A suggestion to be able to make rings out of a cut gem of starburst quality with a silver bar+starburst gem, a player can only wear 1 ring at a time.
1. The ring can show on the hand of the player and is of course either shiny blue/pink/green/amber coloured.
2a. Excessive carat size allows for a ring to have 1-2 artifice slots
2b. Excessive carat size & color type gives the ring a special ability. The ability can be related to the corresponding stat boost
ex:(blue gem = weaving special ability)
Obviously this would end up limiting what can be done with the rings in that they can't be put into combat oriented builds such as having artifice slots.
If the gem is not high enough carat size then the gem will be dull in color when equipped and will have no artifact slot(2a) /special ability(2b)
