Marquise Cut Emerald and Diamond Ring Value Guide

This 1980s-era bypass ring is a quintessential example of late 20th-century American commercial fine jewelry, prized for its finger-elongating marquise-cut natural emerald. Its 'moi et toi' inspired split-shank design in 10K gold reflects the transition from bold vintage styles to the more delicate aesthetic of the early 1990s.

What Is Marquise Cut Emerald and Diamond Ring Worth?

The typical price range for Marquise Cut Emerald and Diamond Ring is $160 - $175 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The saturation and clarity of the natural green emerald significantly impact the $160-$175 price range.
• The total weight of the 10K yellow gold band, as gold melt value provides a baseline for the ring's worth.
• Overall condition of the marquise cut, as these pointed stones are prone to chipping at the tips if not handled carefully.
• The presence of original hallmarks and the integrity of the bypass shank's structural shape.

How to Identify Marquise Cut Emerald and Diamond Ring?

• Check the inner band for a '10K' hallmark, signifying the gold purity standard common in US jewelry from this era.
• Examine the emerald for natural inclusions, which distinguish it from the synthetic stones often found in lower-end costume pieces.
• Verify the bypass or 'moi et toi' construction where the two ends of the 10K yellow gold band overlap rather than meeting in a straight line.
• Inspect the diamond accents flanking the central emerald to ensure they are prong-set rather than glued.
