Really great experience, I wanted a bracelet made and a Leiser and Co offered the best quality for my budget out of many others I spoke to. Highly recommended!

Absolutely great, friendly and professional service!

They were so friendly and professional, took the time to listen and gave me a very good price. I honestly will go back to this jeweller as it was a very good experience and can’t fault them. I tend to feel rushed when I’m normally jewellery shopping or selling so this was a very good experience! Thank you :)
