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.

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.

I had put the title as 'ONE OF A KIND' for several reasons. First off this is truly a one of a kind ring, no one except my beautiful soon to be wife will ever get the satisfaction of wearing such a treasure. Second it comes from a one of a kind company, a company who sources their metal and precious stones conflict free , helping many people along the way. Not to mention planting FIVE trees with your purchase, what companies do you know sacrifices profit for such a beautiful way of business? Third which should have been first is the one of a kind customer service and business ethics. I have always been the skeptical one out of my fiancé and I, especially when it comes to online ANYTHING lol However this team of ladies is truly something special and the ones to admire. Any question or concern I may have had Maharani was right there to answer and ease each and every one of them. The ring not only made it to the United States in less then a week but it was more perfect then any of the photos had shown.(Not to mention it came all the way from Bali, Indonesia) So what I'm saying is if there is any doubt on whether to go through Gardens of the Sun, put that doubt to bed. This company is truly ONE OF A KIND and as a happily engaged man, I stand by every word. I'm still not sure if she wants to marry me more or this company more ;)

Cannot recommend enough (but at the same time want to keep it all to myself!)

Beautiful and meaningful, sparkly and colourful, sophisticated and fun. I feel very fancy when wearing this ring, which is a good thing during these grey months when neat outfits rarely leave my closet. But most of all, a true heirloom piece which I hope will stay in our family for generations. I bought the pink Ceylon spinel ring as a gift to myself, to celebrate the long longed-for birth of our firstborn daughter. As always, Tessa was extremely kind and helpful during the process of resizing the ring, and was even able to make sure the ring got engraved, even though I forgot to ask for the engraving when placing my order. I always marvel at the kindness and patience of GotS customer service, and unpacking the lovingly wrapped jewelry boxes and reading the handwritten notes truly sparks joy.

Completely obsessed

I absolutely adore my gardens of the sun ring. My fiance and I picked it out together. It's so beautiful and unique, and more than I could have dreamed... I can't stop looking at it. It arrived beautifully packaged and didn't take long to arrive.
Highly recommend gardens of the sun.

Annemieke B. (North Brabant, Netherlands)

Easy and swift communication from the start. Good advice on taking the ring measures (the ring fits really well), nice packaging, the ring was even more beautiful in real. Knowing where the pieces come from and knowing with how much love and care the ring is made, makes it a precious piece. I am saving for earings :-)
