Crystal formations are the different shapes and sizes that crystals can grow in. The formation of a crystal depends on a number of factors, including the type of mineral, the temperature and pressure conditions under which it formed, and the presence of impurities.
Crystals are the outer form of a mineral's inner order. Nearly every piece of rock of Earth is made of minerals, each of which is defined as a natural substance with a precise recipe and arrangement of atoms.
Crystal Point: A single terminated crystal which can have many of the other features below. Crystal points are the most basic crystal formation. They have a single point at one end and a wider base at the other end.
Double Terminated: Double-terminated crystals have two points, one at each end.
|Some Crystal Formations and shapes|
Twin: Two Crystal Points which are joined together by their side facets from the base up. Also known as a Companion.
Cluster: A group of many Crystal Points which grow from the same base.
Geode: A hollow rock which contains hundreds of crystals growing inside it.
Key: A hexagonal or angular shaped recess usually on the side facets of a crystal and near the base.
Rainbow: A rainbow reflection inside the crystal, caused by a special flaw. Only seen when it catches the light.
Inclusion: Other minerals caught inside a crystal. May appear as darker material or bits suspended inside the crystal.
Phantom: A ghost like 3D image of a crystal point inside a crystal. Shows the earlier size before it grew bigger. Some crystals have multiple Phantoms.
Isis Face: A five sided face with a tall point at the top. Also known as an Isis Crystal.
Generator: A Crystal Point with six equal sized triangular faces and a very central termination.
Window: A diamond shaped extra face on a Crystal Point. Also known as a Sixth Face.
Bridge: Bridge Crystals have at least one smaller crystal sticking out and penetrating the main body of the crystal.
Channelling: Channelling Crystals have a large seven sided face with two small triangular face on either side and one triangular face directly behind the main face.
Record Keeper: Record Keeper Crystals have one or more triangles visible on one or more faces of the crystal.
Elestial: Elestial Crystals are multiple points growing from the same main crystal body.
Aggregator: Aggregator Crystals are large crystals partially or totally covered in smaller crystals.
