Description
An enchanting three-stone ring crafted in 18K yellow gold, featuring a vibrant green center emerald flanked by a rustic clear diamond and a deep pink ruby. Each stone is cradled in a decorative, scalloped bezel setting that adds a vintage architectural feel to the piece. The contrast of the three primary colors against the rich gold creates a regal yet bohemian aesthetic.
Key Features
Scalloped milgrain bezel settings, mismatched side stone shapes (round/rose vs pear), and a high-chrome green center emerald that serves as the focal point.
Color & Finish
Rich buttery yellow with a high-polish finish on the shank and a textured, granulated/milgrain finish around the gemstone bezels. Minor surface patina consistent with light wear.
Hallmarks & Stamps
Not clearly visible in the image, but typically located on the inner shank. Likely includes a '750' purity stamp and potentially a maker's mark or assay office symbol.

Not applicable; continuous circular ring band.
Chain & Links
Solid, slightly rounded or 'D-shape' band profile. The shoulders are integrated into the decorative collet settings through precision soldering.

Authentication Indicators
Saturated yellow color of the gold; bezel construction quality; genuine gemstone characteristics including visible natural inclusions and light refraction.
Origin & Maker
Likely European (Italian or British) or a boutique independent jeweler. The craftsmanship suggests bench-made quality rather than mass-produced casting.
Era & Period
Contemporary/Artisan with Georgian/Victorian Revival influences. The scalloped collet settings and mismatched stones mimic 'Dearest' or 'Acrostic' jewelry of the 19th century.
Age Estimate
Likely 2000s to present. While the style is historical, the precision of the facet edges and the metal brightness suggest modern production.
Cultural Significance
Represents the 'Trinity' or 'Past, Present, Future' symbolism in three-stone rings, updated with a modern, colorful gemstone palette.
Condition Notes
Very Good. The stones appear secure; minor surface scratches on the gold shank and slight inclusion visible in the emerald (typical for the species).
Value Estimate
Retail replacement value between $1,200 - $2,200 depending on the specific clarity of the stones and brand provenance. Melt value is secondary to the gemstone and design value.
Care & Maintenance
Clean with warm, mild soapy water and a soft brush. Avoid ultrasonic cleaners and steam as Emeralds are porous and often oil-treated, making them sensitive to heat and chemicals.
