Sapphire

Sapphire is the September birthstone. This original love rock is a powerful stone to gather strength. Sapphire symbolizes wisdom, loyalty, and faith. She was once believed to protect your loved ones from harm.

At first glance, sapphire gleams with power and strength, but her true colors shine within kindness and hope – that’s the stone’s real secret sauce. Sapphire lets us get real because she offers great wisdom of intuitive truth, insight, and healing. A symbol of friendship and peace, and a shield from negative energy

Sapphire is a durable gemstone with a hardness of 9 on Mohs scale of hardness. It’s suitable for everyday wear and as an alternative engagement ring.

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 white gold is rhodium plated.

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.

Well worth the wait!!!!

Yohana helped me along the way. And I couldn't be more happy with how my ring turned out. Oh my goodness, I love it so much...

Beautiful

This necklace was a must have to for me. It’s my husband/love of my life/best friend birthstone. And my lucky stone! I’m a very indecisive person when I log on to this site. But while browsing, I saw this necklace and fell in love. It’s absolutely beautiful. I love the clever way the chain is designed on the pendant. And the citrine is just lovely.
I’m so happy with my purchase and with this company. If I could give 20 stars I would.

I’m obsessed

Gardens of the sun is top tier! I love this ring so much. The green sapphire and green garnet! Are you kidding me! I didn’t even know they came in green. I love it so much! I am a sucker for anything green so of course I was drawn to this ring and it’s the perfect size. I’m so happy thank you :)

I am absolutely blown away by my ring!

I'm very happy with how my ring turned out and the excellent customer service at Gardens of the Sun. I'll give some context on why i chose Gardens of the Sun. I had gotten married and my husband and I bought each other simple wedding bands. The entire process of getting married was very simple and happened fairly quickly, we had no engagement and thus no engagement rings and our ceremony was a quick solemnisation witnessed by 50 of our closest friends and family members. My husband wanted to gift me with another ring, this time with a diamond or gemstone topping it. And because of my picky nature, he let me choose the shop and design myself. Of course I wanted a gorgeous ring but what was equally important to me were three additional requirements: I wanted the ring to come from a small company, not large brands like Tiffany; I wanted the ring to improve and support the community it operates it and not just profiting the owners; and I wanted all the components of the ring to be sourced ethically. It was mightily difficult to find a company that meets my requirements and falls within the budget so I was very much over the moon when i found Gardens of the Sun on instagram!

I can't emphasize enough how beautiful the ring in person, I gasped when I first saw it. The gemstone is a 2.44 carat sapphire sourced from Tanzania. I love its details like the minor inclusions and how in different lights, it could look mossy-green or verdant green.

Thank you to the team, especially Rissa for patiently answering my numerous queries! If you're considering getting a custom ring, do it! My only advice is that it does take quite a long time (at least 10 weeks) so do factor that into your timeline!
