Dogtooth calcite also known as Dog-Tooth Spar is a cave formation made up of large and often sharp crystals which bear a slight resemblance apparently, to dogs teeth hence its name. Calcite is one of the most abundant and varied minerals on the planet and there are more than 300 different types of calcite crystals of which Dogtooth is one.
In mineralogy spar is a generic term for any transparent to translucent, usually light-colored and vitreous crystalline mineral.
The crystals in dogtooth calcite grow very slowly over long periods of time in large open cavities and often underground in limestone caves. It takes billions of 'unit cells' to form just one visible crystal.
This dogtooth calcite was a new find for us and something we'd never heard of or seen before so as soon as we saw it, we knew we had to have it for our collection.
