What gemstone is harder than a diamond?

Is ruby harder than diamond?
Rubies have a hardness of 9.0 on the Mohs scale of mineral hardness. Among the natural gems only moissanite and diamond are harder, with diamond having a Mohs hardness of 10.0 and moissanite falling somewhere in between corundum (ruby) and diamond in hardness.
Is diamond harder than sapphire?
The only crystal harder than corundum (sapphire) is a diamond (cubic crystal structure).

When two mineral samples are compared, whichever mineral scratches the other is the harder mineral.
What’s the hardest gem?

Why are diamonds brittle?
Diamonds are no longer the world’s hardest substance “Whilst its cubic arrangement makes a diamond very hard, it is also somewhat brittle,” says Professor Phillips. “This is because there are weaknesses along the cubic planes.
