Join us as we explore why the trillion cut might be the perfect choice for your next diamond purchase.

What Is a Trillion Cut Diamond?
A trillion cut diamond is a triangular-shaped diamond with brilliant faceting that creates exceptional sparkle and fire. At Labrilliante, we specialize in creating these stunning lab-grown diamonds that feature a perfect equilateral triangle shape with either straight or slightly curved sides. The trillion cut (also known as trilliant or triangular brilliant) typically features between 31 and 50 facets, strategically arranged to maximize the stone's light performance and visual appeal.
One of the most remarkable characteristics of trillion cut diamonds is their impressive face-up appearance. Thanks to their broad, open shape, trillion cuts often appear visibly larger than diamonds of comparable carat weight in other shapes. This gives you more diamond for your money—a significant advantage when selecting lab-grown diamonds at Labrilliante. While trillion cuts can serve as striking center stones in engagement rings, they're also frequently used as side stones or accent diamonds, where their unique triangular shape creates beautiful geometric contrast with other diamond shapes.
The trillion cut's distinctive silhouette makes it particularly attractive to those seeking a diamond that stands out from traditional options. The versatility of this cut allows it to complement both modern, minimalist designs and more elaborate, vintage-inspired settings.
History and Origins
The trillion cut diamond has a fascinating evolutionary journey that spans several decades. Originally developed in Amsterdam, which has long been a center for diamond cutting innovation, this distinctive triangular shape began gaining mainstream popularity in the 1960s when it was trademarked as "Trilliant" by the Henry Meyer Diamond Company in New York.
The terminology surrounding this cut can sometimes be confusing. While "trillion" is the most commonly used term today, "trilliant" was the original trademarked name and is still used interchangeably in some contexts. At Labrilliante, we generally refer to our lab-grown triangular diamonds as "trillion cut" to align with contemporary industry terminology, though you may hear both terms used by diamond professionals.
Over time, the trillion cut has evolved from being primarily used as a side stone to becoming a sought-after center stone option for those seeking distinctive engagement rings and jewelry. Its modern appeal has grown substantially in recent years as consumers increasingly seek alternatives to traditional round brilliants. At Labrilliante, we've witnessed firsthand the rising demand for trillion cut lab-grown diamonds, particularly among style-conscious buyers who appreciate geometric designs and architectural aesthetics.
Trillion Cut Diamond Characteristics
The exceptional brilliance and unique appearance of trillion cut diamonds stem from their specific proportions and faceting pattern. At Labrilliante, our master cutters optimize each lab-grown trillion diamond to achieve the perfect balance of light performance and visual appeal.
The ideal trillion cut diamond features the following characteristics:
- Facet Count: Typically ranges between 31 and 50 facets, with the most common configuration being 44 facets (25 on the crown and 19 on the pavilion).
- Depth Percentage: The optimal depth for a trillion cut falls between 32% and 48% of the width. At Labrilliante, we aim for the 40-45% sweet spot to maximize brilliance.
- Table Size: The ideal table (top flat surface) should occupy between 50% and 70% of the width of the diamond. Larger tables create more brilliance, while smaller tables can enhance fire.
- Length-to-Width Ratio: The perfect trillion cut is an equilateral triangle with a 1:1:1 ratio, ensuring symmetrical beauty from all angles.
- Symmetry: Exceptional symmetry is crucial for trillion cuts, as any imbalance becomes immediately apparent in the triangular shape.
Trillion cut diamonds exhibit two primary variations:
- Edge Profile:
- Straight edges create a more modern, geometric look
- Curved edges produce a softer, more flowing appearance
- Corner Treatment:
- Pointed corners offer a classic, dramatic look but require protective settings
- Rounded or beveled corners provide enhanced durability with a slightly softer aesthetic
At Labrilliante, our lab-grown trillion cut diamonds are renowned for their exceptional face-up size advantage—appearing up to 15% larger than round brilliants of the same carat weight. The broad, open table and shallow depth that characterize the trillion cut allow for maximum spread, giving you more visible diamond for your investment.
Trillion Cut Diamond Ideal Proportions
Feature | Ideal Range | Impact on Appearance |
---|---|---|
Depth % | 32-48% | Affects brilliance and fire |
Table % | 50-70% | Influences face-up appearance |
L/W Ratio | 1:1:1 | Determines symmetry and visual appeal |
Facet Count | 31-50 | Affects light performance |
Symmetry | Excellent | Critical for overall beauty |

Trillion Cut Diamond Quality Factors
When selecting a trillion cut lab-grown diamond at Labrilliante, understanding the key quality factors will help you make an informed choice that delivers exceptional beauty and value.
Cut Quality
The cut quality is arguably the most significant factor affecting a trillion cut diamond's beauty. Unlike round brilliants, trillion cuts don't receive standardized cut grades from gemological laboratories. At Labrilliante, we assess trillion cuts based on:
- Symmetry: The three sides should be equal in length, creating a perfect equilateral triangle.
- Polish: A excellent polish grade ensures the facets are smooth and reflective.
- Facet Alignment: Precisely aligned facets maximize light performance.
- Proportions: The ideal depth-to-width ratio balances brilliance and face-up size.
Our gemologists specifically select lab-grown diamonds that can be optimally cut into trillion shapes, ensuring superior light performance.
Clarity
The trillion cut's large, open table and shallow depth make inclusions more visible than in deeper cuts. When selecting a trillion cut diamond:
- VS1-VS2 clarity grades offer an excellent balance of value and eye-cleanliness.
- SI1 clarity can be a good value option if inclusions are located near the edges.
- VVS2 or higher recommended for larger trillion cuts (over 1.5 carats).
At Labrilliante, we carefully assess each lab-grown trillion diamond to ensure inclusions don't detract from the stone's beauty, regardless of the technical clarity grade.
Color
For trillion cuts, color becomes more visible due to their open facet pattern:
- G-H color grades offer exceptional value while appearing colorless in most settings.
- D-F colors are recommended for platinum or white gold settings where color differences become more apparent.
- I-J colors can be beautiful choices when set in yellow or rose gold, which complement warmer diamond tones.
Certification
All Labrilliante trillion cut lab-grown diamonds come with respected third-party certification from either:
- GIA (Gemological Institute of America)
- IGI (International Gemological Institute)
These certificates verify the diamond's quality specifications and confirm its lab-grown origin.

FAQ Trillion Cut Lab Grown Diamonds
Yes, trillion cut lab-grown diamonds make excellent engagement rings, especially for those seeking a modern, distinctive style. At Labrilliante, we recommend secure settings like bezels or V-prongs to protect the points while showcasing their unique triangular brilliance. Their larger face-up appearance also provides more visual impact per carat than traditional round diamonds.
Trillion cuts create striking combinations with other gemstones due to their geometric contrast. At Labrilliante, we've found they pair exceptionally well with round sapphires, oval emeralds, and square moissanites. The trillion's clean lines and faceting pattern create dynamic light interactions when set alongside colored gemstones, making them ideal for unique, personalized jewelry designs that combine different materials.
A high-quality trillion cut diamond should have perfect symmetry with equal sides, excellent polish, proper proportions (depth 32-48% of width), and VS1-VS2 clarity or better. At Labrilliante, we specifically look for crisp facet junctions, exceptional light return, and no visible inclusions. The points should be sharp and well-defined, and the diamond should display vibrant fire when moved under light.
A 1-carat lab-grown trillion cut diamond typically costs between $1,800-$2,300 at Labrilliante, depending on color and clarity grades. This represents approximately a 30-40% savings compared to mined diamonds of the same specifications and about 10-15% less than round brilliants of comparable quality.
Yes! At Labrilliante, we can custom-cut trillion diamonds from lab-grown rough to specific proportions and dimensions. This allows for perfect matching in multi-stone jewelry and enables us to optimize each diamond's unique crystal structure for maximum brilliance and size. The custom cutting process typically takes 2-3 weeks and allows for personalization to your exact specifications.
Trillion cuts do reveal color more readily than deeper shapes like round brilliants due to their shallow depth and large table. For white metals, we recommend G color or better for trillion cuts. However, this characteristic creates an interesting advantage: trillion cuts can beautifully enhance fancy colored lab-grown diamonds, making them appear more vibrant and saturated than other shapes with the same color intensity.
The triangular shape of trillion cut diamonds carries rich symbolism across cultures. Many couples choose them to represent the union of past, present, and future or mind, body, and spirit. In sacred geometry, triangles symbolize harmony and balance. At Labrilliante, we've noticed increased interest in trillion cut diamonds for anniversary gifts representing the three phases of a relationship: foundation, growth, and enduring commitment.
With proper setting, trillion cut diamonds are surprisingly durable for everyday wear. Their unique triangular structure distributes force differently than other shapes, making them resistant to certain types of impacts. At Labrilliante, we recommend bezel or V-prong settings that protect the points while still allowing maximum light entry. With these precautions, your trillion cut diamond can maintain its beauty for generations.
