Your Personal Jeweller

Goldsmith Katie is a gold member of the Goldsmiths Company (one of the twelve great livery companies of London which dates back to 1300). Often referred to as 'sparkly' Katie studied for her Ba (Hons) Jewellery Degree in London where she fell head over heels in love with the dazzling world of jewellery. From the glittering history books and glossy fashion magazines she devoured in the library to the practical lessons at the bench. It's here where Katie's passion and excitement for jewellery bloomed.

After cutting her teeth within the luxury jewellery industry for legendary giants, Tiffany and Co, Pomellato and Carolina Bucci. Her personal fashion jewellery collections proved successful and she naturally gravitated towards the world of fine jewellery founding Crux in 2014.

Katie injects her passion and love for jewellery into every make and bespoke journey. It's the little things, moments and celebrations that make life exciting and precious. Like the gems created in her workshop.


Responsible Materials

At Crux we only use the finest materials to produce our jewellery. Solid 9ct / 18ct Gold and Platinum. Our jewellery is produced using recycled grain which reduces the demand for mining these precious metals.

All of our bespoke jewellery is cast, set and hand finished by artisan craftspeople in Hatton Garden, London. Only our chains and huggie components are sourced from Italy.

We have long-standing relationships with our gemstone and diamond suppliers ensuring our stones are ethically sourced and conflict free.

Every stone is hand picked by Katie and chosen for its ethics and natural beauty.

Engagement ring of dreams. You made the process seamless and the aftercare has been incredible too.


It took my breath away, it's a sparkly piece of perfection and I can't wait until Hannah is wearing it.


Thank you so much!! The earrings look absolutely fabulous - I couldn’t be happier with them. They are even better than I’d hoped for!


It was such an instant connection from the moment we met you at the studio. It's so clear how much joy you get from your work and how much love you put into the rings.

Bespoke Timeline

Hatton Garden

Hatton Garden’s association with the jewellery trade dates back to Medieval London, when particular crafts and industries clustered around specific neighbourhoods to ease production and trade. Hatton Garden is still London's prestigious jewellery hub and the proud home of Crux.
