Stone Size Guide These stone size strips proved so popular at events and shows, we've decided to add them to general sale! A laminated guide to your rhinestones sizes - an excellent reference point to keep in the pen pot on your craft desk! It's all very well being able to find stone sizes online (e.g. our own website reference), but this is a to-scale tool so you can even sit a stone on it if you're not sure what size it was and need to re-order. Much easier to get your head round than trying to figure out "point-something-of-a-millimetre"!
