Trillion Cut Diamonds – Triangular Cut Diamonds

Trillion shape diamond

Triangular Brilliants, also known as Trillions and Trilliants, are mixed cuts with three equally straight or slightly curved sides. They are typically shallow and are often cut from flattened, triangular rough called macles. Triangular Brilliants are often seen as side stones for other fancy shapes, but when well proportioned, one can also be a stunning centerpiece in an engagement ring. The Trilliant, which was once a trademarked cut developed by the Henry Meyer Diamond Company, comes to three very sharp points while other Triangular Brilliants may have  softer and slightly rounded points. When cut to certain proportions, Triangular Brilliants are very bright and lively stones. The optimal length to width ratio for Triangular cuts is 1:1.

Special Characteristics of Triangular Cut Diamonds

Triangular Brilliants are often found with shallow total depth percentages.? This is common, as they may originate from very flat rough.? If the points are sharp rather than rounded, they should be protected by prongs or a bezel.?

Size Matters

Triangular Brilliants may look large from the ?face up? position for their relative carat weights, because they are often unusually shallow.? This is to be determined on a stone by stone basis, though, as some Trillions are cut to greater depth percentages.? A shallow Trillion will most often face up quite large, but note that excessively shallow stones may loose brilliance if they get a little dirty.? One challenge of owning a shallow Trillion is keeping it clean for maximum sparkle.

Basic Triangular Brilliant Cut Guidelines

Curved or straight sides are a matter of personal preference, but sides should be equal and even.? Look for symmetrical stones that have a pleasing triangular shape.? Triangular Brilliants run the gamut when it comes to proportions, so they are best judged by the eye, or at the very least–if buying online, by photographs and/or an experienced ?vendor eye.?
