How Unique & Rare Are Trillion Cut Diamonds?

Trilliant, Trielle, and Trillian Cut diamonds are other names for Trillion cut diamonds.

This is a brand-new diamond cut created in the 1960s. As the title indicates, this cut produces a triangular-shaped diamond with three equal sides, a level table on the surface, and flat or sharp edges. Trillion cut diamond rings are exceptionally rare. Trillion cut diamonds, compared to other diamond shapes, are more fitted to being used as accent stones within a jewelry creation than as a center gemstone. However, with the proper cut, carat weight, and color grades, they may be used as a solitaire too. The Trillion cut diamond complements current jewelry designs well, and this diamond cut is a fantastic choice for those looking for an on-trend streamlined style that stands out from the crowd.

A Brief History of Trillion Cut Diamonds 

In contrast to other cuts, Trillion cut diamonds have a relatively new history. The Asscher siblings from Amsterdam invented the first triangular cut in the 18th century. Their aesthetic impacted the briolette and Old Mine triangular diamond cuts, which in turn influenced Leon Finker, who invented the Trillion cut in the mid-1960s.


In the late 1970s, Finker sought to establish the term "Trillion" as a trademark, but by then, any diamond with a triangle cut had already been given that term. After patenting the cut in 1978, he trademarked the term "trielle" in 1991. All diamonds with a triangular cut are now known as Trillion cuts. The terms "triangular brilliant" and "triangular modified brilliant" are used to describe non-branded triangular cuts.

Benefits and Drawbacks of Trillion Cut Diamonds

There are benefits and drawbacks to Trillion cut diamonds because of their odd form. It's crucial to take into account each of these factors while determining whether this cut is the best pick for you. They seem larger than round or princess cut diamonds of the same carat size. Because of their incredible brilliance and fire, they can mask imperfections and color. When unmounted or improperly perched in its place, Trillion cut diamonds' pointed edges are vulnerable to chipping.

Secure prongs are necessary as they safeguard the diamonds' edges, and the V-prong works best for doing so. You'll need to clean your diamond more regularly than you would the other shapes, as Trillion cut diamonds have a shallow cut that makes them readily dulled by trace quantities of dirt or dust. There may be subtle variations among Trillion cut diamonds, but they always have a triangular form with three sides that are typically of the same length. The sides might be straight for a very graphic appearance or slightly rounded for a softer and bigger appearance.

A center Trillion-cut diamond in an engagement ring is rare, although many designers use them as accent stones. The lovely shine added by the Trillion cut diamond rings and the tapered edges go well with most appearances. Trillion shaped diamonds when used as accents  contrast well with square or rectangular shape center diamonds . Furthermore, when set in yellow gold, the triangular diamond  shapes appear even more beautiful.

When compared to a diamond with a deeper cut, a Trillion cut diamond appears larger from above because it often has a moderate to shallow cut. Since the lengthy sides may give it the appearance of being larger than it actually is, a Trillion cut diamond ring is perfect for people who desire a big look on a tight budget. Since it's hard to find and to get your hands on a Trillion cut diamond ring, you are sure to stand out from the crowd. The geometric pattern works well with a variety of settings, including bezels, halos, and solitaires. At Friendly Diamonds, you are sure to make a great choice for your Trillion cut diamond needs.
