Colour and design
Its heart-shaped outline with a central cleft gives the stone a distinctive starting point for a personal jewellery design.
The purple colour offers an expressive alternative for a coloured-stone ring, pendant or coordinated jewellery design. A heart shape makes the outline part of the design itself. Compare the width and length, and discuss a setting that keeps the cleft and pointed tip visible.
