Marquise Cut Diamond Solitaire Pendant Value Guide

What affects the value of Marquise Cut Diamond Solitaire Pendant?

• The carat weight and clarity grade of the central marquise diamond significantly impact the $1,650-$1,800 valuation.
• The quality of the 14k white gold setting and the integrity of the multi-prong security.
• The symmetry of the marquise cut, as uneven 'wings' or points can decrease the aesthetic and market value.
• The presence of original documentation or a grading report confirming the diamond is a natural stone.

How to Identify Marquise Cut Diamond Solitaire Pendant?

• Verify the '14K' hallmark stamped on the pendant bail or the reverse of the setting to ensure gold purity.
• Examine the marquise diamond for the characteristic 'bow-tie' effect, a dark shadow across the center common in this cut.
• Check for a multi-prong setting, typically featuring V-prongs at the points to protect the diamond's fragile tips.
• Inspect the diamond under magnification to confirm natural inclusions consistent with stones from the late 20th century.
