What our customers say

I am absolutely obsessed with my wedding ring. Felix could not have been more helpful. He made the ring so it fit perfectly around my engagement ring. He took time and care to take the proper measurements so that it fit perfectly. I tried my ring for the first time at the altar and thankfully it was perfect! Felix was amazing, wonderful customer service and the quality is brilliant. I’m so pleased!

Eleanor

Kamil

Beautiful ring. Well crafted and better than expected 🤗🤗🤗

Kristian

Great communication, beautiful item just as described and seen in the photos.

Vladislav

I am in absolute astonishment by how well those earrings are made. Hinges are tight, the piece feels heavy and not hollowed out to save on weight. Not to mention that this is the most luxurious packaging of jewelry I have ever seen! I can only recommend the earrings and Felix’ jewellery! If in doubt whether to purchase, let this be my recommendation to you :)

Why lab-grown Diamonds?

  • Round cut diamond on a white background

    Identical by science

    Chemically, physically and optically identical to mined diamonds. The only difference is their origin.

  • Conscious luxury

    No mining, transparent origin, a lighter footprint - beauty without compromise.

  • Certified brilliance

    Every stone independently graded and certified by IGI or GIA. You know exactly what you are wearing.
