Looking for manufacture of unusual bezel sizes

Good morning to all !! I have recently purchased some very
interesting vintage glass. I have all the designs completed and can’t
find the correct bezels to fit. Seems the vintage stone and cabs are
in the 9 , 11, 15. mm size range. Same for the ovals and rectangles.
Can some one direct me to manufactures of sterling silver bezels in
unusual sizes? Thank you !!! Be well Helen , Silver Thumb Studio, Ct.
