Tourmaline, is often referred to as the Rainbow Gemstone, and according to an old Egyptian legend, 'tourmaline on its long journey up from the centre of the Earth, passed over a rainbow'. The reality is that tourmalines are made of mixed crystals of aluminium boron silicate.

Rainbow Stone is a sand stone, just like blue stone or crab orchard and originates from India. Rainbow Stone is harder than crab orchard though, making it a more durable option. The name “Rainbow” comes from the natural patterns within giving it a “Woodgrain” look.
