This is a rather special, candle quartz point (also known as an Atlantean Lovestar!).
It really does look almost like it's made of wax (it's not!) and has loads of tiny little crystal points growing from the base - hence the name.
Of the faces on its top point two are a matt milky white and the others are smoother more traditional quartz like.
It has a flat base and so stands upright and would look gorgeous on a mantle-piece or windowsill.
It stands about 13cm tall and is 8.5cm wide and 6.5cm deep.
It is mainly a whitish colour but it has many patches of yellowy and brown on it - the white looks like it has fallen from above and settled on the yellowish candle underneath almost like snow that has fallen.
