Custom Ruby Ring in Ethical Gold

Design your own ruby engagement ring or self love ring.

Choose a ruby that speaks to you and let's get started!

We’re making this for you, from scratch

Your custom ruby 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 ruby 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


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.


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.

Best experience EVER

This was the best experience I’ve ever had buying jewelry. The customer service is IMMACULATE! They even offered to hold my ring while I went on a trip to make sure it arrived while I was home.

Then we get to the ring and it is even more gorgeous than I could have imagined. The quality is immaculate. The ring box is beautiful and it includes a tiny flower which is the best little touch!! I will absolutely be purchasing more from Gardens of the Sun

The perfect engagement ring!

My fiancé and I picked out my engagement ring from Gardens of the Sun and I couldn’t be happier with it. The process of picking out the stone, setting and band was so much fun, and the team at Gardens of the Sun was so helpful in sending pictures and mock-ups! I’ve received so many compliments on my ring, and it’s so beautiful and unique!

Easy process and good advice

I have only the best to say about the company and the special piece for myself that I created with them. It is every bit so special and beautyful as I could hope and expect. And the customer-service is flawless with quick and easy contacts and good advice (especially since I got second thoughts about wich size to choose).
