      Hello ! I reduced a raw sapphire of 3g ( 15 , 16 carat ) that baught in sri lanka , sapphire collection , it’s slightly bluish on the inside and milky , I obtained a 6 carat cylinder ready for an SRB shape with a beautiful polish , It seems to me ! My difficuly is to know it’s cut for the crown and it’s pavillon , because it is wider than it is long , not easy to unsderstand the angles for the best result .
      Best wishes !
