Crystal – high-quality glass rhinestones with a brushed silver backing. Rhinestones with a shiny foil-like backing lack texture and are more likely to peel or fall off. Projects with crystal rhinestones are sturdier thanks to the unique bond they can achieve.*These stones can be purchased in individual colours. Jelly – resin rhinestones with an AB finish. They are named for their fun candy colours. These are a cost-effective alternative to crystal glass and a fun product to use in colourful projects.*They are sold ONLY in six or five colour collections.
