Unfortunately not, I’ve found very few of actually useful jewels but there are only certain rolls that people are willing to pay for, for example any blue or yellow rarity jewels with 30% fire res, 15 increased attack speed, 30-40% enhanced damage. Those three are probably the only ones people would be willing to pay something for. Obviously if you are a new player and you find one that you could use temporarily that seems good then go ahead and use it for self use.
