Silica sand

A white Northland sand consisting of very fine crystalline silica (SiO2) grains, i.e. almost pure quartz. Creates a very bright and glary beach. Used for glass-making in Whangarei and Auckland.

The sand grains are best viewed under a magnifying glass or through a stereo microscope using good lighting.
