The crystalline mineral amethyst is a variety of quartz and may be found in situ (in place in the rock it was formed in) in small cavities called Vughs mainly in rocks of volcanic origin. This is not very helpful if you want to find them easily. perhaps the best place to find them easily is on the seashore, where amethyst pebbles can often be found where streams have intersected volcanic rocks on their way to the sea and washed down the amethysts onto the gravelly beach deposits.
