ISO Emerald Moissanite Ring Please!

I am in search of an emerald cut (preferably F1) moissanite ring.  I’d love a halo, but I am open to other styles!  The stone can be either 7x5 or 8x6. I am a size 5.5, so the ring needs to be able to be sized up or down to that, and it needs to be white gold (I might would consider rose gold).  Thank you!
