Custom Australian Opal Ring in Gold

Design your own opal engagement ring or self love ring.

Choose an Australian opal that speaks to you and let's get started! Each opal is a solid, natural opal and has been responsibly sourced from Australia.

Opal

Opal is the October birthstone. Flashes of color dancing in a glimmering stone, there’s not much that needs to be said about its beauty. This gemstone is as versatile as it is colorful – use it for playfulness and strength, tenderness and truth, to amplify your karma and keep your cool all at once.

Opal absorbs and reflects light as it dances, and likewise, it picks up thoughts and feelings, desires and buried emotions, amplifying them and returning them to the source. Opal helps you to let go of patterns of fear, anger, negativity and self-harm. If you need to let go of the one who doesn’t deserve you, have faith in Opal and this too shall pass.

With a hardness of 5.5 to 6.5 on the Mohs scale, opal is a softer gemstone. This means that opal can easily be scratched, even by dust particles. High heat and sudden temperature changes can cause opal to crack. Because opals are porous you should avoid contact with chemicals, cosmetics and household cleaners while wearing your opal. Don’t wear your opal jewelry during physical activity, like sports or gardening. The only safe way to clean opal is with warm, soapy water.

We’re making this for you, from scratch

Your custom shape gemstone ring will be made to order with the gemstone of your choice in around 8 to 12 weeks. You'll receive a photo before we ship it out. The price is for one finished ring in 18 karat eco gold.

Since your shape stone ring will be made especially for you, we don’t accept returns on custom orders. You can read our return policy here.

Your custom ring design

Metal

You can choose from 18 karat yellow gold, rose gold or white gold. We use 18 karat ethical 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.


Ring size

We use US ring sizes.

Setting

You can choose between a bezel setting, which has the gold all the way around the stone and a prong setting, where small claws hold the stone. Not sure which setting is right for you? Compare bezel vs prong setting here.


Diamonds in band

Want to add some extra sparkle? Pave diamonds in the ring band can really elevate the look of your ring. Choose between salt and pepper diamonds (the rebellious budget option) or white diamonds (G-H color, SI clarity).

Engraving is on us

We offer complimentary engraving on the inside of your ring to personalize it even more. Our team will reach out to you after your purchase for details.

Conflict free diamonds

The diamonds used in this jewelry have been purchased from legitimate sources not involved in funding conflict and in compliance with United Nations resolutions. Based on personal knowledge and/or written guarantees provided by the supplier of these diamonds they are conflict free and mined in accordance with the Kimberley Process.

Gardens of the Sun goes beyond conflict free. Since our sourcing policy came into effect in November 2018 we only purchase diamonds from known origins. We avoid sourcing diamonds from Angola, Democratic Republic of Congo, Ivory Coast, Liberia, Russia (last purchased in 2019), Sierra Leone and Zimbabwe.

Is it an engagement ring?

Are you planning on using this as an engagement ring? Ask us to keep the exact measurements of your diamond. This way, if you decide to also get a wedding band or nesting band from us, we can help make sure it fits perfectly.

Birthstone ring in silver

My partner ordered my ring for my 30th birthday gift and it's beautiful! I chose my birthstone tourmaline, his as emerald, and then a moonstone to contrast with the greens. It's just like the photos and is even better in person. I also got a nesting silver ring to compliment it and it looks lovely with and without it. This is my second ring from you guys, as my partner got my engagement ring here last year. <3 Very happy with my purchase, and I love supporting Gardens of the Sun.

Birthstone Ring in Sterling Silver

So happy with my Birthstone ring! Combined sapphire with citrine for the two stones. Sapphire for the month of September and Citrine for the sign of Libra. Great communication throughout the process. And the ring was sized just right. This is my second purchase from Gardens of the Sun. I’m sure to be back again. Thank you.

Tiny birthstones... did NOT match the photo example or mockup

The ring I received was definitely more of a STACKER... not a ring like the one pictured in the Double Birthstone Ring example photo. The stones I received are extremely tiny, about the size of the band. If I knew I'd be spending this much and waiting this long for a tiny stacker ring I wouldn't have ordered it. I was expecting something similar in size to the image on the website, the stones are much bigger.

I am disappointed because I ordered this for the birth of my daughter, who is due in one week. I received it just in time after waiting 2 months for it. When I opened the box I was so underwhelmed, I wish I hadn't been anticipating something completely different this entire time. Even the stones in the mockup they sent were a lot bigger. I can't emphasize just how small the two birth stones are.

The design was right and the customer service was very friendly but the size of the stones is so unacceptable. Disappointed...

Hi Sofia,

Thank you for your honest review. I’m so sorry to hear the gemstones were smaller than you expected.

Did you find the birthstone size chart on the product page? There you can find the size of each birthstone in mm. We also sent you a photo of the ring being worn before shipping it to you. We take these photos so our clients can see the actual size of the stones on a finger. Did you find this portrayed the size of the stones better than the mockup? Is there something we could have done to give you a more accurate idea of the size of the stones?

Please know that we're taking your feedback seriously. This helps us to improve.

The mockup was taken up close and prepared on paper instead of a real ring. I'm going to get the team together and see if it would make sense for us to put the stones on a real ring and provide both up-close and full finger photos for future mockups.

I understand your frustration as this is such a special ring for you. Did you receive my email with my offer? I hope we can make this right for you, Sofia!

Thank you for taking the time to share what we can do better.

With love,
Meri
