trillion cut diamonds explained

While trillion-cut diamonds are not often set as the centre stone in an engagement ring, they can exhibit breathtaking beauty when placed as diamond accents within a three-stone diamond ring.

The term is a fusion of “triangle” and “brilliant.” This fantastic and unique diamond cut is an excellent option for those seeking an unconventional shape without compromising on the dazzling radiance.

Jewellery designers often incorporate trillion-cut diamonds across many pieces, ranging from engagement rings to bracelets, necklaces, and stud earrings, ensuring you discover the ideal addition to your collection.

Given that trillion-cut diamonds are often used as accent stones, the emphasis on cut, clarity, and colour is comparatively less vital than it would be for a centre diamond. In most cases, it is recommended to prioritize diamonds with an “eye-clean” appearance and colourlessness in correlation to their setting.

What Is a Trillion-Cut Diamond?

A trillion-cut diamond, also known as a trilliant cut, is a diamond that has been fashioned into a triangular shape. Typically, a trillion-cut diamond possesses three sides of equal length, forming a triangular silhouette, while its surface showcases a flat table.

The inception of the trillion cuts is relatively recent, dating back to the 1960s. Defined by the GIA as an “adventurous and provocative cut,” the trillion cut boasts a contemporary and captivating appearance that can lend itself to some striking and unique engagement rings and custom jewelry designs.

Unlike most diamond shapes, such as rounds and ovals, the trillion cuts are more prevalent for accentuating side-stone diamonds rather than serving as a centrepiece. This can often be seen in many popular three-stone engagement rings trending on social media.

Despite the trend of employing trillion-cut diamonds as side stones in engagement rings, some unique engagement rings make the trillion cut the focal point of the design.

The Basics of Trillion-Cut Diamonds

The trillion-cut diamond boasts a distinctive triangular shape with three sides of equal length. Like the round brilliant cut, a trillion-cut diamond features a flat table on its surface. This particular cut is renowned for its captivating modern aesthetic.

Due to its elongated sides, a trillion-cut diamond frequently gives the illusion of being larger than its actual carat weight.

Interestingly, the term “trillion cut” as we recognize it today, was trademarked by the Henry Meyer Diamond Company of New York in the 1960s, initially referred to as the “trilliant” cut. However, early instances of trillion-cut diamonds were believed to be fashioned in Amsterdam as far back as the 19th century.

Many adaptations of the trillion cut have been crafted throughout the years, frequently featuring diverse shapes and facet arrangements. Given the distinct variations in the cut among various trillion-cut diamonds, it’s paramount to look at different images when comparing diamonds with this particular cut meticulously.

Types of Trillion-Cut Diamonds

Straight Side Trillion-Cut Diamonds and Rounded Side Trillion-Cut Diamonds

While all trillion-cut diamonds tend to look similar regarding their triangular shape and equal side lengths, there are a couple of variations. Some can be cut with straight sides, and some with slightly rounded sides. Each has a different look and lends itself to various aesthetic qualities, and both are very popular.

Trillion-Cut Diamonds Can Appear Larger Than Their Carat Weight

Trillion-cut diamonds generally possess a moderate-to-shallow cut, contributing to their more prominent appearance than diamonds with deeper cuts, as more of the diamond is visible from the top. Also, the elongated sides can create an illusion of a larger size, making a trillion-cut diamond an ideal choice for individuals seeking a striking aesthetic without straining their budget.

However, be aware that a diamond cut too shallow can decrease its brilliance and fire, resulting in a less remarkable visual appeal despite the larger size, so it’s advisable to steer clear of diamonds with overly shallow cuts instead of those with a moderate depth to ensure optimal beauty and radiance.

The Cost of Trillion-Cut Diamonds

Like various diamond shapes, the cost of trillion-cut diamonds can differ significantly due to colour, clarity, cut quality, and carat weight. Diamond pricing also increases considerably with increments of carat weight, meaning you can expect a much greater cost for larger diamonds.

The Rarity of Trillion-Cut Diamonds

Trillion-cut diamonds are rare, and few jewelry stores keep them in stock. In the case of fancy-cut diamonds, there have even been times when we have opted to have these custom-cut ourselves.

Ways To Set a Trillion-Cut Diamond

Several interesting ways exist to use trillion-cut diamonds in your jewelry design. The most popular is to set them as side or accent stones, usually on either side of a centre stone.
Trillion-cut diamonds can also be used as the main stone of an engagement ring or other custom diamond ring.

Also, consider using trillion-cut diamonds (and other triangular precious gems) as the focal point of pendants or other custom jewelley pieces.

General Tips When Shopping for a Trillion-Cut Diamond

When shopping for trillion-cut diamonds, there are a few things to keep in mind:

1. Find a diamond with good proportions: A diamond’s cut is one of the most important factors in terms of its brilliance and beauty. Aim to find a diamond that is not cut too deeply or too shallow, as this can affect its light performance. As mentioned previously, there are many diamonds that have been deliberately cut very shallow to appear larger on the surface, but this can lead to a duller stone.

2. Look for eye-clean diamonds: As trillion-cut diamonds are often used as accent stones, you don’t always have to find a diamond with top clarity grades. However, you should have a diamond that is eye-clean when viewed from the top down and does not display any blemishes.

3. Choose a diamond without any visible tints of colour: The goal should be to have a diamond that does not display any discernible colour differences compared to the surrounding stones. For this reason, we like to opt for diamonds in the D-H range as these diamonds are colourless or near colourless.
