7" A vintage 12k Gold Filled (GF) cabochon link bracelet like this typically holds a market value between $45 and $125. 

Key Valuation Factors

• Metal Value: "12k GF" (usually stamped 1/20 12k GF) means a thick outer layer of 12-karat gold is mechanically bonded to a base metal core. While more durable than standard gold plating, it cannot be melted down for scrap value like solid gold. Its worth relies entirely on its value as a collectible vintage jewelry piece. 

• Gemstones: The oval stones look like moonstones or opals. Natural stones will push the price toward the higher end of the spectrum, while faux glass or plastic cabochons stay on the lower end. 

• Condition: The bracelet shows some visible metal wear and discoloration on the gold links, which slightly reduces its collectible value.
