The Sherman Jewellery company was a baby boomer business i.e. it began operating in Montreal, Canada in 1947.
The "Jewels of Excellence" produced by Gustave Sherman's company have become so valuable because Sherman's goal was to use only the finest quality materials and stones available at the time. Sherman imported his "findings" as they are called, from the B.A. Ballou company in Rhode Island. The stones in Sherman pieces were made by Swarovski in Austria.
Another thing that set Sherman jewellery apart was the backings: rather than using chromium plating which was prone to peeling and chipping, Sherman used rhodium-plating. Rhodium comes from the platinum family of metals and is extremely durable. Durable is right! Some of my Shermans still have their original silvery shiny rhodium backing showing next to no wear. They look brand new!
Sherman's insistance on the highest quality made his pieces more expensive than other vintage jewelry of the time. But if they were expensive then, they have become even more so now. Sherman jewellery still fetches a high dollar today and is as much a collector's item as Miriam Haskell, Schiaparelli, Trifari, Schreiner, or Hobe or many others.
In future posts, I'll fill you in some more or just which pieces and colors are most in demand. While you're waiting, be sure to check out some of my gorgeous Sherman pieces at SHERMAN JEWELLERY SHOWCASE
