Rhombohedral.
The crystal structure of dolomite is trigonal, meaning that it has threefold symmetry. It consists of layers of carbonate ions alternating with layers of magnesium and calcium ions. This results in a rhombohedral crystal shape.
Dolomite is a crystal of calcium magnesium carbonate, CaMg(CO3)2.
Marble is a metamorphic rock primarily composed of calcite or dolomite crystals. It typically exhibits a crystalline structure that can appear as interlocking, coarse-grained crystals, giving it a distinctive, often banded or veined appearance. The crystal shape can vary, but they generally form in a rhombohedral shape, contributing to the stone's aesthetic qualities when polished.
Dolomite typically displays a conchoidal fracture, which means it breaks along curved surfaces with sharp edges resembling broken glass. This fracture pattern is a result of the crystal structure and composition of dolomite, which is a type of carbonate mineral.
The crystal grain size of dolomite typically ranges from very fine to fine. Dolomite is a mineral composed of calcium magnesium carbonate and is commonly found in sedimentary rocks. The size of its crystals can vary depending on the specific geological conditions under which it forms.
Marble is a rock and rocks don't have crystal structures. However, marble does have a crystalline texture of visible interlocked calcite or dolomite mineral grains.
Pearls are not crystalline and don't have a crystal shape.
Agate, being a cryptocrystalline (microscopic crystal structure) form of quartz, does not have a crystal shape.
minerals get its crystal shape by the heating and pressure from rock
Dolomite is a metal, a dolomite mountain is a mountain made of dolomite
Crystal Symmetry is the ability of a crystal to shape by nature and has a symmetrical shape. It's also referred about the occupation of diamond cutters.
