Even better than the renders made it look and my fiancée loved it!

I had my fiancée's ring customised and the process with my designer was sublime! Nothing was too much and I was provided with renders at every step of the way.

Excellent service, and honest advice. Thanks so much!

My experience of getting an engagement ring here was very good. The staff at the office were so helpful (especially given I turned up not knowing I should've booked an appointment). For someone who knew nothing about rings, they made the process of choosing one pretty seamless. If you are looking for a range of designs that you can then customize, I would highly recommend them. The main benefit has been the aftersales service. All through the production and delivery, they kept me up to date, and when we had a small issue shortly after delivery, they were very quick to rectify the issue and cover the cost. When you are spending on a higher-value item like this, I think this type of aftersales support is invaluable. P.S My fiancé said yes, so I assume she would also give 5 stars.

My experience with Taylor & Hart has been absolutely fantastic from start to finish. Aurélie brought us up to speed on everything we needed to know, and went above and beyond to ensure the ring was delivered on time and the diamond was up to their high standards. The communication was perfect from start to finish.

I had a great experience ordering from Taylor & Hart. A big thanks to Pedro who helped in the design. Couldn’t recommend enough.
