This material cuts a nice bright stone and works in just about any design. I prefer to cut it in deeper designs because it is light enough and has great dispersion. This colour change garnet  is in limited supply and anything clean over 3 carats is large, so snap them up while you can as most of the ones I have listed below are over 6 carats!
