Gemstone and Diamond Testers at Cooksongold

Here at Cooksongold, we have everything you need to create professional looking jewellery. We know how important quality is, which is why we have a range of moissanite and diamond tester pens- so you can ensure that whatever you are creating, you do so with only the highest quality gemstone.

All of our gemstone testers and diamond testers are battery operated, and are cleverly designed with a large illumination panel to ensure a clear view. The easy to use touch grip will also always ensure accurate results. These gemstone testers are a quick and easy way to ensure the gems you are working with or buying, are not imitations.

All of our diamond and moissanite testers are industry approved and easy to use for both gemstone experts and beginners. For more information on any of our gemstone testers or diamond testing equipment, speak to one of our expert team members today on 0345 100 1122.
