I think you should consider Corundum, Quartz or Topaz. They all are
durable stones having a hardness of 8 and above on Moh's scale and
thus can be used for daily wear. Another reason, they all come in a
variety of colors, so you can get a wide choice of colors to chose
from.
One correction here. Quartz is the defining mineral for the mohs hardness
scale's 7. It is not as hard as corundum (sapphire,ruby, and a 9 on that scale)
or topaz.
