Though the Jeweler Items in several [[slots]] can always remove a gem from an item (for a fee) spawn with one or more sockets, but there is no way to add additional sockets to an item in Diablo 3. (Gems can also be removed from items by salvaging, though this permanently destroys the item.) Reaper of Souls added Only the [[Mystic]] Artisan, who added in Reaper of Souls, can [[enchant]] items, rerolling one of the affixes and giving players a chance to potentially add a socket by rerolling one of the sockets via [[primary affixesenchanting]]an affix. (The [[Secondary affixesJeweler]] can never be remove gems from sockets.) This can be , for a difficult and expensive taskgold fee, sometimes requiring many rolls in D3 and prayers to the gods of [[RNG]]RoS.

** Several legendary items in In [[D3v]] [[Ice Climbers]] boots and [[Diablo 3 vanillaTasker and Theo]] held gloves had a socket in other item slots that can not otherwise have sockets, and the [[slotsManticore]]but these are not found crossbow could spawn with two sockets. These irregularities were eliminated in the [[Loot 2.0]] version of those legendaries. ([[Ice Climbers]] boots and [[Tasker and Theo]] gloves.)

'''Gem removal''' is done via the [[Jeweler]]. Gems cost gold to remove from items, or can be removed for free by [[salvaging]], which destroys the item but not the gem(s). The costs to remove gems have been tweaked repeatedly, and costs were considerably lowered for high end gems in Reaper of Souls in [[Patch 2.0.5]]. Gem removal prices, per gem, as of that patch:* [[Marquise]]: 50k* [[Imperial]]: 100k* [[Flawless Imperial]]: 150k to 125k gold* [[Royal]]: 250k to 150k gold* [[Flawless Royal]]: 500k to 175k gold '''Gem upgrade ''' costs have been tweaked several times. The entire system received an overhaul for [[D3v2]], with much lower gold costs and an almost total removal of material components. It's much cheaper to make the highest level gems in [[Reaper of Souls]] than it was to make them in [[Diablo 3 vanilla]], though the number of gems is the same, with 2 > 1 until Flawless Square and 3 > 1 at all levels above that.
