Custom Marquise Diamond Ring

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

Marquise cut diamonds have a lot of face-up area, making them seem larger than a brilliant cut round diamond of the same weight. The elongated shape makes your finger look longer and thinner. 

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

We’re making this for you, from scratch

Your custom marquise diamond ring will be made to order with the marquise 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 marquise cut diamond ring will be made especially for you, we don’t accept returns on custom orders. You can read our return policy here.
