Talk:Disgustedorite's Gem Seed AU/Successful Crosses/@comment-27567123-20170121061831/@comment-25175729-20170121072214

Pearls have completely different incubation conditions from most other kinds of Gem, so it would be impossible in any natural environment. But if an artificial environment could be made that can incubate the seed, the result would be something resembling a version of Lapis Lazuli with significantly more calcite than usual, calcium carbonate integrated with almost every aspect of the stone, and a thin outer layer of nacre.

I'm not sure such a thing even has a name--it's impossible in the real world, too.
