I have dealt with AC silver on several occasions

I have dealt with AC silver on several occasions and always found Andrew extremely knowledgable and trustworthy. Nothing is too much trouble and I am absolutely delighted with my last purchase of a 5 stone diamond ring. From start to finish the process was extremely easy and everything catered for. It was a pleasure to del with Andrew and his most helpful and charming Assistant.

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.
