What affects the value of Marquise Diamond Solitaire Ring?

• The clarity and color grade of the marquise-cut diamond are primary drivers for the $500-$550 price range.
• The karat weight and total mass of the gold band affect the intrinsic scrap and resale value.
• The symmetry of the marquise cut, specifically the absence of a dark 'bow-tie' effect in the center of the stone.
• The structural integrity of the prongs and the presence of any original jeweler hallmarks or certifications.

How to Identify Marquise Diamond Solitaire Ring?

• Look for the characteristic football-shaped 'navette' cut with pointed ends and a curved middle.
• Check the interior of the gold band for hallmarks indicating metal purity, such as 14K or 18K, common in US-made rings from this era.
• Examine the setting for V-shaped prongs, which were specifically designed during this period to protect the diamond's fragile points.
• Verify the era by the band's construction, which typically features the polished, minimalist aesthetic prevalent in late 20th-century solitaires.
