Vintage 10K 18K Gold Diamond Ring · Geometric Three Stone Statement Ring

A striking vintage diamond ring with bold geometric styling, crafted in a combination of 10K and 18K gold. The substantial tapered shoulders frame a raised square centre, accented with white gold and set with a sparkling round diamond. Two additional diamonds are tucked into triangular white gold settings on either side, creating a wonderfully architectural design.
 
The ring has a distinctive Art Deco revival influence, with stepped lines, strong symmetry and a handsome low-profile design. Its substantial proportions make it equally appealing as a statement ring, pinky ring or unconventional diamond ring.
 
The centre diamond measures approximately 3.9 mm, while the two accent diamonds measure approximately 2.65 mm each. All three stones have been tested as diamonds with a Presidium tester.
 
The inside of the band is stamped 10K 18K along with a maker's mark. The markings indicate that both 10K and 18K gold have been used in the construction, likely corresponding to the contrasting components of the design.
 
A distinctive estate piece with beautiful vintage character and a particularly appealing geometric profile.
