Technology jewellery maker Vinaya, formerly known as Kovert Designs, has raised $3m (£1.9m) from a host of investors.
The brand has backing from venture capital firms Passion Capital and Playfair Capital. Other shareholders include Michael Birch, who founded the social network Bebo, and Robin Klein, an investor who backed LoveFilm and Zoopla.
Vinaya manufactures modular jewellery called Altruis, which features a bluetooth-enabled zirconia ceramic stone that produces alert vibrations for texts, emails or calls based on pre-set profiles.
The business was founded in 2013 by former model and technology consultant Kate Unsworth. It launched its first collection on its own ecommerce site last year. It is also stocked on Net-a-Porter.
Altruis stones retail alone for £110, while complete jewellery such as bracelets, necklaces and rings start from £290. Additional pieces without stones range from £180.
