GemPen® | Red Dot Design Award

With this screening tool, it is possible to reliably determine whether diamonds, rubies and sapphires are of natural origin or synthetically produced gems, and whether they were subjected to value-enhancing measures. The device operates with four different filters to determine the value of the test specimen at hand. The battery-powered GemPen is resilient and comes with a travel case which, like the tool itself, guarantees safe and correct usage due to its shapes, surfaces and graphics.
