As there's no point in unsocketing low-tier gems, do the replacing on gems with up to stellar rarity. Always unsocket empowered gems, even if a gem is bad, and you don't need it, even if it's lvl 1 - you'll get emp. gem frags from loot collecting it, and then you can craft a stellar empowered gem box using 10 of these frags.
