Complete filter kit
The Filter Kit contains all the additional Filters. This is the Add-on to GemPen Diamond Screener which effectively upgrades it to GemPen Premium.
The filter Kit contains filter 2, 3 and the LW Filter 4. These filters in combination with the standard filter 1 makes it the most versatile option and offer the user the means to truly study Diamonds and gemstones and search for discrepancies in the fluorescence and phosphorescence for further analysis.
