Vapor deposit quartz on soft gems to make them durable
Some gems and minerals are beautiful but
can be easily scratched or abraded if used in
high contact jewelry like a ring. If the mineral
could be encased in quartz by putting it in a
vapor depositing oven, it would have a tough
clear coat. Example Violanes is a rare violet
mineral from Italy
which would be a
gorgeous gemstone if it were able to be

Epitaxy of quartz - current state of the art?
This suggests the idea would be harder than it looks. [pertinax, Nov 07 2020]

Method of coating surfaces with quartz
Patent - 1945 [kdf, Nov 07 2020]
By chemical vapour deposition [kdf, Nov 07 2020]
||Quartz crystals are produced industrially by deposition from aqueous solution.
||Good idea, Humans have been lacquering things from year dot.
|| But should quartz be the standard go to material. Carbon as a lacquer? The match of deposition chemicals and application environments for the needed mineral is going to a be game and a half. Maybe the Alloyotron can be adapted.
||Extrapolating, this could give rise to designer stones where amounts minerals are positionally doped in other minerals to make out of this world gems.
||It would make a lot more sense to encase them in colorless sapphire.
||Easier to stick a piece of sellotape over the top.
||See patent (link) for a method or process of
evaporating quartz to apply, by deposition.
resulting from thermal evaporation.
||By why settle for quartz or even colorless
sapphire? Chemical Vapor Deposition (CVD)
diamond coatings exist (link).
