Looking to Buy A Stuller Band To Match My Stuller Ring

Hi. Looking to buy a Stuller band to match a ring I just bought. From my research, the style number would be 50293. I'm running into a problem that a vendor doesn't want to help me unless I buy the engagement ring (which I already have) from them. I think the style might have been discontinued, but I did find it on Moissanite Co and inquired about it and they have it available to order, but once again they don't want to sell it to me unless I buy the engagement ring from them; even though I am existing customer and bought another ring from them for $1600.

Does anyone know a jeweler who is willing to order this for me at a fair retail price? Thank you.
