This pinkish orange very rare stone is a cousin to the more commonly found blue sapphire. The gemstone is currently only sourced in Sri-Lanka. Although many are located in Madagascar they are heavily treated to resemble the colour of the natural Sri-Lankan stone.
The name "Padparadascha" comes from Sinhalese meaning lotus blossom.
While the most perfect gem quality stone would be fully saturated medium pinkish orange, most laboratories will certify natural Padparadascha stones from lightish pinkish orange to medium orangish pink.
