After completing her Masters degree in Mechanical Engineering it was the technicality of the gemstone world, along with being able to work with people enjoying their most special moments that has made starting Diamondology her ideal calling. Since then she has started Jersey Silver Jewellery with beautiful collections made from our iconic Jersey Granite.

'My philosophy is that anyone can now go and buy jewellery, but what makes your piece special, unique and the perfect symbol of love and commitment? Diamondology was founded on experience and service as well as expert advice to ensure your jewellery is as unique as you are. Jersey Silver was founded on the same belief putting a unique twist into something you can give, buy and wear everyday.'
