1.89 Carat Old Mine Cut Diamond and Tapered Baguette Platinum Engagement Ring
About the Item
A refined tribute to antique beauty and timeless design, this exquisite platinum engagement ring features a beautifully proportioned Old Mine Cut diamond weighing 1.89 carats total. At the center, a 7.4 x 7.29 mm cushion-shaped Old Mine Brilliant dazzles with its distinctive faceting and soft, romantic glow — a cut beloved for its vintage character and warm fire.
Graded F color and SI2 clarity, the diamond is completely eye-clean, offering crisp brilliance and an elegant presence on the hand. Flanking the center stone are two tapered baguette diamonds, adding structure and a subtle Art Deco flair to the overall silhouette.
The setting is handcrafted in platinum, with smooth, clean lines and low-profile prongs designed to highlight the center stone’s charm without distraction. Whether chosen as an engagement ring or a once-in-a-lifetime gift, this piece is effortlessly elegant and rich in character.

Antinori Fine Jewels
Nodding to tradition while embracing a tech-forward ethos, Antinori Fine Jewels has ascended to prominence with its collection of world-class diamonds and colored gemstones.
There is no paterfamilias shuffling in the background at the jewelry company, a 10-year-old luxury brand based in Rome that specializes in engagement rings and statement rings set with jumbo-size diamonds and colored gems of the highest order. Although all four founders — husband-and-wife duos Alessandra Antinori and Andrea Landolfi, and Alessandro Cutelli and Silvia D’Ambrosio — hail from small family jewelry businesses founded in the 1970s, Antinori Fine Jewels is an independent force. The dynamic quartet of mindsets and skill sets is united by a single goal: to take the business of making and selling high-end Italian jewels out of the past and into the present.
Before launching Antinori Fine Jewels, Alessandra Antinori — the company‘s international sales director and spokesperson — and her cofounders spent years acquiring experience in the jewelry centers of Rome.
“We have inherited from our parents the right connections with local jewelers, gemologists and artisans who still craft jewelry as they did one hundred years ago,” she tells 1stDibs.
The foursome is eager to develop and embrace any innovation that will help enrich their customers’ experience — and make the most exquisite examples of Italian jewelry readily available to a global audience.
