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 13 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.

Your custom ring design

Metal

You can choose from 18 karat yellow gold, rose gold or white gold. We use 18 karat ethical gold, which is mined and processed with traditional, mercury free, low impact practices by indigenous Dayak women in Central Kalimantan, Indonesian Borneo, who receive fair pay. Our white gold is rhodium plated.

Ring size

We use US ring sizes.

Setting

You can choose between a bezel setting, which has the gold all the way around the stone and a prong setting, where small claws hold the stone. Not sure which setting is right for you? Compare bezel vs prong setting here.

Diamonds in band

Want to add some extra sparkle? Pave diamonds in the ring band can really elevate the look of your ring. Choose between salt and pepper diamonds (the rebellious budget option) or white diamonds (G-H color, SI clarity).

Engraving is on us

We offer complimentary engraving on the inside of your ring to personalize it even more. Our team will reach out to you after your purchase for details.

Conflict free diamonds

The diamonds used in this jewelry have been purchased from legitimate sources not involved in funding conflict and in compliance with United Nations resolutions. Based on personal knowledge and/or written guarantees provided by the supplier of these diamonds they are conflict free and mined in accordance with the Kimberley Process.

Gardens of the Sun goes beyond conflict free. Since our sourcing policy came into effect in November 2018 we only purchase diamonds from known origins. We avoid sourcing diamonds from Angola, Democratic Republic of Congo, Ivory Coast, Liberia, Russia (last purchased in 2019), Sierra Leone and Zimbabwe.

Is it an engagement ring?

Are you planning on using this as an engagement ring? Ask us to keep the exact measurements of your diamond. This way, if you decide to also get a wedding band or nesting band from us, we can help make sure it fits perfectly.

Beautiful

This necklace was a must have to for me. It’s my husband/love of my life/best friend birthstone. And my lucky stone! I’m a very indecisive person when I log on to this site. But while browsing, I saw this necklace and fell in love. It’s absolutely beautiful. I love the clever way the chain is designed on the pendant. And the citrine is just lovely.
I’m so happy with my purchase and with this company. If I could give 20 stars I would.

I’m obsessed

Gardens of the sun is top tier! I love this ring so much. The green sapphire and green garnet! Are you kidding me! I didn’t even know they came in green. I love it so much! I am a sucker for anything green so of course I was drawn to this ring and it’s the perfect size. I’m so happy thank you :)
