Amazing service on custom wedding band

I ordered the engagement ring for my now fiance from Gema&Co and she loved it! We looked at wedding bands in person and she really enjoyed thicker band designs. I wanted to try and order the wedding band from Gema&Co as well so I reached out and they worked with us on customizing the small curve to be substantially wider! They even provided a 3D rendering showing the wedding band paired with the engagement ring. We ordered it with custom engraving and everything about it turned out perfect! Plus the very fair price meant there was more money to put towards the wedding which is a great bonus!

SHE SAID YES!!!

From purchase to proposal, Gema&Co made the process so enjoyable. My now fiancé is in love with the ring and my friends and family all agree it suits her perfectly. The ring is even more beautiful in person than it was online! I am eternally grateful to Gema&Co for their world class craftsmanship with a reasonable price tag.

Absolutely beautiful

My fiancé proposed to me with this ring yesterday at Fort Sumter National Monument in Charleston, SC. It was absolutely beautiful. This ring is so gorgeous. The band is perfect and the moissanite is stunning. I could not be happier with my ring. I love that it is ethically sourced as well.

Beautiful ring!

The 1.5ct size is a beautiful setting for a size 4.25 ring! The only thing to keep an eye out for is that these three stone settings may not work with all styles of wedding bands. If you have a particular image about how you want this to look with a wedding band consider the wedding band options before buying to make sure it will look how you want it to look!

Custom bands and excellent customer service

My engagement band is very low set so I had a hard time finding a wedding band that fits around it. My best option was to do the open pave band, but with a custom gap width. Throughout this process, Liz was extremely helpful and patient. There is also a lot of consistency in who you talk to via chat, email, etc. I had worked with Liz the whole time; she guided me through figuring out what size gap I need and any other ring accommodations to consider that I hadn’t thought of. She was super personable, as well. The ring turned out perfect, and I received it very quickly. Everything was all around a pleasant experience - highly recommend!

FAQ: Design Your Own Moissanite Ring

Have questions before you design your own moissanite ring? We have answers. If you don’t see your question below, check out our FAQs page for more.

How do I design my own moissanite ring?

You can design your own moissanite ring by sharing your vision with our team, then collaborating on the stone, setting, metal, and details until every element feels right. Start with an inspiration photo, a sketch, a link to a ring you love, or an existing Gema&Co design you'd like to modify. Our design team refines the design with you before anything goes into production.

What can I customize when designing a moissanite ring?

When designing a moissanite ring with Gema&Co, you can customize the center stone shape, size, and color, the setting style, metal type and color, band width, accent stones, and matching wedding band. You can also work from a reference photo or an existing ring and adjust specific details to make the piece your own.

Can I design my own moissanite engagement ring online?

Yes, you can design your own moissanite engagement ring entirely online with Gema&Co. Share your preferences through our contact form, collaborate with our team remotely, and review the design before your ring goes into production. You don't need to visit a showroom to create your own moissanite engagement ring.

Can I customize an existing Gema&Co ring design?

Yes, you can customize any existing ring in the Gema&Co collection by adjusting the stone, setting, metal, band style, or other details. Pick a ring from our collection and tell us what you'd change. This is a popular option for people who like a current design but want the finished piece to feel more personal.

How much does it cost to design a custom moissanite ring?

The cost to design a custom moissanite ring depends on the center stone, setting, metal, and design complexity. Because moissanite delivers brilliance that rivals diamonds at a fraction of the cost, you typically have more room to personalize the ring within your budget. We provide a quote before any work begins.

How long does it take to design and make a custom moissanite ring?

It typically takes about 2.5 weeks to design and make a custom moissanite ring once the design is finalized. More complex projects, like detailed settings or bridal sets, can take up to 4 weeks. When you build your own moissanite ring with us, we keep you updated at every step.
