To ensure the quality of his product, The Peter Stone Company purchases raw silver and produces the true .925 alloy in his own factory. Peter also personally buys the different gems necessary for their various designs. All rings are cast to size and craftsmen cut and inlay each stone for a perfect fit. Every piece of jewellery created is hand polished, not tumble polished. The difference is noticeably visible and shows the care and pride taken in each individual piece.
