Knowledgeable collectors know how important a piece made Bettina Von Walhof is. I believe it was made in the early 1970s and who successfully has become a collector’s dream. Some of her pins have sold for as high as $1,000 in today’s market. She created this necklace with unusual cut crystal and elongated blue French glass. The necklace measures approx. 17” in length and is in excellent condition.
