I kind of saw this a few threads back but....
I know we are only officially allowed to have diamonds and pearls in our quills, but if you could have any gem stone combo in your Quill, what would it be? I would love to have alternating Sapphires and Aquamarines... or straight Peridot (my Birthstone

)
I do love our crown pearl Quill though (and the one with a diamond at the tip)!
