Aren’t all diamonds brilliant?

Not at all! Here is a comparison between a standard diamond and an excellent diamond, with high Brilliance, Fire & Sparkle. Only 1 in a thousand diamonds can achieve this level of brilliance.

What are the Dual Certificates?

We are able to guarantee the diamonds’ exceptional quality and superior brilliance by using a combination of two different diamond certificates:

1. Triple Excellent cut, graded by GIA.
2. Guaranteed High Brilliance, Fire & Sparkle, certified by GemEx.

100% money back guarantee if your LUMOS by ZCOVA Diamond does not meet the requirements.
