What is a Trilliant Shape Lab Diamond?

A trilliant shape lab diamond (sometimes called trillion or triangular cut) is a triangular diamond with three equal sides, typically with 31–50 facets. The cut can feature either straight or slightly curved edges, giving the diamond a modern, geometric look while still radiating brilliance.

First developed in Amsterdam during the 1960s, the trilliant cut quickly gained popularity for its bold symmetry and versatility. Today, it’s used both as a standalone centerpiece and as accent stones in three-stone settings.

Lab-grown trilliant diamonds carry the same fire, brilliance, and durability as mined stones, but are ethically created, sustainable, and more budget-friendly.

Why Choose a Trilliant or Tringle Shape Lab-Grown Diamond?

The lab-grown trilliant cut diamond is striking for many reasons:

• Unique Sparkle: Triangular shape paired with brilliant faceting delivers intense fire.

• Modern Style: Perfect for those who want something different from traditional round or square cuts.

• Versatility: Works as a dramatic center stone or sleek side stones.

• Smart Luxury: Lab-grown means you get a larger stone or better quality within budget.

Trilliant Shape Lab Diamond vs Natural

When comparing a Trilliant Shape Lab Diamond vs Natural Diamond, the main differences lie in cost and origin, not beauty.

• Sparkle: Both lab and natural trilliants deliver the same fire and brilliance.

• Price: Lab-grown options are typically 30–40% more affordable.

• Ethics: Lab-grown diamonds are conflict-free and created with a smaller environmental footprint.

Price & Value of Trilliant Shape Lab Grown Diamond

When it comes to Trilliant Lab Diamond Price, this shape is one of the most efficient cuts for face-up size. Because of its shallow depth and triangular design, a trilliant often looks larger than other diamonds of the same carat weight. This means you get the illusion of a bigger stone while spending less compared to more traditional cuts like round or princess. Lab-grown trilliants further enhance this value by offering the same fire and durability as mined diamonds but at a fraction of the price.

That affordability gives buyers room to explore affordable trilliant lab diamond rings with more flexibility. You can move up in carat size, choose a premium setting, or even customize your design while staying within budget. Beyond cost savings, lab-created trilliants are also conflict-free and environmentally conscious, making them a sustainable choice. In essence, they deliver a rare mix of bold design, ethical sourcing, and financial value, proof that a unique cut can still be a smart investment.

Buying Guide – What to Look For

Trilliant diamonds have specific considerations when shopping for the perfect stone:

1. Cut: Symmetry is essential. The three sides should be even, and the facets should be precisely aligned for maximum sparkle.

2. Carat: Trilliants tend to appear larger than their carat weight due to their wide spread.

3. Color: Their brilliant faceting hides color well. Near-colorless (G–H) usually looks stunning.

4. Clarity: Inclusions are harder to spot in this shape, but higher clarity grades ensure a crisp, clean look.

Pro tip: Because trilliant points are delicate, choose a secure setting with protective prongs.
