Comments:
Umba sapphires are a great kind of sapphire to explore: they are all kinds of candy colors! Umba sapphires tend to have a variety of inclusion types, but these are both pretty clean. The purple one is exceptionally clean, and the blue one has only a bit of crystal inclusions at one end, and they aren't even very distracting.
The purple one is done in a standard rectangular step-cut, while the blue one is done up in a cut-corner brilliant emerald cut design. Good cutting and polish done overseas with my partners.
