Hi Dave,

Thanks for the reference.  Maybe someday Swiss Jewels will "open up"; and
list prices.

I see that Swiss Jewels corrundum balls are the same grade 25 sphericity
(roundness) as Small Parts Inc., sells.
I'd guess Small Parts Inc., is abit cheaper.

Take care, Meredith

Swiss Jewel company (Philadelphia, PA http://www.swissjewel.com/).  sells all sorts of forms in glass, ruby, and alumina.  It has been many years since I used them so I can't give current prices.  They do sell to industrial customers, and it may work best as a group purchase.
