Authentic Antique Art Deco Ring in Solid 10K White Gold with Synthetic Ruby Cabochon

Offered here is a genuine Art Deco era ring dating to the 1920s–1930s, crafted in solid 10K white gold and set with a rich red synthetic ruby cabochon. This striking vintage ring features exceptionally well-preserved hand engraving, a hallmark of quality workmanship from the period.

The bold geometric design, substantial gold weight, and vibrant ruby make this an outstanding example of early 20th-century jewelry—equally suitable as a statement ring, collector’s piece, or historically accurate vintage wear.

🔹 Stone Details

• Stone: Synthetic ruby (lab-grown corundum)

• Cut: Cabochon

• Color: Deep red with pink highlights

• UV Reaction: Glows pink under ultraviolet light (typical of early Verneuil rubies)

• Condition: Excellent, no chips or cracks observed

Synthetic rubies were widely used during the Art Deco period and are considered period-correct, durable, and collectible in their own right.

🔹 Metal & Construction

• Metal: Solid 10K white gold (acid tested)

• Markings: Mark present but worn, consistent with age

• Acid Test Results:

• 10K acid: no reaction

• 14K acid: scratch remains, shifts warmer in tone

• 18K acid: scratch disappears

• Alloy Type: Early nickel-based white gold (pre-1940s)

🔹 Measurements & Weight

• Ring Size: 4.5

• Total Weight: 5.28 grams

• Face Width: 15.8 mm

• Rear Band Width: 2.8 mm

The ring has excellent weight for its size, indicating solid construction rather than thin or hollow gold.

🔹 Condition

Very good antique condition. The engraving is unusually crisp and deep, showing minimal wear and no evidence of aggressive polishing. Light surface wear consistent with age only. Please review all photos carefully as they form part of the description.

🔹 Era & Style Notes

• Period: Art Deco (circa 1920s–1930s)

• Style: Geometric, engraved, signet-inspired

• Originally marketed as a gentleman’s or unisex ring, now highly sought after by collectors
