Fogh founded a silver workshop in Copenhagen, Denmark, in 1947 and made sterling jewelry, such as this grapes brooch topped with a ribbon. The shop close in 1978. The brooch is 2 1/2" by 1 1/2" and has a sturdy safety clasp. The brooch is marked Sterling SCF Denmark. I have added a sterling collar necklace and a sterling brooch converter. The necklace is 15 1/8" end to end with a gap of 2 3/8" and curved to fit around your collar bones. Fits 17" to 19". All the pieces can be used alone or the converter can be used with another brooch with a horizontal pin stem. Fogh is listed in Rezazadeh, Collectible Silver Jewelry, page 97. Excellent vintage condition.
