Monica Vinader launches first trademarked diamond cut in Siren collection

Monica Vinader has turned its Siren shape into something more defined, and more defensible: the brand’s first original, trademarked diamond cut. Developed over two years, the MV Siren Diamond Collection positions the hero ring as a contemporary alternative to the traditional solitaire, while also marking Monica Vinader’s first formal step into bridal and engagement jewellery.

For shoppers, the immediate difference is visual rather than theoretical. The MV Siren Diamond uses the brand’s asymmetric Siren silhouette and 64 precision-cut facets, a configuration designed to maximise brilliance while giving the stone a recognisable outline of its own. That matters because a standard solitaire usually relies on the setting and the quality of the centre stone for distinction; Monica Vinader is trying to build identity into the cut itself. The result is less about inventing a new diamond and more about branding the diamond’s face, shape, and light return in a way customers can recognise at a glance.

The hero MV Siren Diamond Ring comes in one-carat and half-carat sizes, with earrings, a necklace and a bracelet extending the line beyond bridal. That broader assortment suggests Monica Vinader is not treating the collection as a one-off engagement play, but as a signature language the brand can carry across categories. For a company founded in 2008 and long associated with responsible jewellery, that is a meaningful expansion.

The sustainability pitch is central to the story. Monica Vinader said the diamonds are lab-grown using 100% renewable energy and hand-set in 100% recycled gold. Each stone is independently certified by the International Gemological Institute and sourced from producers accredited under the SCS-007 sustainability standard. The brand’s Product Passport programme, launched in 2022 with Ennovie, now covers 70% of its styles and is designed to trace a piece from sketch and sourcing through creation to the customer.

The key consumer question is whether this is real innovation or smart branding dressed up as gemology. The answer is both, but not in equal measure. The cut itself is a genuine product distinction because it creates a proprietary silhouette and a branded point of difference in a crowded diamond market. Yet the emotional and commercial power of the launch lies in how Monica Vinader packages that cut: as traceable, lab-grown, and bridal-ready. In practical terms, the customer is paying for a signature look and a clear provenance story, not a revolutionary new form of sparkle.
