Square Diamond & Emerald Engagement Ring

The Tristan ring is an Authentic Art Deco engagement ring circa 1920! This square diamond and emerald engagement ring centers a GIA Certified 1.01 carat old European cut diamond of J color, VS1 clarity. The diamond is set in a platinum setting with a halo of calibre cut emeralds creating a square shape with a diamond set in each corner. On each shoulder, 9 diamonds are linearly set with some open metalwork details and hand engravings that continue down the shank. The gallery has gorgeous, scrolling filigree work. The ring is currently size 5.25 and can be resized to some sizes!

Why We Love It

An exquisite and very Deco piece seen through the linear themes and incredible craftsmanship! The diamond is bight and incredibly lively! The pop of the emeralds adds a definite uniqueness to this dream of authentic vintage!
