They are even lovelier in person and I look forward to wearing them for decades to come. Andrew and Gemma provided excellent communication and prompt dispatch.

Excellent customer care.
Excellent customer care.
I had to place the order over the phone as my internet was misbehaving. The lady who I spoke to could not have been more helpful and was particularly careful to get all the details correct. I was then informed about the collection and dispatch of the item purchased, by email. The item arrived as expected and it had been most well packed so that no harm could come to it. It was a delight to purchase this item from C6323, AC Silver, and I could not fault any aspect of their customer care. I was highly delighted with my silver mustard pot and it was much better than the pictures on the web site.
