I find that I usually receive more elemental gems when I play a character with a high focus stat, such as an Embermage. It is my personal opinion that the supposed RNG (there is no such thing as a true RNG in the programming world) on Torchlight II is actually biased depending on the amount and types of damage you have been receiving, and the stats you have assigned to your character. The game seems to prefer leaving your character with at least one weakness when it does its "random" drops. Instead I hoard the elemental gems that previous characters have gathered, since the random drops in the field are often missing the very one I need. I don't try to get elemental gems from the transmuter because the RNG seems to favor chaos and iron gems, as you have noticed. My primary focus when transmuting gems is to get those rare mana restore or hp restore gems. If it's upgraded at all, it's to a chaos or iron gem of the same level (since Torchlight II considers those to be upgrades). In my experience, that result is usually a gem of the same level as the gems you put in. So, in Torchlight II, the transmutation of any 3 gems will give you a random result. There is even a hint that appears on-screen in Torchlight II telling you to not save your gems and go ahead and use them when you get them. They wanted to discourage people from hoarding gems, and overly upgrading them.

Once again they can remove gems from sockets, by either destroying the equipment to recover the gems or destroying the gems to free up the item's sockets. a level 36 gem will not fit into the sockets of a level 27 armor/weapon). My best guess is that it is itself a craftable item but I have no idea what the recipe might be. A gem can only fit into the socket of an item that is equal to or higher than its level (i.e. The tooltip for the Angelic Soul says to transmute it with a legendary set item and something called a Soul Stone, which I cannot find at any of the Synergies-specfic vendors (though it is possible I have overlooked a vendor somewhere). Unique items usually have at least one socket. The number added is random from 1 to the maximum number that item type allows. A transmutation recipe can add sockets to an item that initially has no sockets. A specialized, wandering enchanter can add up to two sockets to each item. A piece of equipment may have anywhere from one to six sockets, depending on the item.
