Let us build the ethical dream ring for the woman of your dreams. It's important to her that the ring she wears for the rest of her life to symbolize your commitment to her, has been ethically made and sourced. 

Each sapphire crystal was mined in Dry Cottonwood Creek, Montana. The crystals were then heated in the USA. Many of them have orange coloration due to higher levels of magnesium in those areas of the crystal. 

These stones are more flat and therefore not really suitable for traditional brilliant cut. Each stone was cut by hand in Ratnapura, Sri Lanka.

Your rose cut sapphire ring will be made to order with the Montana sapphire of your choice in around 6 to 8 weeks. The design of this custom ring is where you come in! 

The curved diamond nesting band is not included.

      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.
