Pearl sieves are used to simplify the sorting of stones and beads by size. This sieve set includes 15 plates measuring 66mm in diameter, designed for sorting Pearl, gemstones, gems, stones, diamonds, and crystals ranging from approximately 1.10mm to 4.50mm in size. It comes in a zippered leather case for easy storage and transport. Additionally, a convenient diamond size/weight and sieve plate number chart is engraved on the inside of the cover for quick reference.

Jewelers use sieve sets to sort gems by size. Each set has sieves with different-sized holes and a chrome sorting container. You can choose from two container sizes, both with the same number and range of plates. The container also serves as storage for the sieves when not in use.

Handmade sieves are great for sorting rough and polished Pearl, lasting a long time. They come in four diameters, sealed in a durable container. Specifically for sorting diamonds, they have 15 plates from 00 to 20.
