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.

Cufflinks rose to popularity during the 1800s as fashionable men sought a refined and elegant solution for keeping their shirtsleeves together. Prior to this accessory, which initially materialized as a simple chain fastened to a button, men were lacing the ends of their sleeves with ribbon or string. Today, there are all manner of antique and vintage cufflinks that add flair and functionality to relaxed casual wear as much as they do for classy formal attire.

It wasn’t long before diamonds, emeralds and other precious gemstones began to appear on cufflinks, a means of adding ornament to clean and starched formal wear. When clothing manufacturers began to produce shirt cuffs and collars with more durable materials during the 19th century, a class of newer, stronger cufflinks gained credibility as being both essential and stylish. In the decades following this era’s design evolution, an entire industry bloomed around the craft of these subtle statement pieces.

Luxury brands more often associated with engagement rings and bracelets, such as Cartier and Tiffany & Co., have added cufflinks to their lines over the years, and jewelry designers, working in numerous styles, have explored the use of different materials and integrated a variety of ornamentation. Understated cufflinks of gold and platinum are guaranteed to cleanly complement any ensemble, while more niche designs allow the jewels to truly shine.

Cufflinks are practical pieces of jewelry that can also be very expressive. Consider the event for which you’re donning cufflinks and accessorize accordingly, but know that a distinctive pair of cufflinks, such as the colorful confections offered by Trianon, can pop against your dressy evening wear. Whether they’re geometric wonders of the Art Deco era, reliably relevant skull jewels or glittering accessories designed by Van Cleef & Arpels, adorned with the maison’s celebrated four-leaf clover or prominent animal motifs, you can delicately break from what can be a stuffy business meeting by introducing personality and pizzazz with a duo of nifty cufflinks.

A carefully chosen set of cufflinks can bring a stylish outfit together — literally. Find a large, luxurious collection of contemporary cufflinks as well as irresistible vintage pieces on 1stDibs today.
