What is Diamond Foundry?
Diamond Foundry is a groundbreaking diamond manufacturer (yep, they make them) founded by M.I.T., Stanford, and Princeton engineers. They are one of Business Insider’s Most Innovative Tech Startups. And one of CNBC’s Top Disruptors. AND one of Time Magazine’s Best Inventions of 2018!
In 2012, Diamond Foundry set off on a mission to make Lab-Grown Diamonds “mainstream.” In other words, they wanted to make them accepted, affordable, and sustainable. To that end, DF engineers handcrafted highly specialized plasma technology and also built a completely solar facility. Now DF creates over 100,000 carats of sustainable, beautiful, diamond crystals per year!
Diamond Foundry Stones
Fun facts about Diamond Foundry Stones:
- They are carbon-neutral. They use no coal or oil to power their buildings!
- Diamonds come in one of 37 different shapes.
- Each diamond is faceted to ideal proportions.
- Most diamonds come with both a GCAL Diamond Certification as well as a proprietary DF Certification.
Diamond Foundry vs Real Diamond
Diamonds made by DF are real diamonds. So, they are pure carbon, just like mined diamonds, and come in all the same colors and clarities. In fact, the only difference between them is that they were born in DF’s solar-powered lab. As a result, there is absolutely no difference in the look between a Lab Grown Diamond and a natural, mined diamond. Read more here about natural diamonds vs. lab diamonds!

They’re the Most Sustainable, Environmentally Responsible Lab Diamond
Diamond Foundry’s diamonds are unique because DF is 100% carbon neutral. In other words, DF causes zero harm to the Earth. No, really. Think about that. Net-zero harm during manufacture, cutting, and even shipping and transport! What company can you think of that has that level of environmental dedication?
So, couples looking for the best lab diamond can feel great about their DF diamond. Zero greenhouse gas emission; net-zero carbon footprint. In fact, DF’s diamond creation process is so efficient, they have even been independently certified by Natural Capital Partners.
Diamond Foundry Certification
DF Diamonds come certified by both GCAL and Diamond Foundry! In other words, the DF cert gives you proof that the stone was made by them. And, the GCAL cert gives you independent (3rd party) analysis of the stone.

Example of Diamond Foundry Certificate and GCAL Certificate
Independent Analysis
Certification from GCAL provides couples with an independent, professional opinion of the gem’s quality. So, it’s not just DF that says the stone is, for example, an I/VS2. It is a gem laboratory with no horse in the race. This helps couples level the playing field when comparing diamonds. In addition, GCAL is one of the most respected labs certifying diamonds at this time. (Sadly, not all gem labs grade ethically. As a result, having a GCAL cert is a huge bonus). So, couples can be sure their DF stone really is what they say it is.
Proof of Creation
The second certificate by Diamond Foundry proves DF created the diamond. This is beneficial because couples often choose Lab Diamonds due to how sustainable and socially conscious they are. So, having a DF Certification is a solid resale point. In other words, if at some later date you choose to upgrade or sell your DF Lab Diamond, other eco-conscious couples may also prefer DF over other brands. This Diamond Foundry Certification proves your stone was created with zero carbon footprint.
How Can I Buy a DF Lab-Grown Diamond?
Most Lab Diamonds are marketed merely as “Lab-Grown Diamonds” or “Synthetic Diamonds,” not by brand, such as those from Diamond Foundry.
