All of the rough sapphires from Borneo are alluvial and obtained through placer mining. She'll be happy to know where each stone has been mined and cut, and that the ring was lovingly crafted by hand by skilled artisans in Java. 

Our signature ethical gold

We use 18 karat eco-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 18 karat white gold is alloyed with palladium. This white gold has a warm gray color. If you prefer that white metal look, we recommend adding rhodium plating for $50.

We're making this for you, from scratch

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).

The most unique wedding set

I dreamed of owning a hexagon diamond ring by Gardens of the Sun, years before my proposal. When it became my time to design my custom set, the team could not have been more helpful in creating a unique piece of wearable art. Maharani suggested a silver wedding band with blue sapphires to compliment my hexagon salt & pepper diamond ring set in gold - and while I had not originally envisioned my gold ring with a silver band, I was truly blown away by the end result! The rings just fit together so perfectly, and compliment each other in the most gorgeous way. I get compliments daily on how beautiful my ring set is! I've never seen another set quite like mine, and I love it even more knowing that it was designed specifically for me. Thank you to the Gardens of the Sun team for creating such a magical, dreamy set of jewelry that I will cherish for a lifetime!!

Two rings, a story, and a lot of heart.

Like every good love story, we wanted our wedding and engagement rings to be unique and true to the love that inspired them. That's a lot to ask of jewelry, and I truly believe that Gardens of the Sun is the only company that could live up to that lofty vision. Friends and family are sick to death of us talking about our rings, but every time I look at my finger I smile, and what kind of value can you place on that? The entire experience was a delight. Thank you GOTS team. We love your impeccable work!

20 times and counting!

I have been thrilled again! I have bought no less than 20 times from GOTS, and seriously never been disappointed. I've ordered several custom rings and they have been amazing at bringing my dreams to life.
Now we can't believe in that many orders (probably 50 items!) That everything has been perfect? Once, and only once, did I describ my custom ring in an unclear way. For that, I am so thankful that GOTS send a preview photo for your approval before shipping! I saw the photo and realized I explained my concept in a confusing way. After I clarified my dreams (with a drawing) they actually took the ring apart and reset it in the way I had really hoped! Thank you a million times over! For caring about my desires, your quality, your staff, and the planet. I will purchase another 50x without a hesitation!
