Why are lab grown diamonds still priced in the 1000+ range. Does it actually cost that much to manufacture. Making up research cost? Just high profit margin?

TL;DR They have very similar cost structures as mined diamonds (rough [mine vs. grow], polishing, grading, etc.), plus the R&D and failure/success rates.
