Anything is possible but the cost of trying to make lenses out of material almost as hard as diamond would be prohibitive.

Man made sapphires used for jewelry are sometimes given a coating of diamond to make them more durable and give them a better appearance. Sapphire is better than what they use now for displays, but it will still scratch.
