Our Quality Promise

Being the South West’s leading independent jewellery and watch retailer, we have a responsibility to you, our customer, to ensure that you are getting a leading, luxury service.

We only offer you ethically sourced 100% natural, untreated diamonds. All of our diamonds have been purchased from legitimate sources, not involved in funding conflict, in compliance with United Nations Resolutions and the ideals of Kimberly Process. Michael Spiers guarantee our diamonds are conflict free, based on personal knowledge and/or written guarantees provided by the suppliers of these diamonds.

Certified diamonds will only come from the Gemological Institute of America (GIA), HRD (Antwerp) or IGI (Antwerp) as we feel that these are the only labs worldwide that reflect our high standards.

We are a family business and aim to give all our customers the benefit of the experience we have built up over generations. 

Explore our Engagement Rings and Wedding Rings with ethically sourced 100% natural, untreated diamonds.
