These holes are formed in the Earth's crust bubbling gas in cavities circular or filling of the vein. When conditions permit, it forms hexagonal crystals are usually grown from a core. These crystals are most often not well developed, and so are generally found as groups of points are called Crystal and Amethyst Druze.

When heated mostly color may fade completely and to change a making a yellow Citrine. Because amethyst is more widespread, this is how the commercial Citrine is created. When Citrine and Amethyst are grown as naturally and at the same crystal creates alternating bands of yellow and purple creating what is called Amertine.
Amethyst: Synthetic
As I stated before, amethyst is so widespread and abundant on which make them very cheap and inexpensive. What makes it worse is that technology has advanced so far to make synthetic amethyst that mimics even and even the highest quality and amethyst is more difficult to distinguish between them. Manufacturers of synthetic amethyst have even learned how duplicate the natural process of growth as well, correct twinning axis, making more growth pattern identical to natural detection and make it more difficult. Laboratories can test every stone to detect synthetic amethyst, but this test is even more expensive than what is worth stone.
