Beautiful diamond ring at a fantastic price. Very quick turnaround from order to dispatch. Lost one star due to delivery which was meant to be next day guaranteed but instead took 3 days.

Far too many spam emails
Far too many spam emails, without any real value to them, continued miss information. For example about to be delivered, when it had already been delivered. Just expect a bit better here.
Online order.

All that I did not expect after ordering, they kept me informed at every stage of my order from purchase, build and delivery. I will return for another gift for my wife and I have recommended them to friends and family. Well done all round.

No Customer Support or Response
I placed order DFPT782/1 on May 7th and unfortunately the biggest issue so far has been the complete lack of customer support.
The last update I received was on May 14th saying that the selected stone had arrived, but since then there have been no meaningful updates regarding the order status or expected delivery date.
I have tried contacting support multiple times through both the phone number and the website chat, but neither allows you to speak to an actual person — they only allow leaving messages. After 21 days and several messages sent, I still have not received a single reply.
At this point, my concern is not only the delivery timeframe but mainly the complete absence of communication and support for such an important purchase.
I would simply like a proper update regarding my order and a realistic delivery estimate.
Update (1 June 2026):
Today I finally received a response from customer support after 23 days. They explained that a technical issue appears to have prevented my previous messages from reaching their support team, and they have now assigned someone to follow my order directly.

They were amazing the customer service was very good there was a few hiccups but the guys were very helpful and kept in contact with me all the way, I have had so many compliments about my earrings and they do exactly as you ask, I was a little bit skeptical at the beginning but it all turned out amazing. They will be my new go to for Jewellery.

No customer service what so ever
No customer service what so ever. I didn't receive the certificate with my order, and no one replies to messages, emails, chats, phone calls or FB Messenger. Never again 👎
Edit: they only replied after I wrote this review. Wouldn't still recommend.
