Lightbox Jewelry - Frequently Asked Questions

Are Lightbox diamonds real diamonds?

Lightbox's diamonds are lab-grown diamonds that exhibit the same chemical makeup of real diamonds. However, because they're grown in a lab rather than naturally, they are not considered real diamonds. Still, they look and behave much like a real diamond does.

How does Lightbox Jewelry make its lab-grown diamonds?

Lightbox Jewelry uses innovative technology to create its lab-grown diamonds that look like natural diamonds. Using lab-created diamond "seeds," Lightbox uses a plasma reactor to grow diamonds much quicker than they'd grow naturally in the environment.

What are the differences between Lightbox's carats?

Lightbox offers varying degrees of diamond quality, which it categorizes by Lightbox Finest, Lightbox Finest Loose, Lightbox, and Lightbox Loose — with Lightbox Finest being the best quality and Lightbox Loose being the most affordable. Carats vary in weight from 1/10th of a carat to 2.10 carats.

How should I care for my Lightbox Jewelry diamonds?

Lightbox Jewelry recommends storing your diamonds and jewelry in cushioned containers to avoid scratches and damage. Also, clean lab-grown diamonds regularly with a soft cloth and a mild dish soap diluted with water.
