Acrylic glass, scientifically known as polymethylmethacrylate or PMMA, is commonly referred to as plexiglass. Because of its elasticity, this synthetic material is often used as an alternative to the ordinary glass. Acrylic glass is appreciated in jewelry making since this material - in contrast to ordinary glass - is light, less delicate and also more transparent. Acrylic glass let UV- light pass through which leads to shiny and twinkling effects in disco lights. Other advantages of acrylic glass are: It is non-toxic and resistant to ageing and to weathering.

PVC (Polyvinyl chloride) is a soft and elastic material (commonly referred to as ´plastic´). PVC´s main features are very high resistance, minimum weight and thermal conductivity. PVC is skin-friendly and allergies to it are rarely found. injuries resulting from wearing PVC jewels are very unlikely due to its softness and elasticity.
