While not strictly speaking a jewel, this is a fantastic and very unique Schreiner belt made entirely of rhinestones. All stones are reverse set, a feature often associated with Schreiner pieces, and set in gunmetal. Another Schreiner feature is the use of open backed stones. Signed Schreiner New York. This measures 33-1/2 inches from end to end, so you’d have to be somewhat slim to wear it but how perfect over a black sheath dress, a la Mad Men at a Christmas party! In her book “Costume Jewelry Price Guide”, Harrice Simons Miller interviewed Terry Schreiner, who noted that all-jewelled belts were produced in the 1960s and were they to be made today, would cost $2,000-$3,000 because of the cost of the Swarovski stones used.

So happy to have found this page. I have the same belt with the exceptions of silver metal finish and completely clear stones. It’s spectacular
Thanks! I’m a big Schreiner fan too!
I was looking to purchase the book you mentioned, finding a few and want to buy the correct one. Is it possible I could get the ISBN number from you?
Regards
Which book are you referring to?
Mentioned “ “Costume Jewelry Price Guide”, Harrice Simons Miller interviewed Terry Schreiner,” I am getting mixed titles when google and/or curious if there is more than one edition which maybe has the belt referred to above in this post “Schreiner belt”
It was published in 1994 and is likely out of print. ISBN is 0-380-77078-4.
