These fantastic yellow cats eye hearts are man-made from glass fibre which is a material made from ultra-fine fibres of glass. As the stone interacts with light it becomes exceptionally chatoyant which is an optical phenomenon seen in some natural minerals most notably chrysoberyl cats eye and tigers eye.
Natural chrysoberyl cat's eye when polished displays a band of concentrated light across one section of the stone caused by inclusions of fine parallel fibres that reflect light in a single band. Those fibres in the case of this synthetic crystal are glass.
These rich yellow coloured cat's eye hearts make great gifts particularly for younger rock and mineral enthusiasts and the exceptional chatoyance caused by the reflection of light is really quite fascinating.
Each polished cats eye heart comes in a colourful gift pouch and orders placed before 2pm will be dispatched on the same day.
