Antique 10k White & Yellow Gold Stick Pin with Pearl

This is a beautiful, elegant antique pearl stick pin made of 10k white and yellow gold. The top is white gold, and the pin part is yellow gold. The stamp mark has worn down considerably, but it can still be read as 10k. There are signs of wear and use. Overall, the piece is in very great shape. Unfortunately, I do not know whether the pearl is natural or cultured. Likely made around the 1910s-20s. Approximate Length: 2.5 in. Approximate Pearl Size: 7mm (could be less) Approximate Weight: 0.9 grams
