[Looking4] Replacement diamond for a repair

Hey all, I do occasional lapidary work for a jeweler, who asked me if
I could find a replacement stone for a repair. Does anyone have or
know anyone who might have a diamond baguette 1.90mm x 3.75mm with
grooves for an invisible setting? He didn’t mention a grade but at
this point I think he would be thrilled to find one that fit.

Thanks, Jim Doherty
