This is a circa 1900 Arts & Crafts pewter brooch set with a round opal-like ceramic pottery cabochon in the manner of Ruskin pieces, but due to the closed back setting the ceramic can't be checked for markings. This brooch came from England and may well be made by Ruskin, though it's identity can't be confirmed. It certainly bears all traits of that manufacture. It is a simple square brooch with hand chased pewter top surface and brass back. The back has a simple old fashioned pin stem with T hinge and C clasp. The round center cabochon is a hand made ceramic pottery piece glazed in shades of pale blue with a little bit of rust color around the edges.
The English Ruskin Pottery was founded in 1898 by Edward R. Taylor, and located at 173-174 Oldbury Road Smethwick, Sandwell, West Midlands. It was named after the artist, writer and social thinker John Ruskin. Their production was famous for their innovative glazes. The studio closed in 1935 and the formulae for the glazes was destroyed so their unique products couldn't replicated.
This brooch measures 1.25" square. The center stone measures .75" in diameter.
Condition is good.
Brooches like this are excellent examples of the type of jewelry produced during the Arts & Crafts movement, with an emphasis on handicraft instead of the use of precious metals and stones.
