Classic and elegant and always in fashion. Originally created by the Forstner jewelry company in the 1930s and 40s this was and still is a piece to be worn by a modern woman. The springy tubogas or gas pipe technology was formed from a pair of interlocking gold strips wrapped tightly together to form a flexible necklace or bracelet without any soldering. Silky smooth and so easy to wear. This bracelet is beautiful on its own or equally great in a stack. Excellent condition with a push clasp and original safety chain. Marked Forstner 14KT. 33.7 Grams. 7 inch length but is slightly stretchy.
