Vintage 10K Gold Diamond Ring · Three Stone Modernist Band · Size 7

This is a great little 10K yellow gold diamond ring with a very clean, slightly architectural design. The broad shoulders sweep toward a narrow central opening set with three petite diamonds in a vertical row. I like the contrast between the substantial polished gold and the tiny line of sparkle—it gives it a distinctly late-20th-century modernist feel.
 
The band measures approximately 6.25 mm across the top and gradually tapers to 2.6 mm at the back, making it substantial-looking from the front without feeling overly heavy.
 
The interior is stamped 10K along with additional marks. The underside reveals some of the ring's handmade construction, with recessed channels incorporated beneath the setting to help prevent moisture from collecting—a thoughtful detail that's hidden when the ring is worn.
