Antinori Fine Jewels for sale on 1stDibs

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.

Explore a range of rings, earrings, necklaces and other jewelry created by Antinori Fine Jewels on 1stDibs.

The Legacy of Diamond in Jewelry Design

Antique diamond rings, diamond tiaras and dazzling vintage diamond earrings are on the wish lists of every lover of fine jewelry. And diamonds and diamond jewelry are primarily associated with storybook engagements and red-carpet grand entrances — indeed, this ultra-cherished gemstone has a dramatic history on its hands.

From “A Diamond Is Forever” to “Diamonds Are a Girl’s Best Friend,” pop culture has ingrained in our minds that diamonds are the most desired, the most lasting and the most valuable gemstone. But what makes the diamond so special? Each stone — whether it’s rubies, sapphires or another stone — is unique and important in its own right. April babies might claim diamonds for themselves, but just about everyone wants this kind of sparkle in their lives!

There are several factors that set diamonds apart from other stones, and these points are important to our gem education.

Diamonds are minerals. They are made up of almost entirely of carbon (carbon comprises 99.95 percent; the remainder consists of various trace elements). Diamonds are the hardest gemstones, ranking number 10 on the Mohs Hardness Scale. Even its name, diamond, is rooted in the Greek adamas, or unconquerable. The only object that can scratch a diamond is another diamond. Diamonds are formed deep within the earth at very high temperatures (1,652–2,372 degrees Fahrenheit at depths between 90 and 120 miles beneath the earth’s surface) and are carried up by volcanic activity. Diamonds are quite rare, according to the Gemological Institute of America, and only 30 percent of all the diamonds mined in the world are gem quality.

In the 1950s, the Gemological Institute of America developed the 4Cs grading system to classify diamonds: clarity, color, cut and carat weight. Not all diamonds are created equal (there are diamonds, and then there are diamonds). The value of the diamond depends on the clarity (flawless diamonds are very rare but a diamond's value decreases if there are many blemishes or inclusions), color (the less color the higher the grade), cut (how the diamond’s facets catch the light, certain cuts of diamonds show off the stone better than others) and carat weight (the bigger, the better).

When you start shopping for a diamond engagement ring, always prioritize the cut, which plays the largest role in the diamond's beauty (taking the time to clean your diamond ring at least every six months or so plays a role in maintaining said beauty). And on 1stDibs, a range of buying guides can be found for those in the market for antique engagement ringsvintage engagement rings or Art Deco engagement rings
