Customer Reviews
Love my new watch!
I just received my new Tissot watch and I absolutely love it! The packaging was so elegant, and the watch itself is even more stunning than I expected. The detail is incredible. I'm so glad I decided to splurge a little. It arrived quickly too. Fantastic experience from start to finish!
Good Whitby Jet necklace
Ordered a Whitby Jet necklace. Arrived on time. Quality was good. No issues. Would buy again.
Nice sapphire ring, quick ship
I got a sapphire engagement ring from them last month. It was super pretty in person, even better than the pictures online. Shipping was really fast too, it got here in like 3 days, which was a nice surprise. No complaints, the whole thing was pretty smooth sailing.
Good value on wedding band
I needed a men's wedding ring and looked around quite a bit. Found a good deal on a classic gold band here during a sale. I signed up for the newsletter and got a small extra discount, which was a bonus. The price felt very fair for the quality, and it arrived well-packaged. Definitely felt like I got good value for my money compared to some other places I checked out.
Consistent quality, reliable service
This isn't my first time buying from British Diamond Company. I've bought a few pieces over the years, including a pair of Blue John earrings last year. This time, I got a silver tennis bracelet. The quality is always consistent, and the descriptions online are accurate. Shipping is reliable, usually takes about 4-5 business days to get to me in Texas. It's why I keep coming back; I know what to expect and they deliver.
Lovely earrings, slow customer service
I purchased a pair of diamond stud earrings and they are absolutely beautiful, really well-made. The free delivery was a definite plus. However, I had a question about resizing after they arrived, and it took about two days to get a response from customer service, which felt a bit slow. Not a deal-breaker, but it could be quicker. Overall, I'm happy with the quality and the product itself, just a minor hiccup on the communication.
British Diamond Company Community Discussion
Share tips, ask questions & help fellow shoppers save more
I'm in NYC, how long would it usually take for a diamond necklace to get to me if I order from them? Their site only talks about UK delivery.
Hey, does British Diamond Company do interest-free finance? Looking at a watch but my wallet is crying.
Found a 10% off code online, but it won't apply to the Bremont watch I want. Anyone know if certain brands are excluded from discounts?
Thinking of getting an engagement ring here. Does anyone know if their diamonds are actually legit ethically sourced like they claim?
Is their Whitby Jet jewelry actually real, or is it just 'jet-like' material? Don't want to get scammed.
