Diamond tester

If you've always wanted to know if those gemstone or diamond earrings grandma left you are real or not, purchasing a diamond tester is the best way to find out. No need to trek to a local jewellery store to have your earrings, necklace, or ring tested, as picking up a diamond tester is an easy and affordable alternative. You'll find a range of portable, battery-powered diamond testers to choose from on eBay, saving you time and money.

It's not a diamond, darling

Worrying that your partner has fooled you with a Cubic Zirconia ring instead of a diamond is now a thing of the past thanks to battery-powered diamond testers. With an LED indicator that flashes green if the diamond is real, it has never been easier to spot simulant stones such as Cubic Zirconia or Moissanite.

Some testers can evaluate other gemstones too such as amethyst and emerald. Test all your gems and gemstones and see just how much of your collection is genuine. With a new tester, there'll never be any doubt.

Alternatives to diamonds

Often, stones such as Cubic Zirconia and Moissanite are used to keep costs down and as an alternative to real diamonds in jewellery such as earrings, necklaces, and even that sparkler you're so proudly wearing on your finger. Many people want a conflict-free, sustainable alternative to diamonds, and Moissanite has soared in popularity in recent years as a diamond substitute. All well and good if you know that's what you're buying, but it pays to be cautious.

Easy to use

Diamond testers are simple to use and take minutes to give you an accurate result. Just pop the batteries in and test gems with the portable, pen-shaped device. Gemstone testers emit audible sounds and lights to let you know whether you're dealing with the real thing or not.
