What Are Trillion Cut Diamonds? History and Overview
Trillion cut, trilliant, or Trillian best describes a triangular cut of a gemstone. Having said that, a trillion cut diamond is one that is cut into a triangular shape. Like a typical triangle, this cut has three sides of equal length and a flat table as the surface.
The relatively contemporary diamond shape was developed during and after World War II. However, it was only in 1962 when the Henry Meyer Diamond Company had it patented. When the patent expired, the cutting method became freely available for the use of diamond cutters worldwide.
The global use of the trillion cut led to diverse variations of this technique. It became dependent on how a cutter chooses to fashion the stone. With different companies making modifications to the original cutting method, a mass of branded names was established for marketing purposes.
History shows us a lot of other locations where triangular brilliant-cut stones originated. Like those that came from Amsterdam in the 18th century. Yet, irrespective of where we want to draw the point of inception for trillion cut diamonds, the modern ones had their official beginning in New York, 1962.
Trillion Cut For Better Yield?
GIA (Gemological Institute of America) considered the trillion cuts as adventurous and provocative. In the present day, the terms triangular brilliant or triangular modified-brilliant are how they describe unbranded triangle-shaped diamonds.
Trillion cut diamonds usually have shallow depths. For the most part, this shallow thorough is due to the nature of the rough being used. Triangular shaped roughs called macles are typically utilized in shaping trillion cut diamonds. This process is done to boost carat weight retention.
The above example shows that the macle’s overall shape and outline render it a perfect prospect to achieve a triangle-shaped and cut polished diamond.
Granting there are different variations; trillion cut diamonds have rounded corners with faintly curved sides of equal length. The patented design was straight and pointed instead of curved. This variation may be due to the flattened, vaguely triangular shaped macles they’re cut from.
Trillion Cut – The Basics
Trillion Cut diamonds possess unique features such as:
- Triangular shape
- Great fire
- Sharp brilliance
Its three equal sides comprise about 31 or 50 facets depending on how the diamond will be used – as solitaires or accent stones. For solitaires, it employs curved or convex cut, unlike accent stones that are uncurved or concave.
Different variations of trillion cuts include round-cornered triangular, modified shield cuts, and triangular step cuts. Its distinctive style creates a great fire and gives off sharp brilliance, most especially when cut to the perfect depth.
The difference of cuts and shapes of trillion cut diamonds depends on what they are intended to be used as – center or accent. But, as most diamonds are derived from the brilliant, they do an excellent job of hiding inclusions. They can be an undoubtedly stunning center stone when cut to a high standard.
Trillion cuts intended as a center diamond in a solitaire ring is cut with typically 50 facets. They are also set to have a light cure or convex shape to make the most of the diamond’s perceived size.
On the other hand, if it is for an accent diamond, like an engagement ring, it will be cut with 31 facets and won’t feature convex edges. Still, with its long sides, it will appear larger than its actual carat weight.
Cutting A Trillion
No other diamond is trickier to cut than the trillion cut diamond. Cutting one requires a lot of precision and detail as it is effortless to chip a trillion cut stone both while cutting or polishing and setting it as a piece of jewelry.
Every piece should be cut with the exact idea of how it will be used in a piece of jewelry since different uses of the trillion cut recommend a precise shape. They are supposed to be shallower than other stones, but it is essential not to make them too shallow or lose a considerable amount of their brilliance and fire.
The complication of a trillion cut diamond’s cutting process is one reason it was rarely attempted before the 20th century. However, with the laser drill’s invention, it no longer requires a diamond to be rough and with a precise shape and parameters to achieve the ideal trilliant.
Recommended Proportions for Trillion Cut Diamonds
The symmetry, polishing, and proportions of a trillion cut diamond extensively impact its visual appearance than other fancy cut diamond shapes. Thus, a minimum of “very good” ratings for both polish and symmetry is recommended.
|Table %||56% – 66%||54% – 68%||52% – 70%||Outside Ranges|
|Depth %||35% – 46%||34% – 48%||33% – 52%||Outside Ranges|
|Polish / Symmetry||Excellent – Very Good||Excellent – Very Good||Good||Outside Ranges|
|Length to Width||1||0.95 – 1.05||1.10 – 1.20||Outside Ranges|
|Girdle Thickness||Very Thin – Slightly Thick||Very Thin – Slightly Thick||Very Thin – Thick||Outside Ranges|
|Culet Size||None||Very Small||Small||Outside Ranges|
Length to Width Ratios
The best-looking state of a trillion cut diamond is when it forms an equilateral triangle. Thus, length to width ratios should be paid extra attention to when looking at a trillion cut diamond. If at all possible, 1:1 :1 proportion on each side is the best. Irregular or out of symmetry diamonds are noticeable and should be avoided.
Buying Guide for Trillion Cut Diamond
There is not much to obsess over the four Cs when buying a ring that features a trillion cut diamond access. You only need to make sure it matches the center diamond by picking one with similar clarity and color grades.
The best choice is usually a three-stone ring with a trillion diamond accent. It offers a trillion cut diamond’s modern appearance but with a better selection of center diamonds for you to choose from.
A loose trillion cut diamond is another thing. If you want one as a center stone, then there is a list of things you need to consider.
As mentioned above, trillion cut diamonds are, in many cases, cut shallow. This cut is to help achieve an illusion of a larger diamond since more of the diamond’s weight is dispersed horizontally than vertically.
Be careful about the depth, though. An overly shallow cut may affect the trilliant’s brilliance and fire. This aspect may result in a less exciting appearance, even with the illusion of a larger size. Thus, a very shallow cut is best avoided.
The best thing about a trillion cut diamond is how it conceals inclusions and blemishes well. This characteristic keeps you from overpaying for a diamond with a flawless clarity grade.
There is no need to pay extra for a diamond with “colorless” D, E, or F color grade like clarity. Instead, it would be best to choose one that looks colorless in its setting.
Trillion Cut Diamonds’ Pros and Cons
Like any diamond shape and cut, each one has its benefits and downsides. What’s important is that you should get the diamond shape that matches best with your style.
- It offers exceptional brilliance, especially when it isn’t cut too shallow
- It makes the diamond appear more extensive than a similarly-sized round or princess-cut, thus letting you make the most of the diamond’s carat size
- It presents a unique option to the traditional cuts that most people use as centerpiece diamonds
- It is more vulnerable to chipping due to its points. Thus an excellent protective setting should be used
- It may be more challenging to set and may need uncommon settings that can house that shape
- Trillion cut diamonds tend not to work well with some prongs designs. They work best with V-prongs since they can wrap the stone and protect them.
- It requires more maintenance than other cuts. Regular cleaning and care help maintain the brilliance since its shallow cut causes it to be dimmed easily, even with just a bit of dirt.
Creative Uses and Orientations of Trillion Cut Diamonds
Trillion cut diamonds can be used in two main designs for rings. They are typically presented as a single diamond in a solitaire setting or as accent stones in three-stone settings. The solitaire setting is when a ring has a single mounted stone while three-stone, as the name suggests, has three mounted stones.
It differs mainly on the orientation of the stone, and both have their advantages. Trillion cut stone’s single line of symmetry has one side of the diamond ideally placed upright and vertical to the wearer’s finger.
Another trendy setting of a trillion cut diamond places its perpendicular side closer to the wearer’s hand and its apex near the fingernails. This positioning lets the stone flatter the finger’s length and makes the wearer’s hand look more feminine.
If installed the other way – with the perpendicular side of the triangle near the nail, the appearance conveys a slightly robust façade. Thus, making it a more comfortable choice for rings, particularly those designed for men.
Trillion cut diamonds can be used for earrings too. In their case, the orientation is less significant since they won’t be permanently held when worn. An irregular or eccentric triangular shape gives the jewelry a playful touch to it.
There seems to be no limit to trillion cut diamond uses. Another example is a pendant for a necklace with the apex pointing upwards. Like earrings, the orientation is not entirely relevant. It can have the highpoint drawn down or up.
Where to Buy Trillion Cut Diamonds
The emerging popularity of trillion cut diamonds no longer limit their availability from custom jewelers only. Reputable online stores like James Allen or Leibish & Co have a limited selection of different jewelry pieces with trillion cut diamonds.
