Mini FAQ

Yes. Lab-grown diamonds have the same chemical composition and crystal structure as natural diamonds and are also tested as diamonds. The only difference is their origin: they are grown in a controlled environment.

Lab-grown diamonds are typically considerably more affordable than comparable natural diamonds. Just like with natural diamonds, the price is determined by the 4Cs (carat, cut, color, clarity). This means you can often choose a larger or better-cut stone within the same budget.

Yes. There are reputable laboratories (such as GIA and IGI) that certify lab-grown diamonds with an independent assessment of the 4Cs. The certificate clearly states that it is a lab-grown diamond.

The origin is transparent: the diamond is lab-grown. The environmental impact depends primarily on the energy source and processes used; more and more manufacturers are working (partly) with renewable energy. We communicate openly about specifications and certification, so you can make an informed choice.

Jewelry has practical and emotional value; resale value can vary, and the lab-grown market is still developing. Therefore, buy primarily based on quality, design, and the joy of wearing. Not (only) as an investment. With us, you pay a fair, transparent price.

Start with the cut, as this determines the brilliance. Next, choose a carat weight that fits both your budget and the jewelry piece. Aim for a color in the near-colorless range and a clarity that is eye-clean, meaning inclusions are not visible to the naked eye. This way, you achieve the most beautiful look within your budget.

Clean regularly with lukewarm water and a drop of mild soap, brush gently with a soft toothbrush, and dry with a lint-free cloth. Avoid harsh cleaning agents and store your jewelry separately. Have settings checked periodically to prevent loss.
