These accessories are characterized by a base metal, typically brass or copper, that has been mechanically bonded with a layer of gold. The gold layer, while not solid gold, provides the appearance and much of the durability of solid gold at a more accessible price point. These items were particularly popular from the late 19th century through the mid-20th century, offering a cost-effective alternative to solid gold jewelry.
Their appeal lies in their combination of aesthetic value and relative affordability. The gold layer, being significantly thicker than that found in gold-plated items, offers greater resistance to wear and tarnish, ensuring a longer lifespan. They also hold historical significance, reflecting the styles and craftsmanship of their respective eras, making them desirable collectibles.
