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.

Custom Birthstone Necklace in Silver


Customer service was amazing. They got back with me promptly, sent me a preview, and even changed something for me before sending it. The ring itself is beautiful!!

Great service and product

The team was patient in helping me finalise the design and I love the final look. It's beautifully made and I received it earlier than expected. It was a joy from start to finish.
