mass update crystal -> crystal_(stone)
mass update diamond -> diamond_(stone)
mass update emerald -> emerald_(stone)
mass update pearl -> pearl_(stone)
Just to disambiguate any possible tagging issues I'd like to propose that we conform all gemstones with a *_(stone). I will gladly go around to remove any confusing statements left in each gems wiki entry to make the whole process a successful swap over should this bulk update request be approved.
EDIT: The bulk update request #1906 (forum #153429) has been approved by @NWF_Renim.
