Marquise Diamond Ring Value Guide

This vintage American-made ring features the elegant marquise cut, a shape originally commissioned by King Louis XV to mimic the smile of the Marquise de Pompadour. This specific mid-20th-century piece showcases two navette-cut diamonds set in a classic 14K yellow gold band, representing a period where traditional royalty-inspired cuts met bold retro design.

What affects the value of Marquise Diamond Ring?

• The carat weight and clarity of the two primary marquise-cut diamonds significantly impact the $1,800-$2,200 valuation.
• The condition of the 14K yellow gold mounting, specifically looking for thinning of the band or worn prongs.
• Historical provenance or original jeweler marks from the 1950s-1970s era can increase collector demand.
• The symmetry of the marquise cuts, as poorly proportioned 'bow-tie' effects in the stones can decrease market value.

How to Identify Marquise Diamond Ring?

• Check the interior of the band for a '14K' hallmark, signifying the standard gold purity used in the United States during the 1950s-1970s.
• Examine the diamond shape for the characteristic elongated 'navette' silhouette with pointed ends and a curved middle.
• Look for the specific two-stone arrangement which distinguishes this mid-century design from traditional single-stone solitaires.
• Verify the setting style to ensure the points of the marquise diamonds are protected by V-shaped prongs, a common safety feature for this cut.

History of Marquise Diamond Ring

Marquise cut diamonds, also known as navette cut, have a fascinating history dating back to the 18th century. King Louis XV of France commissioned a jeweler to create a diamond cut that resembled the smile of his mistress, Marquise de Pompadour. This elegant and elongated shape became a symbol of royalty and sophistication. Over time, the marquise cut evolved, gaining popularity in various eras, including the Art Deco period and the mid-20th century, often set in distinctive designs like the ring shown.
