Marquise Diamond Wedding Set Value Guide

This 14K yellow gold Marquise Diamond Wedding Set represents a quintessential bridal style from the late 20th century, specifically the 1980s and early 1990s. The marquise cut, or navette cut, is highly collectible for its historical lineage dating back to King Louis XV and its ability to create an elongated, elegant look on the finger.

What affects the value of Marquise Diamond Wedding Set?

• The carat weight, clarity, and color grade of the central marquise-cut diamond significantly impact the $1,850-$2,000 valuation.
• The total weight of the 14K yellow gold and the presence of any additional diamond accents on the matching bands.
• The condition of the prongs, particularly at the vulnerable pointed tips of the marquise diamond.
• The provenance and original documentation, such as a GIA report or original retail appraisal from the 1980-1995 era.

How to Identify Marquise Diamond Wedding Set?

• Check the interior of both bands for a '14K' hallmark indicating the gold purity standard common in the United States.
• Examine the center stone for the distinct elongated 'navette' shape with pointed ends characteristic of the marquise cut.
• Verify that the wedding band is contoured or notched to fit flush against the marquise-cut engagement ring setting.
• Look for the specific yellow gold setting style popular between 1980 and 1995, often featuring thicker bands or channel-set accents.

History of Marquise Diamond Wedding Set

The marquise cut, also known as the navette cut, originated in the 18th century when King Louis XV of France commissioned a jeweler to create a diamond shape that resembled the lips of his mistress, the Marquise de Pompadour. This specific style, featuring a yellow gold band with diamond accents, became a staple of bridal fashion in the late 20th century.
