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 rings, vintage engagement rings or Art Deco engagement rings.

Vintage three-stone rings are pieces of jewelry adorned with three individual gemstones.
In 2001, De Beers launched the “Past, Present and Future” ring with a trio of diamonds and helped establish the three-stone ring as a staple jewelry piece. When it comes to modern engagement rings, many couples on the search for the perfect ring choose three-stone rings for their appeal and symbolism. When the Duchess of Sussex’s three-stone engagement ring was unveiled, it instantly piqued the interest of ring buyers and future fiancées.
Some popular gemstone cuts for three-stone rings include emerald, square and round. Three-stone rings can feature gemstones that are all the same type or a mix that varies in color, size and type. The three main size styles for these gemstones are graduated, slightly graduated and equal. Each of these styles differs in its carat weight. The rings can also be made from various metals such gold, silver, yellow gold or platinum.
Three-stone rings frequently have a slightly curved silhouette that makes them a great pairing for wedding bands or a foundation for a stacked design. You can add other rings such as an eternity band (an ideal choice for a wedding or milestone anniversary), a versatile band ring or a solitaire to contrast minimal pieces with more ornate statements.
The three-stone ring is an iconic accessory that will endure through time. Browse an assorted collection of vintage three-stone rings on 1stDibs, each featuring different gems and wedding-band styles.
Ancient Egyptians referred to the vibrant stone as the “gem of the sun.”
