Disenchanting a Legendary skin shard should give 1 rare gemstone. Ultimate skin shards should give 2

Seems logical to me

Pretty good idea imo. I already used my only Legendary (Teemo) so I could get the free Mystery Skin, but for all the ones I might get in the future that I already own it'd be great.

I'd say have legendary skins give a chance at a gemstone, and ultimate skins give a gemstone every time, but only after there are other things for gemstones to be spent on.

As it is now it would make getting hextech Annie too easy for people who spend real money on it, compared to free to play players. It's supposed to be insanely rare, after all, so maybe once other skins are added that use gemstones it could be a thing.

What are gemstones?

I think you should be able to exchange them for either the full essence or you may turn them in for gemstones instead.

IE: Legendary worth "X" Orange Ess. OR 1 Rare Gemstone. Ultimate worth either "Y" Orange Ess. OR 2 Rare Gemstones. *Ultimates may also be exchanged for "Y/2" + 1 Rare gemstone.

                             Say Ultimates are worth 1500 Orange Essence. You may also exchange them for 750 essence plus one rare gemstone.

I don't agree with that exact concept. It would decrease its rarity. Maybe if one Legendary Skin Shard would drop 1 gem fragment and need to get 3 gem-frags to craft 1 gemstone?

Gemstone should be sold for yellow/blue shards.

Also solve the "I have all champs/ blue shards useless" issue.
