Vintage triple Gold Chain Necklace

The "HONG KONG" mark indicates the item's place of manufacture. This type of marking is commonly found on vintage costume jewelry produced for export, primarily in the mid-20th century, from the 1950s through the 1970s. Details Origin and Era: Jewelry marked "Hong Kong" was widely manufactured during the period when Hong Kong was a major center for mass-produced goods, especially costume jewelry, for the Western market. The use of this specific mark on costume jewelry clasps is a reliable indicator of its age. Material and Value: The visible item appears to be costume jewelry with a gold-tone finish that shows some wear, which is typical of pieces from this era.These items are generally valued as vintage collectibles rather than for the intrinsic value of precious metals. Modern Markings:In contrast to vintage costume jewelry, high-karat gold from modern Hong Kong usually bears purity marks like "999" (for 24K pure gold) or international numeric standards like "750" (for 18K), often alongside a manufacturer's mark.
