There are Faded Velium Earrings and Rings of Brilliance, Security, Vigor, and Adroitness. Only Faded Velium Necklace of Security, Vigor, and Adroitness. Why no Brilliance? The same gems are used to make the items of Security, Vigor, and Adroitness. The Brilliance items all take the same gems: Oval Cut Velium Diamond and Round Cut Velium Diamond. But when i take those two gems and try to combine them with a Duo Velium Necklace (also used to make the other necklaces) I get: "You cannot combine these items in this container type!" What gives?
