Casting crystolecules

Casting crystolecules. Or more accurately "in nano-mold crystallization".
The basic idea here is to use a mold for that inside has surfaces that temlates crystal seed formation
that initiate crystallization but also a compartment with small enough openings that terminate crystal growth (presumably).
This only works for in-solvent-crystallizable gemstones.
In particular clearly excluding diamond and it's hexagonal version lonsdaleite, also likely excluding moissanite and many semiconductor diamondoid structure gemstones.
Some salot of oxoacid gemstones may be viable. Iron based gems like hematite, magnetite, pyrite seem viable.
Questions
- limits on atomic precison in surfaces (and in the interior crystal structure)
- removability of the mold
Nature of the mold
- In early incremental path technology this may protein based molds.
- In advanced gem based APM the molds themselves could possibly be made from crystolecules.
