Pineapple Quartz is the name given to a silicon dioxide mineral and is characterized by hundreds of small terminations forming around the base and sides of the main crystal termination all of which point in the same direction. Most of this form of Quartz is from Madagascar and the colour is off white/cream, sometimes with pinkish/red/brown markings and inclusions.

Quartz is one of the most well-known minerals on earth. It occurs in basically all mineral environments, and is the important constituent of many rocks. Quartz is also the most varied of all minerals, occurring in all different forms, habits, and colors. There are more variety names given to Quartz than any other mineral.

Quartz belongs to the trigonal crystal system. The ideal crystal shape is a six-sided prism terminating with six-sided pyramids at each end. In nature quartz crystals are often twinned (with twin right-handed and left-handed quartz crystals), distorted, or so intergrown with adjacent crystals of quartz or other minerals as to only show part of this shape, or to lack obvious crystal faces altogether and appear massive.
