After Freshwater Cultured Pearls are drilled, the pearls are then matched as closely as possible. They are then strung into necklaces, pearl bracelets etc. First, they are sorted based on size differences. Freshwater pearls are usually sorted into sizes within 1 mm of each other. For example, there are 6-7mm pearls, and 7-8mm pearls, etc. These are easily sorted using common sieves. Afterwards they are re-sorted by color, luster, and body quality. This can be a long tedious and meticulous job.
The final pearl jewelry is then created by the stringers and labeled based on size and overall quality. The pearls are put on to 14 or 16 inch temporary strands called hanks. The technicians strive to create the best matched strand they can. After this the strands are labeled and shipped out to market. When received by retailers or wholesale traders, the jewelry is then finished by adding a clasp, earring post etc. They are then ready to be sold to the consumer.
