Average hardness MOHS is the standard scale of hardness for minerals 1-10, with 10 being the MOHS of diamond. We also use the broad terms Hard and Soft for simplicity. Read more here. |

Origin | India |
A purple-brown migmatite with irregular pattern.
Small samples are rarely representative of entire slab due to variation.
Petrology:A mixed gneiss of different rock components. Light grey-violet to light brown-violet and orange feldspar and light grey-transparent quartz alternate throughout. Black and grey biotite is finely distributed. It can also occur concentrated in the form of stria, nests and clouds. The different colouring of the feldspar types is caused by their different content of iron oxide compounds.
Petrogenesis:Paradiso-Migmatite developed by partial re-melting of originally granite rock and slate sediment rock under high pressure and high temperature. This process took place at the border of the earth crust and earth mantle and lasted over geologically long periods. Here, mixing, partial solution, re-forming of minerals and crystallisation of gathered material occurred. The plasticity of the very ductile melt is visible by the folding structure and the direction orientation of the fine black-grey mica minerals. Such migmatite types are geologically very old.
