Fleeting moments • lasting memories

We want your jewellery to last a lifetime. Just like the memories it represents.

A ring captures fleeting moments and transforms them into lasting memories – it's a powerful talisman that, with a single glance or touch, sends a jolt straight to the heart.

Our Tender Loving Care promise ensures that your ring will become a treasured family heirloom, passed from generation to generation. At Brown & Newirth we have been designing and creating the finest wedding, engagement rings and jewellery in our North London workshop since 1967 and are delighted to provide a lifetime of the best possible care.

Our promise allows you to enjoy a lifetime guarantee and the following complimentary services;

Each Brown & Newirth ring comes with a lifetime guarantee entitling you to the following:

  • One complimentary engraving (see note 1)
  • One complimentary resize (see note 2)
  • Three complimentary refinishes (see note 3)

Simply request the voucher for the service you would like to use and follow the instructions detailed.


  1. Not all rings are suitable for engraving, for example a diamond set full eternity band. If in doubt please discuss with the retailer where you purchased your ring and they can advise
  2. Our complimentary resize covers one size either way (larger or smaller). Any more than one size may incur a supplementary charge depending upon the style of ring. Any charge would simply be to cover the additional precious metal and craftsmanship. Resizing excludes full set diamond bands. Please note that resizing patterned rings can result in a loss of continuity of pattern around the ring.
  3. A refinish is a suite of processes we use to return your ring, as close as possible to its original condition, including polishing by hand, ultrasonic cleaning, rhodium plating (if white gold) and re-securing stones.

* We promise to respect your privacy and we will not give out your details to any third party. Please see our privacy policy for more information.
