SmartHarvest
It's hard to see the particles in a still photo, but the hoe is fully down in attack mode (cursor on tender young crop, center), and the plant isn't breaking. Unenchanted, the ruby hoe would have torn through the plant and several blocks of dirt
Blocks
The ore (set in netherrack for comparison) and a block of ruby patterned after the block of emerald (shown in creative mode).
