She said YES!
Alexandre made the most beautiful ring for the engagement of my now fiancée and me, based on two rings from my grandmother. Alexandre takes the time to understand the clients wish and uses his expertise to propose different options. In the end the ring ended up looking fabulous!
Excellent quality and communication

THE BEST JEWELLER EVER!!!
I have been looking for a precise piece of jewellery with a diamond for several years and I was lucky enough to finally find Alexandre Rosenberg’s products online. The service they provide is immaculate and the craftsmanship is at a high level. To be honest I was sceptical enough to order gemstones online, however based on the initial email from the company I realised that my order is in hands of professionals. Further they answer all your questions via whatsapp swiftly. All gems are GIA certified and a certificate is provided as well. I decided to start with a relatively small order just to try them in terms of quality and timing. The price they offered was surprisingly handsome and on top they upgraded my gem stone (characteristics wise) for free in the end. On top as a matter of practice they offer a 3 month equal instalment payment option in case you would like not to pay the full amount in advance. They send the item as soon as has been produced via secure delivery service - Fedex, however, next time I will probably opt to travel to Luxembourg to pick it up myself as in this case they provide a refund of VAT. Many thanks guys I just love my new baby. Xx
Exquisite!
I have ordered multiple times and everything has always been superb. Thank You! Will be ordering again and again.
The most amazing jewellery!!!
Today I have received a divine black diamond platinum ring from Alexandre Rosenberg. I feel this is the beginning of a beautiful friendship in terms of my future jewellery choices. I am already looking forward to my next order. I am glad to have found a great professional and a lovely person who had the patience to answer all of my questions, and who chose the best stone for my ring size. I am truly grateful for your input. Thank you very, very much!
Amazing artwork and exceptional service

Excellent service
Excellent service. I ordered a custom engagement ring with special requirements on the gemstone. Alexander offered a great selection of gemstones with very transparent options and pricing. Further he supported with very good advice and fast communication. The result was a breathtaking engagemenet ring that far exceeded my expectations. Will definetely be back for the wedding rings.
Amazing in all respects
I wrote a review in October regarding a ring I had custom made. I made a mistake, Alexandre went above and beyond to help me rectify the problem I had created. He was flexible and generous in the solutions he offered which, I believe, would not have been possible if I had purchased from the high street. I now have a beautiful ring, perfect for me. This guy is amazing and so are the pieces he creates.
Perfect custom Pieces from a trusted jeweler
We have gone here for our engagement ring, wedding bands, and most recently for a custom piece. This work is unparalleled - his attention to detail and care he puts in all his work is truly remarkable -- each piece is unique and beautiful. We will continue returning - simply put, the best jeweler.
The best diamands at the best price.
Quality jewelry and service
I was searching for a unique pendant and was immediately impressed by Alexandre’s quality and user-friendly website, which was complemented with his prompt and accommodating responses to my questions. He recommended a gemstone that corresponded perfectly to what I wanted and took the care to follow through until the end on providing a quality customer experience. The pendant is gorgeous and I would not hesitate to order another piece from Alexandre.
Very responsive and helpful
Very responsive and helpful. We bought wedding and engagement rings and are very happy with the quality.
