Ruby in kyanite (also called ruby in apatite) is the trade name for a distinctive gemstone mined in Brazil. It is an alluring color combination of ruby along with a variety of blue (kyanite), green (apatite) and grey hues. This gemstone material is porous and has a low Mohs hardness, so it is stabilized using a colorless resin to improve its appearance and durability.
