Our sustainability policy

Did you know?

By buying antique, vintage and second hand jewellery you are giving these pieces a second lease of life!
There is a big shift for reusing beautiful objects and items, not just in the fashion world, but also in the jewellery industry. Vintage is no longer just for clothing. We find more shoppers are looking to the craftsmanship of the past for their everyday jewellery.

Made in the UK with a lot of thought and love

Parkin & Gerrish are very proud to be not just a British Brand, but also a small family run business. We have personally hand-picked all our jewellery, as well as our manufactured jewellery, our packaging and even our jewellery cleaner from all over the UK, supporting local and small businesses.

The point is, we know exactly where everything comes from and how it is made. We have homegrown ethics and principles, we care about people, customers, suppliers and our planet and the next generation.
