Custom Polki Diamond Ring

These cloudy diamond slices are hand-cut and will be set just for you onto a dainty sterling silver or gold band. Brimming with personality, these stones carry a slice of their origins – from the wilds of Indonesian Borneo. Ethically sourced, born in Kalimantan, designed in Bali and handcrafted in Jogjakarta, each ring tells a rich tale only wanderers can know. 

Now the design...

Each diamond slice has a few facets over the top, but is rough on the sides and flat on the bottom. This antique cut was common in the old days. These diamonds have imperfect, ragged edges, as well as surface imperfections, pits and chips. If you want a flawless, perfect diamond, these are not for you.

Diamond setting

  • Classic bezel setting with the silver all the way around the diamond 
  • Basket prongs. A basket setting is a type of prong setting, but with a little difference when viewed from the side or profile. The prongs will rise up from a base or 'basket' into which the gemstone is set.

    Your diamond can be set vertically (North to South, long side up as in the group photo) or horizontally (East to West, long side aligned with the ring band).

    Our white gold is rhodium plated, and the rhodium plating tends to wear off the prongs. So white gold prongs need more care and maintenance. 

    Band shape

    • Half round band, flat on the inside and rounded on the outside, for a comfortable fit. Around 1.8 mm wide. 
    • Round band, this band tends to spin more and is not recommend if your knuckles are wider than the part of your finger where the ring sits. Around 1.3 mm wide. 

    Additional small stones in the band (gold only):

    • Plain band, no additional diamonds
    • Small sparkling white Canadian diamonds (G-H color, SI clarity) - you choose how many

    The price will be automatically adjusted depending on the stones and design you choose. 

    Engraving is on us!

    For diamond rings in gold, we offer complimentary hand engraving up to 24 characters on the inside of your gold diamond ring to personalize it even more. This is only possible for half round bands, as the round bands are too dainty, and can be selected in the dropdown menu.

    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 custom diamond ring will bemade to order with the Borneo diamond of your choice in 5 to 8 weeks for silver or 8 to 12 weeks for goldYou'll receive a photo before we ship it out. The price is for one finished ring in sterling silver or 18 karat eco gold.

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

    Surprised and delighted

    Both rings I ordered were what I expected but I really appreciated the handwritten tags and informational inserts. The box was also lovely and I love that it's made of recycled banana leaves!

    Best Case Scenario

    This company is absolutely amazing. I decided last minute that I wanted a wedding band made in addition to my custom engagement ring. I sent the ring back a few months later, and it got lost in the mail. Their customer service was AMAZING. They provided updates as soon as they got them, they reached out to everyone to find my ring, and let me know when it arrived safely. They completely suppressed my anxiety around the whole situation. They ask questions when crafting instead of making assumptions, and even sent progress pictures. I could not be more thrilled with Gardens of the Sun and will definitely be telling everyone I know about them! In addition to all this, I got to support a women run company with the same environmental views I have. It is so cool to have a story behind my beautiful, one of a kind, wedding ring and I could not be happier with the end result! They even sent a little gift at the end of the whole journey! 10/10 recommend.

    Custom Diamond Slice Engagement Ring

    I ordered a custom sliced diamond ring and another ring for my engagement ring and wedding band. There was great communication throughout the process of my rings’ creation and when it arrived it was beautifully packaged and you could tell there was love and care put into this order. I would definitely recommend purchasing a piece of jewelry from Gardens if The Sun, and plan to purchase more myself! I love that with each purchase trees are planted and that ethically sourced materials are used.

    Excellent customer service! Great products!

    These awesome ladies worked with me from the beginning and even worked with me when I made an oops and had to change things around. They were very accommodating and flexible to my needs and I couldn’t be happier with the end result!! They were very quick to respond to my (annoying, I’m sure) emails despite the time difference (USA). And shipping didn’t take as long as I’d expected either! I was finally gifted my engagement ring so I’ve been waiting to leave a review until it was official. You ladies are amazing!
