Trilliant cut

A bit of history on the trilliant cut diamond:

Triangle, Trilliant and Trillion are all permutations of a name applied to a triangular brilliant cut diamond. The Trilliant and Trillion cut was introduced by the Asscher brothers in Amsterdam and was later trademarked by the Henry Meyer Diamond Company of New York in 1962. Now that the patent has expired, the term “Trilliant Cut” is used to refer to all triangular shaped gems, even step cut and cabochon stones. 

Their creation is still trademarked; however, all triangular cuts tend to be referred to as Trillion cuts in our modern times.

The Trillion cut is a triangular shape comprised of three ideally equal sides and 31, 44 or 50 facets, and their shape follows a naturally occurring crystalline formation on diamonds, known as Trigons. The amount of facets used depends on whether the diamonds are used as solitaires or accent stones.  Accent triangles would typically be smaller with less facets.

Triangular crystals of rough diamonds, known as Macles, usually form the source of a Trilliant or Trillion cut diamond. The basic shape is already there. With precision cutting and faceting, this becomes the Trilliant or Trillion cut diamond.

For solitaires, a curved or convex cut is ideal. For accent stones the cut could be straight or concave. Additional variations include round-cornered triangular, modified shield cuts and triangular step cuts. The trillion’s unique style has great fire and displays sharp brilliance if the stone is cut to the correct depth.

Trillion cut diamonds are most often used as side stones to compliment larger solitaire stones in engagement rings, although they also make for a perfect solitaire stone themselves considering their unparalleled brilliance and fire.

Size matters!

Compared to a standard round brilliant cut of the same carat, a Trillion cut diamond will usually appear larger. The reason for this is that the Trillion cut diamonds are cut shallow, which makes the total diamond surface bigger in the same carat than a round brilliant cut diamond. This also rings true of the oval cut.

Although Trilliants are always cut shallower than other diamonds, such as the cushion cut, take care not to purchase a stone that is cut too shallow, as the light then partially passes through the diamond and it will lose some of its brilliance.

If size matters to you as individual, you should consider a Trillion cut diamond. The Trillion cut boasts a unique triangular shape that not only looks stunning but also has the benefit of hiding inclusions well. This affords you the opportunity to purchase a larger stone with eye clean inclusion whilst compromising a bit on colour due to the significant brilliance of the cut.  If your choice falls on a Trilliant, chances are that you might never see someone else with a similar design.  This is undoubtedly an individualistic and rare choice.

What to look for when buying a trilliant cut Diamond.

The Trillion cut is a unique, brilliant, and beautiful cut that definitely deserves more attention in our opinion.  It might however not always be available immediately.

The dominance of round and princess cuts, as well as the cushion, emerald, pear, asscher, oval, and the other more popular cuts, unfortunately, means that the trillion cut is usually relegated to a side stone in most situations.

However, if unique jewellery and setting designs can work well with a triangular-shaped brilliant cut diamond, we would definitely recommend considering a Trillion cut.

The Trillion cut is a great choice for commissioning a piece of jewellery that’s a little bit different, and you’re not just limited to rings.  A Trilliant cut is also an ideal choice for a pendant or earrings when you manage to find a matching pair.

The unusual shape of a Trillion ring also makes it a great choice if you like stacking rings. A perfect gift for special anniversaries, stacking rings can be made to fit around a trillion stone and create a unique look.

If exceptional purity in a diamond s a requirement, you will probably prefer another cut.  Mackle or Trigon rough diamonds, from which Trilliants are polished, seldom have exceptional purities.  A Mackle rough diamond usually consists of two separate diamonds that were “welded” together by nature over millions of years, and small particles or inclusions are usually faintly visible between the two “welded” stones on the edges.  They are often completely eye clean, but not in the VVS or VS range of purity.
