Gemstone : Natural Chondrodite
Shape : Oval
Color : vivid yellow
Origin : Madagascar
Treatment: Not Heated. Not Treated. Not Enhanced.
Chondrodite is a nesosilicate mineral with formula (Mg,Fe)
5(SiO4)2(F,OH,O)2. Although it is a fairly rare mineral, it is the most frequently encountered member of the humite group of minerals. It is formed in hydrothermal deposits from locally metamorphosed dolomite. It is also found associated with skarn and serpentinite. It was discovered in 1817 at Pargas in Finland, and named from the Greek for "granule", which is a common habit for this mineral.
Mg5(SiO4)2F 2 is the end member formula as given by the International Mineralogical Association,[10] molar mass 351.6 g. There is usually some OH in the F sites, however, and Fe and Ti can substitute for Mg, so the formula for the naturally occurring mineral is better written (Mg,Fe,Ti)
5(SiO4)2(F,OH,O)2
