What people say
"GemPen is a literal game changer"
Since we adopted the GemPen into our business its completly changed how we verify our diamonds and gemstones which used to take us many hours and sometimes days to check and sort, now it takes minutes.
Zaq Caan - CEO www.harperkendall.com
"GemPen saved us a lot of time and money"
Having to sift and sort through many batches of diamonds regularly the GemPen makes the whole job a breeze.
Richard Cohen - Sales Manager Dynagem London
"GemPen quickly proved to be useful; The fact that you can screen multiple stones in a jewellery or in a batch of melee has been a real time-saver for us. It is the preferred tool for initial examination of jewellery to detect synthetics."
