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.

- Golconda Type IIa 2.36 Carat Diamond Flanked Solitaire Ring, circa 1950Located in London, GBGolconda type IIa diamond flanked solitaire ring. Set to centre with a Golconda type IIa octagonal emerald-cut diamond, D colour, VVS1 clarity, with a weight of 2.36 carats, in an open back claw setting, flanked by two tapered baguette cut diamonds in open back rubover settings with a combined approximate weight of 0.45 carats. The total approximate diamond weight is 2.81 carats, to an impressive flanked solitaire design featuring curving corner claws, a linear pierced gallery and angular open backholing, leading to raised shoulders and flowing through to a solid D-shape shank. Tested platinum, circa 1950, accompanied by Gemological Institute of America (GIA) report #2225798012. Diamonds are classified by scientists into two main types, depending on the presence of nitrogen in the diamond's chemical makeup. Type II diamonds contain little to no such impurities. This type is further subdivided into two groups, ‘a’ and ‘b’, both of which make up less than two percent of all gem quality diamonds. Type IIa diamonds are extremely rare, and the most pure of all diamonds, and consequently exhibit superior transparency. This type was first identified as coming out of India, namely the Golconda region. Some of the most famous diamonds in the world...Category
