Thnx, I get new ideas about the bgThe background is ruining the entire icon. A faint glow around the ring, in a matching rainbow color or bright one will do better than a black background with weird green lines.
Also, try to surround the gems with thin dark lines, to make them stand out, and also give them heavier highlights, color variations and shadows. Right now, they are quite plain.
hmm ring of infinite gems? i think that you should rename it to ring of 12 gems xD
anyway good icon!! 4/5 but it doesn't really look like the one on the reference picture...
