Ring Size Help

Be like the trees, the moon, the neon colored beetles in the dirt. Live knowingly. Trust that every moment, you change a little, grow a little, even if unnoticed. Until one day, looking back, the magnificent explosion that is your life takes your breath away. 


  • 18 karat yellow gold, mined with traditional and low impact practices by indigenous Dayak women in Central Kalimantan, Indonesian Borneo, who receive fair pay
  • 0.35 ct old mine cut diamond from South Kalimantan, Indonesian Borneo, comes with certificate from the South Kalimantan Gem Laboratory (SKGL)
  • Six Canadian icy white diamonds in the band
  • Conflict free and ethically sourced materials
  • One of a kind


The eye catcher of this ring is an oval diamond from South Kalimantan, Indonesia. The oval diamond weighs a third of a carat and has been cut by hand in Martapura, South Kalimantan. The diamond is mostly clear with some small inclusions, it could be called a very light salt and pepper diamond, although it's a lot less included than most. The cut is slightly irregular and has a lot of character. A beautiful stone if you're into antique diamonds. 

According to the accompanying diamond certificate: 

  • Cushion brilliant cut
  • Weighs 0.35 ct
  • Measures 4.74 x 4.64 x 2.06 mm
  • Cut grade is fair
  • Clarity SI1 with noticeable inclusions, namely feather, cavity and bearded girdle
  • Faint yellow color M

The ethical diamond has been securely set in 18 karat gold. This gold was responsibly mined by indigenous Dayak women in Central Kalimantan, who receive a 20% premium for their gold (as compared to the national gold price at the time) in exchange for using low impact techniques that are free of mercury and cyanide. 

We only get small batches of this gold, because traditional gold panning means they only get very small particles of gold, which combines into less than a gram a day. Your ring is a true labor of love. 

Would make a wonderful ethical engagement ring or wedding band for the couple who cares about responsible sourcing and where the materials came from. After all, a ring that's supposed to symbolize your love should leave you feeling empowered and guilt-free.

Thank you for your article!

I recently bought a 1.5 carat blue diamond that was color enhanced and I thought I was taken advantage of because it wasn’t a “natural” diamond. After reading your article I feel much better about my purchase and will have the stone mounted.

Perfect companion ring

This is my second nesting band from Gardens of the Sun. I love how they work with a variety of other rings. Well made, it will last forever. Thank you so much!

Words can't even begin to describe...

I am so very grateful for Sovi and the rest of the Gardens of the Sun family...what a beautiful experience and an absolutely breathtaking engagement ring, handcrafted to perfection. And don't even get me started on the ring box! What a blessing it was to find a box that is just as beautiful as the ring that was inside.

I will forever be grateful for my Gardens of the Sun adventure and cannot wait to share this beautiful ring with my beautiful darling.

Thank you again for everything :)

With love,

A future heirloom

My partner and I actually designed this ring together to be my engagement ring because he was worried about picking a ring without my input (I would be the one wearing it forever, not him). The whole process of designing the ring was incredibly easy because we could look at all of our options and take our time in deciding what stone(s) and which style we wanted exactly. Not only was the designing process easy and less intimidating than going to a store, but it was awesome to be able to know where exactly each of the materials were sourced, and the process in which it would be made. I love knowing that this ring was made ethically by a company that truly cares about every step of the process, from the point at which they received the materials to the point where I received the ring. We are so happy we decided to make our engagement ring through the team at Gardens of the Sun because this future heirloom deserves its story of being made without conflict by a company that is devoted to changing how jewellery can and should be made.
