What is a lab grown diamond?
Our diamonds are lab grown diamonds, they’re grown in a laboratory like flowers in a greenhouse. The diamond that comes out of the lab is exactly the same as a rough diamond that is mined. After that, the diamond is cut and polished just as any other diamond would be. It’s the same.
So, is it a diamond?
Yes. Lab grown diamonds are made of carbon, just like diamonds pulled from the ground. They’re identical chemically. No different.
Why are lab diamonds better than mined diamonds?
Our lab diamonds are not only better for the environment because they are not mined, but they are of the highest quality, at a lower price than mined diamonds. You can be confident that you’re getting a great value for your lab diamond.
What are the 4C’s?
The 4C’s are what all diamonds and lab diamonds are graded on to determine quality.
Color: measures the degree of colorlessness. Stones are graded on a scale that ranges from D (colorless) to Z (yellow).
Cut: refers to how well it returns light. We only provide loose lab diamonds that are Good, Very Good, Ideal and Super Ideal. Learn more here.
Clarity: refers to the number, size and position of inclusions and blemishes. Diamonds are graded on a scale from Flawless (no inclusions) to I3 (obvious inclusions).
Carat Weight: measures a diamond’s apparent size. Price increases with carat weight because larger diamonds are more valuable.
What does it mean to have a certified lab diamond?
Our lab diamonds are sent to IGI, GIA, GCAL, or an independent reporting agency to be graded and certified, just as mined diamonds are. Certified lab diamonds have a laser engraved certification number that is invisible to the naked eye, but can be seen under magnification (and appears on your paperwork). Laser inscriptions provide peace of mind when making a lab diamond purchase.
Can I purchase a loose lab diamond?
Of course. You can purchase any of our loose lab diamonds by themselves.
Why are your rings better?
Our rings are better because our quality is better. Unlike large batches of mass-produced rings, our settings are handcrafted individually with the finest materials. Our superior quality and low price point set us apart from the rest.
What metal types do you offer?
Any of our settings can be made in 18K yellow gold, 18K white gold, 14K rose gold or platinum. We do not offer 18K rose gold because it is less durable than 14K rose gold, and we strive to provide only the best quality. If you need help deciding which option is right for you, contact one of our 12FIFTEEN Consultants.

The Forever Companies Initiative
What does it mean to be a Forever Company?
Forever Companies consists of three different companies: Diamond Nexus, Forever Artisans and 12FIFTEEN. All three companies offer only the best man made products because we don’t want anyone to buy a mined stone. Not a diamond. Not a ruby, emerald or sapphire. There are manmade stones that match or exceed every quality of their mined counterparts. We have partnered with our sister companies to ensure there are options for everyone to find the right jewelry with the right manmade stone. For us, it’s a matter of conscience.
Can I purchase from more than one Forever Company?
Our three companies are connected. That means when you join the Forever Family, you get benefits. You’ll get benefits like VIP sales, first looks and quantity discounts. For information on specifics of our trade-up policies, give us a call.
