Garnet: The mineral Garnet information and pictures

Garnet is not a single mineral, but a group contains closely related, isomorphous minerals that form a series with each other. The Garnet members form intermediary minerals between each member, and may even intergrow within a single crystal. The Garnets vary only slightly in physical properties, and some of the members may be so similar that they are indistinguishable from one another without

Cleavage, Parting & Fracture (Physical Properties of Gemstone)

Cleavage, Parting & Fracture (Physical Properties of Gemstone) Cleavage is the tendency of a crystallised mineral to break in certain definite directions, giving more or less smooth surfaces.

What is Gemstone Cleavage? International Gem Society

A break in a gemstone that doesn’t occur along cleavage planes is either a fracture or a parting. [toc] Gemstone Cleavage. Since the atomic arrangement within a crystal is symmetrical, the planes of specific bonds are symmetrically disposed within the crystal. Internal cleavage planes are, therefore, as symmetrical as external crystal faces.

Gemstone Cleavage at AJS Gems

The difference between a cleavage and a fracture is that a fracture is arbitrary and non-repeatable -- it can occur anywhere on the body of a mineral, in any spatial direction, with little chance of an identical fracture occurring. A cleavage, on the hand, is predictable and repeatable. A mineral can have one or more cleavage planes.

Identifying Minerals Geology

Fracture is a break in a mineral that is not along a cleavage plane. Fracture is not always the same in the same mineral because fracture is not determined by the structure of the mineral. Minerals may have characteristic fractures (Figure 9). Metals usually fracture into jagged edges. If a mineral splinters like wood, it may be fibrous.
