Summary

Transitional cut diamonds bridge the gap between old European cuts and modern brilliants, offering vintage charm with improved sparkle.

  • Developed in the 1870s by Henry Morse, focusing on beauty over carat retention.
  • Features include a smaller table, higher crown, and larger culet than modern cuts.
  • Often found in vintage rings, prized for their unique blend of old and new styles

 

“We’re going through a bit of a transition period right now.”

Sure, we all understand what this means when it pertains to a restaurant remodel, a big relationship change or a career shift, but what does it mean when referring to a diamond cut? What is a transitional cut diamond? Read on to learn what a transitional cut diamond is, its key characteristics, its history and why it might be the perfect gemstone for you.


What is a transitional cut diamond?


A transitional cut diamond is a unique blend of vintage and modern styles, encompassing the various diamond types that arose between the Old European and the round brilliant cut. As technology advanced, diamond cutters began experimenting with new cuts by adding facets, improving symmetry and refining angles. The goal of changing how diamonds were cut was to continue improving their appearance—specifically their sparkle. Adding facets helped. However, it would take a while before diamond cutters achieved the sparkle of the round brilliant cut diamond. But, along the way, these efforts resulted in a series of diamond cuts with more sparkle than previous cuts. These diamonds, which were primarily created in the 1930s and 1940s, are known as transitional cuts.


Key characteristics of transitional cut diamonds


Because transitional cut diamonds essentially bridge that gap between the Old European diamond cuts of the late 1800s and early 1900s and the round brilliant cuts of today, the key characteristics of transitional cut diamonds tend to be a blend of both. Let’s look at a few:

  • Chunky, defined features. Transitional cut diamonds have a more substantial, rounded shape compared to modern round brilliants, with slightly larger facets and a thicker girdle (the widest part of the diamond, which helps with durability and stability). These features contribute to the diamond's "chunkier" appearance, giving it a distinctly vintage look.
  • Handcrafted charm with enhanced precision. Transitional cut diamonds blend the handcrafted charm of Old European cuts with the benefits of modern technology. While they maintain a traditional look, they offer improved symmetry, clarity and light performance, thanks to advancements in cutting machinery. This results in a more polished, refined appearance compared to older cuts.
  • Soft, warm glow. Transitional cut diamonds emit a softer, warmer glow compared to the intense sparkle of modern round brilliants. Their larger, fewer facets contribute to a more subtle, elegant shimmer, making them perfect for those looking for a classic, understated look.


History of the transitional cut diamond


The transitional cut diamond emerged during a pivotal time in diamond cutting history, bridging the gap between the Old European cut and the modern round brilliant cut, which spanned the 1930s and 1940s. During this time, the diamond industry was influenced by the rise of modern machinery, which allowed for more accurate faceting and cutting. While these diamonds were crafted by hand, advancements in machinery allowed for improved symmetry and precision, which had previously been difficult to achieve with older methods. These diamond shapes were designed to have more brilliance than the Old European cut, with a more refined shape and larger facets, but not yet achieving the flawless precision and sparkle of today’s round brilliants.
As the round brilliant cut began to dominate in the 1950s, the transitional cut represented an important step in the evolution of diamond cuts. It combined elements of the old European cut with the emerging brilliance of modern diamonds, offering a unique aesthetic. Today, these diamonds are cherished for their historical significance and distinctive appearance.


Why choose a transitional cut diamond engagement ring?


When it comes to selecting the perfect engagement ring, the diamond cut plays a crucial role in both the aesthetic and the overall feel of the piece. A transitional cut diamond engagement ring offers a unique blend of vintage charm and modern refinement. Here are some reasons why a transitional cut diamond might be the perfect choice for your engagement ring.


Vintage appeal, modern twist 


For those who appreciate the beauty of vintage diamonds but prefer the look of a more refined, modern cut, transitional cut diamonds offer the perfect balance. This cut is ideal for buyers who want something unique and timeless without fully committing to an antique or old cut style.


Pretty pricing 


Transitional cut diamonds are often priced more affordably than modern cuts because they typically have a smidge less sparkle and brilliance due to their unique faceting styles. This can make transitional cuts a more budget-friendly option for buyers looking for a unique, vintage-inspired look without the premium price tag of contemporary cuts.


Distinctive and unique 


Transitional cut diamonds are far less common than modern round brilliants, making them an excellent choice for someone who wants a more unique diamond. Their distinct appearance— slightly less brilliant but still dazzling—sets them apart from other popular diamond cuts, perfect for those who want to stand out. And, people likely aren’t as familiar with transitional cut diamonds, giving you a fun little factoid to share!


Historical significance 


Transitional cut diamonds hold a special place in the history of diamond cutting. They were a stepping stone between the old and new, representing a period of transition and innovation in diamond craftsmanship. For some couples, choosing a transitional cut can be symbolic of their own journey, bridging the past and future, combining tradition with progress. These diamonds carry with them a rich heritage, offering not only a beautiful piece of jewelry but also a meaningful symbol of growth, change and the passage of time in a relationship.


How to care for your transitional cut diamond


Regular cleaning is vital to ensure your transitional cut diamond continues to shine for years. These diamonds have slightly broader facets, so dirt and oil can accumulate more easily. Use a gentle, non-abrasive cleaner and a soft brush to remove debris from all parts of your ring. Because transitional cuts may have thicker girdles, check for any looseness in the setting during regular jewelry checkups. Lastly, proper storage is key. Keep your ring in a cloth pouch or separate compartment to help keep it from scratching other jewelry.


Cons of transitional cut diamonds


While there’s a lot to love about transitional cut diamonds, there are some aspects that some may see as drawbacks. Here are a few potential cons of transitional cut diamonds.

  • Less sparkle and brilliance. Compared to modern cuts like the round brilliant, transitional cut diamonds have fewer facets, which results in less brilliance and sparkle. This can be a drawback for those who prefer the intense shine of contemporary cuts.
  • Not as symmetrical or precise. While these cuts improved upon the symmetry and precision of older cuts, transitional cut diamonds don’t have the same level of symmetry and precision as round brilliants, which can make them less visually “perfect” in some cases.
  • Limited availability. Transitional cut diamonds are less common than more modern cuts, making finding the exact size or shape you want a bit more challenging. They may also be harder to find in specific settings or ring styles.
  • Potential for lower clarity. As always, you’ll want to consider the 4Cs when selecting a diamond. In the case of transitional cut diamonds, pay extra attention to clarity. The broader facets and thicker girdle of a transitional cut diamond can sometimes make inclusions more visible, particularly in diamonds with lower clarity grades. 
  • Higher maintenance needs. Due to the thicker girdle and chunkier facets, transitional cut diamonds may require more care when setting in a ring to ensure they remain secure and are not damaged. They may also attract dirt more easily than round brilliant cut diamonds, requiring more frequent cleaning.

     

Transitional cut diamond vs other diamond cuts


Sometimes it’s easier to compare diamond cuts head-to-head to see where they have similarities and what sets them apart. Here are a few comparisons between transitional cut diamonds and other similar diamond cuts.


Transitional cut diamond vs brilliant cut 

  • Similarities: Both the transitional cut and the modern round brilliant cut aim to maximize sparkle by using faceting to reflect light. Both cuts are round, as the transitional cut was a precursor to the round brilliant.
  • Differences: The round brilliant cut features more facets (typically 58) and greater precision, resulting in more sparkle and brilliance than the transitional cut. The transitional cut, with fewer facets and a thicker girdle, has a chunkier, vintage appearance that gives it a softer, warmer glow. It offers less brilliance but, some may argue, more character.

 

Transitional cut diamond vs Old European 

  • Similarities: Both cuts have similar faceting patterns, and both are known for their vintage charm. They both emphasize a more rounded, soft shape and are typically handcrafted.
  • Differences: The key difference is in the symmetry and precision. The Old European cut has a more pronounced culet (the flat bottom of the diamond), and the transitional cut features better symmetry and more precise angles. The transitional cut has larger facets and a thicker girdle, offering a more polished look. In contrast, the Old European cut tends to be a bit more "chunky" and less refined.

 

Transitional cut diamond engagement ring - why it’s unique


A transitional cut diamond in an engagement ring is perfect for someone who loves vintage style but also wants the benefits of modern cutting techniques. It combines the charm of antique diamonds with better clarity and precision. Its affordability and distinct appearance make it an excellent option for those seeking a larger carat size without the high price of modern round brilliants. Plus, the unique look of a transitional cut diamond adds a historical feel to any engagement ring.


Where to buy transitional cut diamonds


Finding a transitional cut diamond may require more effort than more common cuts. Still, there are several reputable sources where you can find these unique gemstones. Established jewelers specializing in antique or vintage jewelry online and in physical stores are a great place to start. 


For those who prefer a more traditional buying experience, visiting local independent jewelers can also be a good option. Many jewelers specializing in antique and estate pieces will carry transitional cut diamonds or may be able to source one for you. Regardless of where you’re shopping and buying, you may want to ensure your diamond comes with a gemstone certification from a reputable gemological institute to ensure the diamond’s quality and authenticity.
