Exclusively Lab Grown
Diamonds? We Don’t Mined!
We love diamonds. We just know too much about the business of diamond mining and diamond jewelry marketing to sell even one mined diamond. Never have, never will.
We believe in looking forward. Forward to love. Forward to a better planet. Lab grown diamonds are real diamonds. 12FIFTEEN lab diamonds are ethically and environmentally pure.
Customers Who Said “Yes” to 12FIFTEEN
At 12FIFTEEN, we are mindful of the earth and on a lofty mission to ensure forever. Using ethical and sustainably focused practices, we craft our jewelry to last forever — so that the earth can too.
We use lab grown diamonds exclusively, we always have, and we always will.
With 12FIFTEEN you never have to worry if your diamond is a “blood” diamond—every single diamond we use, whether a center stone or the tiniest accent stone—was grown ethically in a lab.
We are committed to reducing the overall impact of mining on the earth. All our lab grown diamonds are free from the environmental devastation associated with mining and ocean dredging, and we are also working toward 100% recycled metal.
We offer a wide selection of lab diamonds to make it easy for you to say “yes” to lab. We have collections of premium diamonds that are Certified Zero Emissions, Grown in the USA, Super Ideal cuts, and so much more. Explore our Lab Diamond Buying Guide.
Our lab diamonds are chemically identical to natural diamonds, but without the ethical implications of mining—and they cost up to 50% less. Better for the earth, and better for your wallet.
We are committed to reducing the impact of mining on the planet, and that is why we offer engagement rings made with certified recycled precious metals. We are working toward 100% recycled metals for every single item.
Today many of our pieces are made from recycled metal and have been certified by the Responsible Jewellery Council. Every day it will be more. Responsible and ethical sourcing for every component that makes your jewelry is our priority.

All of our engagement rings are set and finished by hand in our Wisconsin workshop. Our settings are handcrafted individually with meticulous care and the finest materials. With locally supplied metals and ethical lab grown stones—you can feel confident in the manufacturing of your ring.
Your lab diamond jewelry is made with love. We labor over every detail from start to finish, we handcraft with solid metal, and we don’t compromise quality for aesthetic or vice versa.
If we sell it, it’s perfect. Every piece is inspected by master jewelers to ensure it is the highest quality before shipping it to you.
Jewelry and engagement rings are often given for some of the most important moments in life. So the shipping process should be as smooth as possible. We offer free U.S. shipping and free returns or exchanges within 30 days of delivery.
We offer one free ring resizing within a year of purchase so you can checkout confidently.
For every single purchase, be it fine jewelry or rings, you get two complimentary spa days within the first year where we will inspect, clean, and polish your pieces to perfection.
Because of our high standards and rigorous product development process, we stand by our manufacturing standards. Our rings are guaranteed for life against manufacturing defects, and our fine jewelry is guaranteed for one year after purchase.
Your ring comes with a Manufacturer Defect Guarantee. For the lifetime of your ring, if there is a manufacturing defect with your setting, we will repair or replace your ring free of charge. Any damage caused by accidents or normal wear and tear can be repaired for a nominal fee.

If components are missing, repairs may incur a cost to replace those missing components. Added services such as soldering rings together or adding bishop bumps are not included.
