Labgrownlove

Labgrownlove is a German seller centred on lab-grown diamonds, with IGI certificates referenced for its stones, though it keeps a separate natural-diamond collection too. Rings come in 14k and 18k gold in yellow, white and rose, plus platinum, and a ring configurator lets you assemble your own combination of stone and setting. The site presents lab-grown diamonds as the more sustainable choice.

Shipping is free across Europe, and the company also runs both virtual and in-person appointments. Orders are covered by a 30-day return policy with free refunds and free ring resizing, and payment can be split through Klarna or made via PayPal and the usual methods. The site is available in German, English and Spanish.
