Make sure you have the proper light in or away from your office. This light source simulates daylight for diamond grading and has longwave UV light for fluorescence. The grooved, built-in grading tray is made of near-perfect white hard plastic that can be easily cleaned and will not change color.
Powered by batteries, the unit is small enough to fit in your briefcase.
In the package: leatherette box, lamp with daylight tube and a UV tube, sorting tray.
