This finely wrought chain was purchased in the early 1990’s and seldom worn – I am not fond of necklaces. With the exception of wear on the spring ring (visible with a magnifying glass) I cannot find any flaws. The makers mark appears to be a series of lines in a pyramidal shape. It is clearly marked 14k and Italy. 1MM x 16”. I do not clean vintage or fine jewelry. Non smoking home. Shipped with USPS Ground Advantage
