Gemometrics GemPen Filter 4


Gemometrics GemPen Filter 4.

The LW Filter 4 (in combination with Filter 1) helps the user to distinguish between a natural fluorescing diamond and a lab created one.

We highly recommend Filter 4 to be bought together with GemPenĀ® Diamond Screener.

Special Order Only. Allow 3-4 weeks for delivery.
