About Trillion Cut Lab Grown Diamonds
Trillion cut lab grown diamonds are one of the most bold, distinctive, and visually striking diamond shapes available — a unique triangular form that delivers exceptional fire, brilliance, and a modern geometric appeal unlike any traditional diamond cut. Whether used as a breathtaking center stone or as dramatic side stones flanking a larger diamond, the trillion cut commands attention and makes an unforgettable statement. At Variation, our certified collection brings you ethically created trillion cut lab grown diamonds at prices that simply cannot be matched by mined stones.
What Is a Trillion Cut Diamond?
The trillion cut diamond — also known as the trilliant cut or triangular brilliant cut — is a triangular fancy cut diamond featuring 31 to 50 facets arranged across its distinctive three-sided form. Developed in the 1970s by the Asscher family of Amsterdam, the trillion cut was designed to maximize brilliance and fire across a triangular shape — creating a diamond of extraordinary visual impact and exceptional light performance.
The trillion cut is available in two primary variations — a curved trillion with slightly bowed sides that creates a softer, more brilliant appearance, and a straight trillion with sharp, angular sides that creates a bolder, more geometric appearance. Both deliver exceptional brilliance but create distinctly different aesthetic personalities.
Why Choose Lab Grown Over Mined Trillion Cut Diamonds?

How to Choose the Right Trillion Cut Lab Grown Diamond
1. Choose Curved or Straight Sides
The most important choice for a trillion cut diamond is whether to choose curved or straight sides. Curved trillion cuts have slightly bowed sides that maximize brilliance and fire — ideal for center stone use where sparkle is the priority. Straight trillion cuts have sharp, angular sides that create a bolder geometric appearance — ideal for buyers who want maximum visual impact and a more contemporary aesthetic.
2. Prioritize Symmetry Above All
Perfect equilateral symmetry is critical for a trillion cut diamond. All three sides must be equal in length and all three angles must be equal — any deviation creates an immediately visible imbalance that detracts significantly from the stone's geometric appeal. Always choose Excellent symmetry grades and view the stone face-up before purchasing.
3. Protect the Three Points
The three pointed corners of a trillion cut diamond are its most vulnerable points — highly susceptible to chipping from everyday impact. Always choose a setting with prongs or a bezel that covers and protects all three corners. A three-prong setting with one prong at each corner is the most popular and practical choice for trillion cut diamonds used as center stones.
4. Color Recommendations
Trillion cut diamonds face up with a large surface area that can make color slightly more visible than in round diamonds. For white gold or platinum settings, choose D–F color grades. For yellow or rose gold settings, G–H color grades pair beautifully and offer excellent value.
5. Clarity Sweet Spot
VS1–VS2 clarity is the sweet spot for trillion cut diamonds — eye-clean to the naked eye while offering significant savings over Flawless grades. Pay particular attention to inclusions near the three pointed corners, as these areas are more vulnerable to chipping and inclusions are more visible at the points.

Frequently Asked Questions
Are trillion cut lab grown diamonds real diamonds?
Yes. Lab grown diamonds are 100% real diamonds. They share the same physical, chemical, and optical properties as mined diamonds and are certified by the same internationally recognized grading laboratories.
What is the difference between a trillion cut and a trilliant cut?
Trillion and trilliant are two names for the same triangular diamond cut. Trilliant is the original trademarked name developed by the Asscher family of Amsterdam in the 1970s. Trillion is the more commonly used generic term for any triangular brilliant cut diamond. Both refer to the same distinctive three-sided diamond shape.
Are trillion cut diamonds better as center stones or side stones?
Trillion cut diamonds work beautifully in both roles. As a center stone, the trillion cut delivers maximum visual impact and geometric boldness. As side stones in a three-stone ring, matching trillion cuts create a dramatic, symmetrical frame for a larger center diamond — one of the most striking and popular three-stone combinations available.
What is the best setting for a trillion cut diamond?
A three-prong setting with one prong at each pointed corner is the most popular and practical choice for a trillion cut center stone — securing the stone at its most vulnerable points while keeping the full triangular silhouette on display. A bezel setting also works beautifully and provides maximum protection for the three corners.
What is the difference between a trillion cut and a princess cut?
Both are geometric fancy cut diamonds but they differ entirely in shape. A princess cut is square with sharp uncut corners. A trillion cut is triangular with three pointed corners. The trillion cut is the more distinctive and unconventional of the two shapes — making it the choice for buyers who want maximum individuality.
Are lab grown trillion cut diamonds cheaper than mined ones?
Yes — priced up to 80% less than an equivalent mined diamond, with no difference in beauty, durability, or certification.
