Refractive Index (RI) is the slowing that is characteristic of since it travels through a given treasure species or substance. The higher the RI, the greater luster and brilliance can be done. The undeniable fact that each gem features its own RI causes it to be necessary to facet each species at slightly various angles and makes it a characteristic that is useful gem identification.

We studied the dissolution of biotite and chlorite in laboratory systems with flow-through and batch reactors. The initial dissolution of biotite in the near-neutral pH region, under N 2(g) atmosphere is highly non-stoichiometric. A slow linear release of iron during a period of weeks indicates a surface-chemical-reaction-controlled mechanism of release for iron.
