Foldable Jadeite Filter for Gem and Emerald Identification

The Foldable Jadeite Filter is specifically designed for gemologists to identify jadeite, emeralds, and other green and blue stones by transmitting only deep red and yellow-green light. It is most effective under strong electric light, and multiple stones can be examined simultaneously. This filter is especially useful for distinguishing emeralds from look-alikes and mixed-in jewelry, as well as checking gems like aquamarine and sapphires.

Featuring a high-quality glass filter, this tool enhances clarity and reduces distortion, providing better protection from humidity. The unique combination of two gelatin filters, which transmit deep red and yellow/green light, allows for accurate identification of natural emeralds, green beryl, and various green or blue stones. It is portable and does not require direct proximity to the stone, making it convenient for examining items even in display cases.
