Antique Diamonds

The question most frequently asked of our jewelry experts at Lang is “what is the difference between antique cut and contemporary cut diamonds?” The answer is to be found primarily in the fascinating historical and technological evolution that has taken place at the cutting wheel. For centuries diamond cutters have applied different approaches and techniques, by hand, to the ancient rough crystals that come from the earth. Most of the Lang collection dates from the late 19th century to the middle of the 20th century, a period of time that beautifully encapsulates a range of artful and inventive techniques used to bring out the best in each unique diamond crystal. Unlike contemporary diamond cutting, which primarily uses machines and endeavors to create a reliably identical product on a mass-produced scale, the diamonds of the past differ from those of the present and also from one another. Their captivating subtleties, coupled with their increasing rarity, make their unique charms highly desirable and sought after.

Rose Cut Diamonds

One of the oldest cuts represented in our inventory is the ravishing rose, emerged in the 1500s and named for its resemblance to the flower. This romantic cut—with a flat bottom, domed top, and as many as 24 facets—was developed in harmony with the shape of rough diamonds and popularized in the Georgian Era. Candlelight filled the homes of 18th-century jewelry collectors with the perfect glow to showcase these delightful stones.

While they enjoyed a brief resurgence in the Victorian Era, it is only recently that the sparking rose cut has once again caught the eye of contemporary wearers. Though we more often see these beauties set as glittering side stones to enhance the center of another cut, we’re always excited when we do find a ring with a sizeable rose cut stunner!

Mine Cut Diamonds

Dating from 18th century Europe, the mine cut, also known as the antique cushion cut, is the precursor to the modern round brilliant cut. But it isn’t actually round at all! The edges form a soft square or “cushion” shape, resulting in stones that are especially lovely when viewed under the candlelit conditions typical of the 18th to mid-19th centuries, before electricity. Similar in this way to the rose cut, mine-cut diamonds, though lesser known today, also enjoys a devoted following among antique jewelry lovers.

European Cut Diamonds

The late 1800s saw a boom of technical innovation in diamond cutting and fine jewelry making alike. Though older round cuts had existed for some time, the classically beautiful old European cut emerged in the latter half of the 19th-century and remained a finger-dazzling favorite through the first half of the 20th. Around the mid-century, they gave way in popularity to the round brilliant cut, and they have characteristics both of this and the older mine cut.

European-cut diamonds are well represented in our inventory since so many of our original antique and vintage engagement rings date from this period. Many of the rings in our Lang Engagement Collection feature original old European cut stones in vintage-inspired settings as well. When you fall in love with the subtle radiance and warmth of the stone at the center of a Victorian, Edwardian, or Art Deco engagement ring, it’s very likely to be one of these cuts.

Modern Round Brilliant Cut Diamonds

The modern round brilliant cut has become nearly synonymous with the idea of a diamond. Developed in the early 20th century but not widely used in jewelry until the 1940s, today it’s the most popular diamond cut. And we aren’t surprised! The combination of brilliance (hence the name) and fire seen in the standard round brilliant represents the height of the diamond cutter’s art. Though our inventory tends to favor the old European cuts of the Edwardian and Art Deco eras, we enjoy mixing in a good selection of these slightly more modern sparklers, which you’ll find among our Retro, Mid-Century, Vintage, and Estate pieces. The brilliant cut is the perfect option for those seeking maximum fire in a vintage or vintage-inspired package.

Fancy Shaped Diamonds

“Fancy” simply refers to any brilliant-cut diamond that isn’t round. These variations have a long history and include many shapes popular as alternative center stones in striking engagement rings: emerald, Asscher, marquise, pear, oval, and “moval”—a hybrid of the marquise and oval shape, to name a few. These stones speak directly to the personality of those who choose them, and tend to result in a “that’s the one!” moment we like to think of as love at first sight.

The sophisticated simplicity and tailored lines of the emerald cut, originally intended for the green stone of its namesake, has become increasingly popular for diamond engagement rings. The variety of proportions found in this rectangular step cut gives each stone a character as distinctive as the wearer. Combined with clean geometric facets, the emerald-cut diamond is truly a stone for idealists!

As we learned back in elementary school, every square is a rectangle, but not every rectangle is a square! Enter the Asscher, that infinity pool of facets that draws the eye and inevitably leads to the question, what kind of diamond is that…? Technically recognized by the GIA as the “square emerald cut,” it gets its popular name from Dutch diamond cutter Joseph Asscher, who developed the cut in 1902. If you love the clean lines of an emerald cut with the symmetry of a round brilliant, this is the one for you.

Of course, there’s quite a bit more fascinating detail to the long history of diamond cuts and the way we’ve used diamonds in jewelry—dating all the way back to the Romans, if not further!
