Roll this Rose Quartz Oloid down a smooth inclined surface and you will witness the fun three-dimensional movement!

This large oloid is made from carved and polished rose quartz and makes for a unique piece of geometry.

As it rolls down a slightly inclined surface it gives you a glimpse of an amazing discovery: taking two congruent circles and placing them perpendicular to one another with the centres intersecting.

This geometry results in a perfect ball, with equal mass and surface area to a sphere. It's very satisfying to touch and roll around - just try it!

It's also a perfect gift for collectors of precious stones, geometry lovers or someone in need of a conversational design piece!

Display them on your desk or bookshelf for a reminder of the intricate designs in our world. 

Please note that gemstones and minerals are natural products and therefore vary in colour and detail. Each piece is unique.

Dimensions of Oloid: 4.2cm (l) x 4cm (w) x 3.5cm (h)
