Details: This is an ultra chic 14k gold collar necklace that takes its Italian name - Tubogas - and inspiration from the specific type of piping used for gas lines. The collar closes with a hidden secure box and tongue clasp. Textured and flexible this is a very bold and fashionable look. 

This striking collar is shaped from a pair of interlocking gold strips wrapped tightly together,  forming a flexible and hollow tubular necklace that requires no soldering. Originally done in the 30's/40's it was popularized by classic Italian jewelers, Bulgari and Van Cleef & Arpels. This sleek design is a modern classic. 

Measurements: The total weight is 43.5g.
