the title is well written, it is a dillema

even if your intention is good, to make everyone can have para/eyes again, probably most people will sell them for gold instead of using them, so the goal to balance everyone by letting players using para/eye will not be reached. and if they force it by making the gems untradeable, it will only re-live the scam with para gems. and in the end still, OPs with limited edition items will still be there. so, nothing will change

if sts wants to stick with the jewels, they need to force it to phase out, by making it stop scaling up on next cap and probably a limited time exchange of gems to jewels

and anyway they need to increase the chance for looting sns
