JEWEL TOOL Diamond Sorting Sieves is the ultimate tool for professionals in the jewelry industry. Coming with an impressive inventory of 42 multi-sized disks (TJ01-02670-86), this set is specifically designed to simplify the diamond sorting process. The disks, which range in size from 0.90 mm to 4.40 mm, are carefully assorted to facilitate the easy and accurate sizing of diamonds. A handy sizing chart is lasered onto the top lid of the container, serving as a quick reference guide during the sorting process. The set nestles comfortably within a robust container featuring a diameter of 70 mm (approximately 2.75 inches), height being 2-5/8" (6.7 cm) and width 2-3/4" (7 cm). The sieve integrated into this ensemble possesses a diameter of about 66 mm or 2.6" (6.6 cm), ensuring a seamless sorting process. Crafted from stainless steel, the set showcases not only strength but also remarkable durability, a noteworthy feature considering the thinness of the plates. The non-sticky nature of the stainless steel plates ensures that stones do not adhere to the surface, facilitating easy use.

Designed for jewelers, gemologists, and hobbyists, this set promises accuracy and efficiency, ensuring that even the smallest diamonds can be sorted with ease and precision.
