Natural Diamond Jewellery

Discover our collection of natural diamond jewellery: necklaces, bracelets and earrings handcrafted in our workshop in Antwerp. Available in 18K white, yellow or rose gold, or platinum, each Beldiamond creation can be personalised to suit your style. Formed naturally deep within the Earth over billions of years, every diamond has its own unique characteristics and individuality. Each natural diamond of 0.30 ct or above comes with its own GIA certificate.

Natural diamond necklaces, bracelets and earrings

Discover our four-prong and bezel-set pendants, halo designs, tennis necklaces, as well as a selection of natural diamond earrings and bracelets. Our earrings are available in various styles, including four-prong settings, bezel settings and small huggie-style hoops. Our tennis bracelets are available in different lengths and diamond sizes, including diamonds in F colour and SI or VS clarity.

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

GIA-certified natural diamonds from 0.30 ct per stone

Every natural diamond is unique in its origin and characteristics. At Beldiamond, each natural diamond of 0.30 ct or above comes with its own GIA certificate.

This independent gemmological certificate details the main characteristics of the stone, including its 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 diamonds comes with two GIA certificates.

How to choose your natural diamond jewellery

Your choice will depend on the type of jewellery, the metal, the size of the diamonds and your budget. To help you compare stones, our experts explain the four main diamond quality criteria, known as the “4Cs”: carat weight, colour, clarity and cut.

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

Our experts help you find the right balance between quality, proportions and budget, while preserving the unique character of a natural diamond.
