This necklace is silky smooth and brilliant in color anyway you look at it. A fashion statement of the 1940s that is very fashionable today, the gas pipe or tubogas necklace is flexible , hollow and tubular. It stretches and is quite flexible. It sits as a collar on the neck and is adorned at its center with a platinum and diamond station set with 2 rows of modern pave set brilliant cut diamonds that are approx. .50 Cts in total. The necklace has a good deal of stretch to it so the 14 inch length is not the total length as it has quite a bit of give. The collar is gorgeous as a stand alone piece on your neck or with other chains stacked beneath it. A true statement necklace. No markings but tested. 36.7 Grams. 14KT Gold.
