What affects the value of Art Deco Diamond Eternity Band?

• Total carat weight and the clarity grade of the continuous diamond row significantly impact the $2,200-$2,400 valuation.
• The condition of the platinum channel walls; thinning or metal fatigue from previous resizing can lower the market price.

• Historical provenance or original jeweler marks from prominent 1930s American makers.

How to Identify Art Deco Diamond Eternity Band?

• Examine the setting for the signature Art Deco channel-set technique which secures stones without visible prongs.
• Verify the presence of both step-cut and round brilliant diamonds, a specific combination used to enhance light play in this era.
• Inspect the side profile for hand-engraved wheat or scroll patterns often found on authentic platinum bands from 1930-1940.
