins are usually made of pure gold or well-known alloys. However, when it comes to precious metal jewellery, there are many different compositions of a wide variety of materials, which can pose a challenge. With the CaratScreenPen, however, you can determine the fineness (karat) of gold non-destructively and in a matter of seconds. If you’d like to learn more about what to look for when testing jewellery, you can find detailed information on our gold testing page.
