Vintage 12K Gold Filled Labradorite Brooch Large Oval Labradorite Cabochon Pin Signed J.C. Co Mid Century Statement Jewelry

Striking natural labradorite and classic mid-century American craftsmanship come together in this impressive vintage 12K gold filled brooch. Centered by a substantial oval labradorite cabochon, the stone displays the captivating optical phenomenon known as labradorescence, revealing vivid flashes of royal blue, cobalt, teal, and icy blue as it catches changing light. Natural mineral veining and inclusions create a one-of-a-kind landscape within the stone, ensuring that no two examples are ever exactly alike. The simple polished gold filled mounting was thoughtfully designed to showcase the remarkable beauty of the gemstone without distraction, allowing its color play to remain the focal point.

The reverse is clearly marked "1/20 12K G.F. J.C. Co.," identifying the mounting as genuine 12-karat gold filled construction. Measuring approximately 1 13/16 inches long by 1½ inches wide, this substantial brooch offers exceptional presence while remaining elegant enough for everyday wear on a jacket, sweater, scarf, or dress. Acquired from my late uncle's long-held collection, it represents the enduring appeal of quality American gold filled jewelry paired with one of nature's most fascinating gemstones.

Condition is very good vintage condition with light age-related surface wear to the gold filled mounting consistent with careful ownership. The natural labradorite exhibits inherent mineral inclusions and veining characteristic of genuine stone, while displaying beautiful blue flashes in changing light. The pin and clasp operate properly, and the gold filled finish retains a warm, attractive luster.
