These pages contain all our amethysts that contain or have formed in what is known as a "phantom" formation. It is true to say that usually any phantoming within amethyst are also likely to be of the quartz family - generally clear or smoky quartz, or sometimes citrine.
Phantom formations are used to describe crystals that show lines, layering or "ghosts" within them. These might be of a completely different mineral than that of its host if a new mineral has been temporarily introduced into the seed / feed solution during the crystal's growth; or it may be as a consequence of changes or mutations to the minerals within the usual feed solution; or it may be that changes have occurred to conditions that affect the crystal's growth within the earth surrounding the mineral, such as increased /decreased heat or pressure.
The fact that layers are formed is symbolic and points to the crystal being of use when dealing with buried or layered issues, or when accessing information that occupies a different level of reality, time or dimension. Just as the phantom shows the crystal's history, so too can it show our past to us.
