Our guide to Trillion cut diamonds
Our tips for finding the Trillion cut diamond meant just for you.
A Trillion cut diamond is a triangular-shaped diamond; it features three equal sides and a flat table. Both eye-catching and unexpected, Trillion cut diamonds are faceted for fiery brilliance and known for their sleek, futuristic look. Trillions also appear larger than other diamond shapes by carat weight.
When it comes to Trillion cut diamonds and the 4Cs, prioritize cut and clarity. This shape features 37 brilliant facets and a large table, so choose excellent cut and clarity for maximal shine.
Color depends on the metal setting you choose; yellow gold engagement rings work well with near-colorless Trillion cut diamonds, while platinum and white gold pair best with colorless stones.
Trillion cut diamonds appear larger than other diamond shapes of the same carat weight, so carat should be based entirely on personal preference and the engagement ring budget you have set.
The best engagement ring setting for a Trillion cut diamond is the one that’s right for you. And although this diamond shape looks stunning in all engagement rings, there are certain designs featuring Trillions that are sought after again and again.
A Solitaire engagement ring, such as a Classic or Signature Solitaire, is perfect for highlighting the Trillion’s distinctive shape. A Signature Bezel, Hover, or Signature V engagement ring paired with the Trillion creates a sleek, futuristic look. For those wanting to buy an engagement ring that is vintage-inspired, a Three Stone or Curator engagement ring works perfectly with this unique shape.
By selecting a Trillion cut diamond sustainably grown in our zero-emission foundry, your engagement ring or fine jewelry design is a reflection of your true love and true values. A lab-grown diamond is free from human or environmental toll — which means you can enjoy its beauty, guilt-free.
