Does anyone remember the bunch of PR around Diamond Foundry? https://qz.com/630512/would-you-propose-with-a-diamond-grown... was on HN. I've seen their diamonds and they seem quite nice, from the naked eye, to me. Their direct-to-consumer company is here: https://vraiandoro.com/ and as far as I can tell, their diamonds look nice and like other diamonds, at least from the outside.
Are diamond foundry's prices an accurate idea of the cost to manufacture lab diamonds? I was surprised by what seem like only slight discounts over natural diamonds.
