Director's Notes

Burma is the source of the world's finest rubies. Known for their pink-red through to a deeper blood red colour, the stones have a pure and highly saturated colour. The presence of the trace element chromium in their chemical makeup, allows these rubies to fluoresce in natural daylight, giving them the added allure of glowing from within.
