Uhh assuming they fix the gemmed items shit this is a list of possible cuts (maybe not complete)

Oblique/Cabochon = Armor
Rhombic/Trillion = 1h weapon
Oval/Teardrop = 2h weapon (i think not 100% sure)
All stats except for "Immunity" (to all) && immunity to all magic% and immunity to all physical% scale with gem level.
