Tiffany & Cartier Engagement Rings

All our Tiffany & Co. Diamond Engagement Rings are expertly authenticated by our DGA-qualified team and include original certification, Tiffany & Co. boxes, and often the original owner’s paperwork. Guaranteed authentic for life, only Bloomsbury Manor offer this expertise and assurance.

Sold with our Proposal-Ready™ promise, every ring is fully serviced, and polished to perfection. Each one is as pristine as the day it was first sold. We offer complimentary, invisible re-sizing and fully insured overnight shipping across the UK and internationally.

A pre-owned Tiffany & Co. ring brings all the prestige and luxury of new — at savings of, typically, 40–60%. It’s a smart choice for your future and the planet. We know a decision to buy a ring like this can be as emotional as it is significant, and we’re here to help you make a choice that’s truly right.
