Highest quality diamonds, the purest conscience, and a strong, personal connection.

Hi! We’re Julia and Julia. We’re the German duo behind our Seattle based company Juwels & Co. We've been good friends ever since we met 16 years ago while studying photography. For more than 10 years now, we've both been working in the high-end luxury industry. Julia M. as a former Editor at Vogue Germany and Julia V. as Art Director for Airbnb Luxe.

We share a passion for high quality products and design. We truly believe that a luxurious life does not have to be at the expense of nature and our fellow human beings. For us, luxury is about using privilege to invest in the future. It is about ensuring that future generations can enjoy a healthy and comfortable life.

Values that are still rare to find in the traditional Diamond industry as they are stuck in old patterns. This is the reason for the foundation of Juwels & Co. With the future in mind, our mission is to raise awareness for sustainable alternatives by investing in lab-grown diamond jewelry that’s both beautiful and built to last a lifetime.

All of our rings are made from recycled gold and lab-grown diamonds, which are physically identical to mined diamonds without harming the environment or financing any wars.

For generations to come, we want to be the leading Jewelry Brand for changing shopping habits for luxury goods.

When you buy from us, you can feel good knowing that you are not only helping to protect the environment, but you are also helping to make it better. Our lab-grown diamonds are conflict-free. In fact, our lab-grown diamonds actually help to reduce air pollution by using recycled carbon dioxide. So, by choosing our diamonds, you can be sure that you are making a positive impact on the planet.

In total, air emissions on a single carat of mined diamonds are 1.5 billion times higher than those of a lab-grown one. While the production of mined diamonds requires 125 pounds of carbon to create 1 carat, lab-grown diamonds need only 6 pounds of carbon.

These are great news, but we are still aware that lab diamonds are not 100% sustainable at this time. Our vision is to go one step further by using a new technology that removes carbon from the atmosphere. Until 2025, our goal is to become one of few diamond jewelry companies that a registered as a BCorp.

We want to keep pushing this industry forward, advocate for better practices, and offer more value.


There's no need to know it all – that's what we're here for. We’re certified jewelry experts with a diploma from the Gemological Institute of America (GIA).We specialize in lab-grown diamonds and sustainable and ethical jewelry and we love to share our knowledge. With our expertise and resources, we’ll help you create the ring of your dreams. 


Transparency in a supply chain is the first step toward improving the rights of human beings.Our commitment to transparency extends to all aspects of our business which is why we’re open about our lab-grown diamond origins, quality, and cost. All of our products are 100% traceable.


Trust is important when making any purchase but when it comes to buying diamonds, it’s even more so. We are eager to gain your trust by sharing our knowledge, and resources, and even have you part of the full design process. We are committed to helping you find the perfect ring.


We care about our customers, our planet, and humanity in general. That's why we only offer high-quality, recycled gold, lab-grown diamonds and full traceability. It’s time to set an end to diamond mines everywhere. Diamond mining is both harmful to the planet and incredibly unsustainable. About one ton of rock must be processed to recover 0.5 carats of rough diamonds. Thanks to modern technology there are endless, outstanding opportunities to live a luxurious and sustainable lifestyle.

We are committed to Sustainability

There are often dangerous and environmentally damaging methods used to obtain the raw materials for diamond jewelry pieces. The mining of diamonds and gold affects both people and the environment. As a result, jewelry is rarely sustainable and causes a lot of carbon emissions.

Sustainability is all about making conscious decisions that positively impact our planet and future generations. Choosing environmentally friendly jewelry may sound like a small step to take but can add up to make a big difference. 

When we set out to make a sustainable diamond business, we really set out to redefine luxury. We know it’s possible to live a beautiful life of luxury andtake care of our planet. 

In order to make our contribution to climate protection, we use recycled 14 carat gold and lab-grown diamonds that consume much less energy and resources than conventional diamonds. However, in order to offer you a 100% carbon neutral product, we offset our remaining carbon emissions for you by working with climeworks.

Our Diamond Quality Standarts 

We are expert in understanding diamonds. With years of experience in the diamond industry, we are highly trained and knowledgeable about the 4Cs - Cut, Clarity, Color, and Carat. We understand the the process of finding the perfect diamond can be very stressful. Thats why we offer predetermined diamond quality standards, certified by GIA and IGI.

CARAT  -  we offer all-carat weight
Diamonds are measured by their carat weight. Large diamonds are rarer than small ones. Besides the other 3 Cs, the carat is based purely on personal preference.

CUT- Excellent
When a diamond is well-cut, light travels through it in a breathtaking way. That's why we only offer excellent-cut diamonds. 

During the growing process of a diamond, they can form natural marks called inclusions or blemishes. We recommended diamonds from FL (flawless - no marks) to VS2 (very slightly included marks).

The majority of diamonds used in jewelry are almost colorless with a slightly yellowish or brown tinge. Color is described using different letters – we recommend diamonds from D (colorless) to J (near colorless).

Pushing old boundaries of the Diamond Industry and taking it further with Aether Collaboration

In addition, we are proud to be one of the first jewelers to use carbon-negative diamonds. This completely new process of producing genuine diamonds has so far only been accessible to a few jewelers. We offer climate-positive diamonds exclusively in personalised rings such as engagement rings or wedding bands.
