[Looking4] Ruby cushion cabochon

I am looking for a 8mm square cushion cabochon ruby for a custom
ring, My customer has her heart set on ruby. The ruby material
should be semi-opaque or translucent but with good bright ruby color.
Treatments are acceptable as long as they are disclosed, and the
budget is under $400.00. I would be open to hearing from someone
willing to custom cut the stone for me, from maybe a 10mm round
stone sourced by myself or the cutter.

Thanks!
Amy
