Custom Triangle Diamond Ring

Design your own modern diamond engagement ring or self love ring.

A triangle cut diamond has a three-point shape. This angular diamond cut gives a modern and contemporary look. Trillion cut diamonds have slightly more curved edges and more facets than the classic triangle cut. Trilliant cut diamonds tend to look a little larger than round diamonds of the same weight.

Be aware the corners of this unique diamond cut are more susceptible to bumps and other impact, making them more fragile than the brilliant round. 

Choose a trilliant cut diamond that speaks to you and let's get started on your triangle diamond engagement ring. 

We’re making this for you, from scratch

Your custom triangle diamond ring will be made to order with the trilliant diamond of your choice in around 8 to 12 weeks. You'll receive a photo before we ship it out. The price is for one finished ring in 18 karat eco gold.

Since your triangle cut diamond ring will be made especially for you, we don’t accept returns on custom orders. You can read our return policy here.
