Trilliant Cut Diamonds: Sharp Lines, Maximum Sparkle
The trilliant or trillion cut is a triangular diamond with high brilliance and a distinctive geometric look. Learn why it is loved as a side stone and a bold centre stone.
What Is a Trilliant Cut?
The trilliant cut is a triangular diamond with either straight or curved sides and brilliant-style faceting. It is prized for its large face-up size and high sparkle. We often use trilliants as side stones next to larger centre stones. View our collection.

Choosing Trilliant Diamonds
The sharp corners chip easily, so look for V-shaped prongs or bezel protection. Colour and clarity grades can be slightly lower because the triangular shape hides imperfections well. Ask us for matching trilliant pairs.

Is a trilliant the same as a trillion?
Essentially yes. Trilliant is the original trademarked name; trillion is the generic term. Both refer to triangular brilliant-cut diamonds.
Do trilliant diamonds chip easily?
The corners are vulnerable. A setting with V-prongs or bezels protects them perfectly.
Are trilliants good engagement ring centre stones?
Yes, especially for clients who want a modern, geometric look. They look larger per carat than round brilliants.
