Lab diamonds are used in huge quantities (ie. By the bucketful ) for making cutting tools like saws and drill bits.

I believe the main difficulty is making large and pure diamonds. Making small low purity diamonds is cheap and easy to scale.

That was ten years ago. Today, lab grown diamonds are cheaper than natural at any size or quality, which is why the diamond cartels are sh*tting little bricks that are almost as hard.
