Diamants de laboratoire

Lab-grown diamond jewellery, all in one place

From engagement rings and everyday earrings to pendants, bracelets and necklaces, this collection brings together GREMARI jewellery with lab-grown diamonds. Different cuts, carat weights and settings make it possible to choose something discreet or make the diamond the clear focus of the piece.

What is a lab-grown diamond?

A lab-grown diamond is a real diamond created under controlled conditions rather than formed naturally in the earth. It has the same essential physical and optical properties as a natural diamond; the difference is its origin. That means you can compare lab-diamonds in much the same way — by looking at cut, colour, clarity, carat and, ultimately, how the stone looks in the finished jewellery.

Start with the jewellery you want to wear

A solitaire ring puts one diamond at the centre of attention, while earrings and pendants offer an easy way to wear diamonds more regularly. Tennis bracelets and necklaces create a continuous line of brilliance, and designs with smaller stones can bring diamond detail without making the piece feel overly formal.

Shape and size change the character of the stone

Round lab-grown diamonds have a classic, brilliant look, while oval and pear shapes create a more elongated outline. Emerald cuts are cleaner and more architectural, princess cuts bring sharper geometry, and other cuts offer their own proportions and character. Carat matters, but shape and setting can change how large and prominent a diamond appears.

Choose by style, not specifications alone

Diamond grading can help you compare stones, but jewellery is ultimately something you wear rather than a list of numbers. Think about the gold colour, proportions, setting and the way the piece fits into your own style. Those details often make more difference in everyday wear than choosing a stone by carat weight alone.
