Well this one is closer to a gem than the other one but those powers make little scenes

Shape shifting should not be listed as a power, any gem can do that, as for controlling blood and gemshards that is a little too over powered. Gems normally have a medieval weapon and/or some elemental power.

As for the gem, bloodstone is not solid red like that, it's more of a greenish color with red speckles. This one should be called red spinel
