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

Your Borneo sapphire ring will bemade to order with the sapphire of your choice inaround 8 to 12 weeksYou'll receive a photo before we ship it out. The price is for one finished ring in 18 karat eco gold.

Since your ring will be made especially for you, we don’t accept returns on custom orders.

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!

Heléne (Kronoberg County, Sweden)
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).
