Custom Lab-Grown Diamond Jewelry


At Estrell, we create custom lab-grown diamond jewelry designed entirely from scratch—crafted in Switzerland and perfected with Belgian craftsmanship.

As a family-owned brand, we go beyond traditional e-commerce by offering deeply personal, made-to-order pieces: from bespoke engagement rings and bridal matching sets to diamond bracelets, letter necklaces, and memorial diamonds made from ashes, hair, fabric, or even handwritten notes. With full control over your diamond’s cut, color, clarity, and carat weight, your vision becomes a lasting treasure—uniquely yours.

Estrell is a partner in moments that matter—offering heartfelt, high-touch service and one-of-a-kind pieces made not for the masses, but for the meaning.
