This is a fine 1970s vintage necklace collar made by Jacob Hull for Buch and Deichmann. Hull designed one of a kind sterling jewelry at his studio, and also designed limited runs of silver and gold plated pieces produced by Buch & Diechmann, which were marked B+D and were sold in the high end Danish department store Illums Boligus. This particular circlet necklace is marked inside Jacob Hull B+D Denmark. The 3 toed pendant that hangs from the center loop is marked 925 for sterling silver on the heavy connecting ring. This perplexes me a little because Hull's B+D pieces were typically plated rather than solid sterling, but this piece is testing as sterling silver on all parts. However it is possible that the circlet portion may be heavy silver plate as I chose not to dig into it to test below the surface. It is also possible that the pendant portion might not be original to the necklace. It is certainly of appropriate scale and style, but I haven't found one of the same design by Hull yet. So judge this for yourself.
The necklace will fit a woman's small to medium size neck. The opening gap measures 3". I have a 13.5" neck and I can wear this necklace but a larger size would have difficulty. The circlet has a maximum width of .5" in front. The pendant hangs down an additional 2" in front.
Condition: There is a small manufacturing flaw/split on top center front of the circlet, but no danger of further splitting.
