A normal diamond pickaxe has 1562 durability so it may get you as much stone with that pickaxe. With Unbreaking III however, that may quadruple your mining count, or around 6248 stone.

A diamondâs cut is a very important quality to consider â a good cut truly brings out a stoneâs beauty, while a poor cut can make a stone with good color and clarity look dull. The cut of a diamond is one of its most important qualities, allowing its beauty to shine and downplaying any imperfections. The cut affects how light reflects from, enters and leaves the diamond. A good cut focuses light back out through the top or crown of the diamond and makes it shine. A poor cut can make a diamond â even one with good color and clarity â appear dull.
