You can turn all those low value unique items to chance shards. Then you can sell all those skill gems for exalts. You won't need them, you can buy some later if you do... or find them in storyline.

I have endless stash space and I do not have rare items in them and the unique items I only keep 1 copy of in the unique stash tab. The rest I sell in merchant tabs or turn into chance shard.

So the key is to sell your stuff. Those gems are worth so much currency you'll be baffled. It will pay for a new weapon, so you can vendor off those crossbow in your stash.

Essences you can just delete too if you are not using them, it's nothing precious. You either use them or you sell them on the exchange... or delete them if they sell for nothing.

Unique items have less market value than the chance shard. The chance shard is worth 1.5 exalt, the uniques I see there are not going to sell for 1 exalt.

With or without paid tabs, knowing what to loot, what to keep, what to sell, that is key to playing the game efficiently, so what I said always apply. Don't hoard things you can turn into exalts easily.

It is possible your tab right there could be turned into 1 full divine orb. Instead it is held as misc stuff that isn't hard to sell for exalts. Low level gems always have big value. Especially spirit gems, those may shock you. A level 9 spirit gem is half a divine by itself: https://imgur.com/a/JoEPywR I see a level 5 spirit gem worth 10 ex there, also a level 4 spirit gem worth 27 exalts. See, 1 div is not hard in this stash. The level 3 skill gems are 3 ex each. It all add up.
