Frequently Asked Questions

How is your jewelry so affordable?

At EX3 Diamond, we use recycled metals and lab-grown diamonds to cut costs and ensure environmentally-friendly production. We also manufacture everything in the United States to eliminate middlemen and bring you lower prices.

How does carat weight work for earrings and pieces with multiple stones?

The total carat weight we list includes all the stones for a particular piece, including both earrings.

Are lab-grown stones really the same as natural diamonds?

Natural diamonds are produced through a combination of heat and pressure on carbon. With our sophisticated machinery, we can imitate this process in a fraction of the time, producing brilliant diamonds in days instead of centuries. Once complete, our lab-grown diamonds are the same as natural diamonds – down to the last atom.

The only way in which our diamonds differ from those found in the Earth’s crust is that ours are conflict-free and environmentally friendly!

Is it safe to buy diamonds over the internet?

Absolutely. When you shop EX3 Diamond, you get multiple levels of security to ensure your transaction. First, we use Digicert and secure socket layer encryption to protect your personal information. We also send all orders through insured mail to protect your package until its arrival. Lastly, you get a certificate stating that diamonds have been tested and examined by the IGI (International Gemological Institute).

Is mailing diamonds safe?

Of course! We insure all packages and require a signature upon delivery. Each package is sent directly to the confirmed address, and we take full responsibility for the jewelry within until it's been signed for.

Will the jewelry I receive be exactly what’s listed on the product page?

We do our best to recreate each style you see in the pictures, but there will be some variation from piece to piece. Because we use genuine materials, stone quality, diamond specifications, and gram weight could vary slightly.

What if I can’t find the perfect piece I want on your site?

At EX3 Diamond, we offer custom jewelry creations. If you have a vision in mind, please share it with our professional designers for a one-of-a-kind piece. Start customizing here!
