so I have gotten into the SU fan universe and created my own gem sona, named emerald. Now I imagine that diamonds have gems that are quite dispensable, and some that are more worthy, but I also think that all diamonds had a triad of gems that served a purpose. Mine were rubies, sapphires, and emeralds, where sapphires can see the future, emeralds can predict how possible that future is, and rubies work to either preserve the future, or change it to their diamond's wishes. so my emerald can calculate the probability of anything, but she can't control her powers so she was downgraded to a gem shatterer (assassin) to harness her calculating skills. her second eyes open when she is calculating. Her gem is on her back, and her weapons are 2 one-handed swords.
