A trillion-cut diamond makes a distinctive center stone, but finding a good one can be difficult. Learn how to choose the best quality stone for your ring.
5 Minute Read
Working with a custom jeweler like CustomMade will help you find the perfect trillion to feature in your ring. Plus, the ring will be custom-fit to your diamond, so there's no headaches when setting the stone.
Every diamond shape has its benefits and drawbacks. Ultimately, you should get the diamond shape that works best for your style.
There are plenty of good reasons to get a trillion-cut diamond. Did you know that a trillion-cut diamond will look larger than a round with the same carat weight? In fact, it doesn't just look larger, it actually has a surface about 12% bigger. A trillion has the largest face-up area of any diamond shape, except a marquise.
A trillion will also cost much less than a round of the same weight. Round diamonds sell at a premium due to high demand. So, choosing any fancy shape — any finished shape other than round — can save you some money.
Finally, you'll rarely see trillions as center stones, so your ring is sure to be an eye-catcher. If you have eclectic tastes, there's no better reason to buy a trillion-cut diamond. The sharp points and steep angles also make this shape a great option for a modern look.
The trillion does have some physical weaknesses. Although diamonds are famously resistant to scratching, the sharp corners of a trillion-cut diamond are likely to chip and break. Make sure to have the stone placed in a protective setting, such as V-shaped prongs or a bezel.
Perhaps the most significant drawback to choosing a trillion is limited availability. Major retailers like James Allen or Blue Nile don't carry trillion-cut diamonds. Instead, try working with a custom jeweler like CustomMade. They can source the perfect trillion-cut diamond for your ring.
Unlike round diamonds, trillions don't have any specific guidelines for good cut quality. Instead, you'll just have to shop around for a trillion that looks good. If you're buying online, that means you'll have to find a vendor that provides good pictures and videos of your diamond. If you're shopping at a brick-and-mortar store, make sure the merchant shows you your diamond from all angles.
Limit your search to certain proportions. Make sure the total depth percentage is between 32 and 48% to prevent light leakage. Limit the table width to 50 to 70% of the diamond width, too. Finally, you'll want a length-to-width ratio of 1.0 to 1.1 to avoid an off-shape trillion.
Symmetry is essential to shape appeal, but it's not the only important aspect. You should consider the type of trillion shape you want for your ring.
Do you want flat sides or rounded sides? Flat sides will give your ring a strong geometric look, while rounded trillions are generally preferred for a diamond center stone. Rounding can also be slight or prominent, whatever fits your style.
Consider the type of corners you'd prefer, too. Most trillions have sharp corners that are susceptible to damage. On the other hand, some have cut-off corners that are less likely to break. However, these will give the diamond a different look.
Next, look for symmetry. Trillions should be equilateral triangles, so all three angles should be equal and all three sides should have the same length.
The back facets should provide light return in a symmetrical fashion, too. If one area is more sparkly than another, this indicates poor cut quality.
Rounded sides should be equally round and without bulges.
Since trillions are a brilliant cut, they should hide inclusions well. An SI clarity trillion will very likely appear eye-clean when set in a ring.
That said, since a well-cut trillion is so hard to find, we recommend keeping your search as open as possible. Consider every clarity grade from SI2 and up, so you can find a diamond with good shape appeal and top sparkle.
Like clarity, color is a secondary concern. Ultimately, you just want the diamond to look white in your ring. Jewelry metals can have a major effect on what a diamond's color looks like in its setting. So, for white gold and platinum settings, stick to a diamond color grade of H or better. In yellow gold or rose gold settings, a color grade of J or better will look beautiful.
