SS sizes like SS20 or SS40
The SS sizing system dates back a long time. The SS stands for stone size.
To determine their size, the stones are passed through a series of sieves of diminishing hole diameters, thus classifying them into a size range.
We prefer the metric system at ALLSTARCO, but continue to also carry the SS equivalent where applicable.
The leading manufacturer of lead crystal rhinestones, Swarovski, publishes a table of SS to mm size conversions.
