This gorgeous Lily is 9mm with a gem space of 1.3mm/0.01 Carats as of now. I think it would still look great if it were scaled up in the slicing program of your preference. this of course will change the space size for the gem. A Garnet would look great in the center, but I won't stop you if you want to put another gem there. Please, make it your own. I'm selling this for 35 dollars.
