I don't know what everyone is so upset about. It's been known for some time that industrial diamonds are only cheaper up to a certain size after which they get more expensive.

Because most people have a soul and feel that human suffering is more important than time to produce a diamond.

Most consumers and industries don't want or need giant diamonds. Industry needs diamond dust for drills and files. For decorative jewelry, corundum (ruby and sapphire) is much cheaper to manufacture and almost as durable as diamonds.

Sure, it's going to be a lot more expensive and time consuming to make a 3000 caret rock than to mine one. But that 3000 rock is a curiosity to sit in a museum (or to be cut into smaller pieces), not a useful thing people will want to buy.

It says one carat, not 3000. That's a nomal size found in jewellery.

The article also admits that the industrial diamonds are a heck of a lot faster to make during the processes, and the 2-3 hours per caret for lab grown is specifically for gem quality stones intended to compete with gem quality mined diamonds.
