Courbet

Courbet positions itself at the high end of the lab-grown market: the aesthetic is classic French fine jewellery with the same attention to setting quality and stone presentation you’d expect from a Paris maison, but using exclusively lab-grown diamonds and recycled gold. Responsible Jewellery Council certification adds an independent layer of accountability.

The price point is higher than most lab-grown brands because the product is positioned as fine jewellery first rather than an ethical alternative to diamond rings. Shipping to Switzerland is available. For buyers who want ethical materials without the brand signalling that this choice involved a compromise on elegance, Courbet makes a strong case.
