Customer Reviews
Reliable for engagement rings
This is my third purchase from British Diamond Company, actually. I got a sapphire engagement ring this time, and like my previous orders, the delivery was quick and the item was exactly as described. Their ethical sourcing is a big deal to me, and they've always been consistent with that. Their support team was helpful when I had a question about sizing, too. Always a smooth experience.
Good quality, delivery a bit slow
I ordered a pair of diamond stud earrings. The ordering process on the site was straightforward and easy to navigate. Quality-wise, the earrings are beautiful and sparkle really nicely; they feel substantial. Delivery took about 8 days to reach me in California, which was a little longer than I hoped, but they were well-packaged and arrived securely. I had a quick question about cleaning the diamonds when they arrived, and customer support got back to me within a day with useful info. Overall, a solid purchase, just allow a bit of extra time for international shipping.
Love my new Whitby Jet!
Just received my Whitby Jet necklace and it's absolutely gorgeous! The quality is superb, and it arrived super fast. I'm so happy with it. Definitely shopping here again and telling everyone!

Thinking of getting an engagement ring here. Does anyone know if they do interest-free finance? And can I still use a discount code with that if they do?
hey, was looking at some of their rings, thinking about getting one for my girlfriend. just wondering if their diamonds are actually legit ethical or if that's just marketing speak?
