The peninsula Kathiawar is famous for their rich occurrences at gem stones, in particular for the coloured jaspers and the mossy agates.

 The Indian coloured jasper is a very grateful gemstone, which can occur in many colours and is usually showing  a distinguished polishing ability. Gemstone-cutters like the green  mossy agagte from Kathiawar also.  Green tecto-silicates are responsible for the mossy-like structures.

Since the year 2002 so-called ”coral-jasper” is offered as a new variety in middle-europe.  It possesses an interesting agglomerated structure. However the fossil origin of this material is not yet proven.
