Condition

Very Good (appears clean with all stones intact; minor surface scratches expected on the underside/shank)

Description

Stunning vintage bridal set featuring a central round brilliant cut diamond solitaire nested within a matching 14K yellow gold interlocking wedding band. The guard band features a modern S-curve design with channel-set diamond accents that perfectly frame the center stone for a high-impact, tiered look.

Key Features

Total Carat Weight (TCW) likely exceeds 1.25 ct; interlocking guard design prevents spinning; classic 90s aesthetic currently trending in vintage jewelry markets.

Authenticity Indicators

Confidence: Medium. Look for '14K' or '585' stamps on the inner shanks. Use a diamond tester to verify stones are not Moissanite or CZ.

Flaws to Note

Possible rounding of prongs due to age; internal inclusions in diamond not visible without loupe; sizing may be difficult due to the interlocking nature.

Selling Guide

Where to Sell

eBay (for reach), Etsy (if marketed as 'Vintage'), or specialized platforms like Loupe Troop or DiamondBistro. Local pawn shops will only offer scrap metal + 10% stone value.

Selling Tips

Get a professional appraisal or GIA certification for the center stone to maximize value. Use macro photography to show the '14K' stamp and the clarity of the diamond under direct light.
