Lab Grown Diamond Jewellery

Discover our collection of lab-grown diamond jewellery: necklaces, bracelets and earrings handcrafted in our workshop in Antwerp. Lab-grown diamonds, also referred to as synthetic diamonds, are real diamonds with the same chemical, physical and optical properties as natural diamonds. Available in 18K white, yellow or rose gold, or platinum, each Beldiamond creation can be personalised to suit your style. Each lab-grown diamond of 0.30 ct or above comes with its own IGI certificate.

Lab-grown diamond necklaces, bracelets and earrings

Discover our four-prong and bezel-set pendants, halo designs, tennis necklaces, as well as a selection of lab-grown diamond earrings and bracelets. Our earrings are available in several styles, including four-prong settings, bezel settings and small huggie-style hoops. Our tennis bracelets are available in different lengths and diamond sizes, including lab-grown diamonds in E colour and VVS clarity.

These creations represent only part of our collection. Many other designs can be personalised by choosing the metal, diamond size, proportions and setting. You can also create a fully bespoke piece of jewellery based on your own inspiration.

IGI-certified lab-grown diamonds from 0.30 ct per stone

At Beldiamond, each lab-grown diamond of 0.30 ct or above comes with its own IGI certificate.

This independent gemmological certificate confirms the laboratory-grown origin of the diamond and details its main characteristics, including carat weight, colour, clarity and cut quality.

The 0.30 ct threshold applies to each individual stone rather than to the total diamond weight of the piece. For example, a pair of earrings set with two 0.30 ct lab-grown diamonds comes with two IGI certificates.

How to choose your lab-grown diamond jewellery

Your choice will depend on the type of jewellery, the metal, the size of the diamonds and your budget. Just like natural diamonds, lab-grown diamonds are assessed according to the four main quality criteria known as the “4Cs”: carat weight, colour, clarity and cut.

Lab-grown diamonds generally make it possible to choose stones with very high quality grades, such as D or E colour and VVS2 clarity, while keeping the budget more accessible. This means you can often choose a larger diamond or opt for higher specifications for the same budget.

The setting also influences the overall appearance of the jewellery. Prongs highlight the shape and brilliance of the diamond, while a bezel setting surrounds the stone with metal for a cleaner, more streamlined look.
