Oxygen solutions

The all three diamond crossections have almost same measurements. Possible shapes are round or princess. The bigger stone can be SI2 grade with higher mass or it can be smaller with VVS2 clarity grade. The most valuable solution is two princess cuts: the bigger diamond is clean and the smaller one is included.
