Understanding SS size and PP size references--easily convert stone sizes to millimeter and inch size ranges for designing.

Rhinestones are measured in a ''range'' of sizes rather than a precise measurement, using the following:

PP (Pearl Plate) is a method of sizing originally used for pearls by placing them on a surface or plate with holes. The pearls were sized by which holes they fell through. PP is usually used for smaller stones. Pearl plate has a variance of 1/10 of a millimeter.

SS (Stone Size) is the most current method of rhinestone sizing, although PP is still used. Some stones will have both a PP and SS size on the package label.

Please note: Smaller point back rhinestones are measured in PP (Pearl Plate) and flat back and larger point back rhinestones are measured in SS (Stone Size).
