Antique Split Shank Engagement Rings

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.

Rings have been symbols of devotion since the days of Ancient Greece, a practice later adopted by the Romans for marriage ceremonies. Bridal rings were given an official meaning by Pope Nicholas I in the year 850 as proving a man’s intent to marry his bride-to-be. Antique sapphire and diamond bridal rings continue to hold meaning for many couples today.

Precious stones sometimes adorned these early engagement rings and bridal rings, which were usually gold bands. Diamond engagement rings and diamond bridal ring sets weren’t the dominant choices until 1947 when De Beers popularized them with their “A diamond is forever” marketing campaign.

Recent trends in jewelry design have seen the rise of diverse gems and metals in bridal rings. Rubies, sapphires and other colorful precious gems have quickly gained favor with brides who want a unique and vibrant bridal ring.

Modern bridal ring styles can be breathtaking and break traditional trends, while vintage engagement rings harken back to this rich heritage of design. Featured on 1stDibs is a stunning array of bridal rings from world-famous jewelers including Tiffany & Co., Roman Malakov and Antinori Fine Jewels.
