Art Deco Certified Diamond Engagement Ring of Platinum

A masterpiece of the Art Deco era (circa 1920–1930), this extraordinary engagement ring marries timeless elegance with exceptional craftsmanship. At its heart lies a 1.94 carat old European cut diamond (SI1 clarity, J–K color), its soft candlelight sparkle emblematic of the period. This center stone is EGL certified, ensuring its authenticity and quality.

The original platinum filigree mounting is an exquisite study in openwork design, adorned with 18 single cut diamonds (G–H color, SI2–I1 clarity) totaling an additional 0.28 carats. Together, the diamonds offer a combined weight of 2.22 carats. Subtle sapphire accents, original to the mounting, add a whisper of blue — these stones have not been tested for natural or synthetic origin.

This ring has undergone non-invasive XRF metal analysis confirming the purity of its platinum, alongside expert jeweler’s verification, ensuring both the historical integrity and lasting value of this piece.

Accompanied by its EGL diamond certificate and an appraisal summary indicating a retail replacement value of $21,830, this ring is a true collector’s jewel.

Currently a size 5.5 (resizing available for an additional charge), it weighs 3.7 grams and remains in excellent condition.
