Vintage 10K Art Deco Two Tone Gold Cufflinks

This is luxury from a century ago! Art Deco cufflinks from the 1920s-1930s, made of solid 10K gold. Marked on the back, "C-10K". They feature a geometric design with circular and line etchings. One other site has a similar pair and they call them "Engine Turned". I think they look a bit like speeding through space in a movie. Gorgeous in yellow and white gold, these are in excellent condition. Together they weigh a whopping 5.46 grams! Seriously chic and perfect for special occasions, weddings, a super fine gift, or for a serious collector. They measure just under 1/4" wide by just over 1/2" long.
