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.

Gemstone Cleavage Chart - Gemstone Information

21-10-2006  Cleavage is the tendency of a crystal to break cleanly along distinct planes. Since most gemstones are crystals, cleavage is an issue that gem buyers as well as jewelers and gem cutters need to take into account.

4.6: Identifying Minerals - Geosciences LibreTexts

Minerals often show characteristic patterns of breaking along specific cleavage planes or show characteristic fracture patterns. Cleavage planes are smooth, flat, parallel planes within the crystal. The cleavage planes may show as reflective surfaces on the crystal, as parallel cracks that penetrate into the crystal, or show on the edge or side of the crystal as a series of steps like rice terraces.

2.6: Mineral Properties - Geosciences LibreTexts

Cleavage is what we see when a mineral breaks along a specific plane or planes, while fracture is an irregular break. Some minerals tend to cleave along planes at various fixed orientations, some do not cleave at all (they only fracture). Minerals that have cleavage can also fracture along surfaces that are not parallel to their cleavage planes.

Cleavage vs Fracture - Difference

The main difference between cleavage and fracture is the characteristic manner in which a mineral breaks when subjected to any form of pressure or stress. A cleavage is the resulting smooth plane in a mineral as a crystal face breaks off to form a new crystalline face. A fracture, on the other hand, refers to that rough-edged, chipped shape of a mineral.

Garnet Garnet is a more complex orthosilicate (than olivine, for example) in which the SiO 4 tetrahedra are still independent. Garnets have the general chemical formula A 3 B 2 Si 3 O 12, where A is a divalent cation (Fe 2+, Ca 2+, Mg 2+, Mn 2+) and B is a trivalent cation (Fe 3+, Al 3+, Cr 3+).

Garnet: Mineral, January birthstone, abrasive, filter

What is Garnet? Garnet is the name used for a large group of rock-forming minerals.These minerals share a common crystal structure and a generalized chemical composition of X 3 Y 2 (SiO 4) 3.In that composition, "X" can be Ca, Mg, Fe 2+ or Mn 2+, and "Y" can be Al, Fe 3+, Mn 3+, V 3+ or Cr 3+.. These minerals are found throughout the world in metamorphic, igneous, and sedimentary rocks.

What is Gemstone Cleavage? - International

An uneven fracture produces a rough, uneven surface. Uneven fractures don’t have sharp points like splintery and hackly fractures. Gemstone Parting. The term parting refers to breakage of minerals along directions of structural weakness, such as twinning. However, unlike cleavage, parting isn’t present in all specimens of a given species.

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.
