I don't think the next application of lab grown diamonds will be rings and necklaces: https://www.extremetech.com/extreme/212422-this-new-high-power-diamond-laser-can-cut-steel https://www.extremetech.com/extreme/212422-this-new-high-pow... It's weird. The most popular shape of diamond is about to become a ~10 to 50cm long rod, not even polished (not very shiny at all, it's somewhere between white and light grey and looks like it's covered in fine dust, like a natural diamond in a regular shape).

(this is likely made by buying such laser rods and cutting them up) (corundum is the name of the material, Rubies and Sapphires are the forms of it. These will be cut rubies. They're quite spectacular looking)
