The jeweler “Diagen Diamond” is beautiful and of good quality. The staff are both friendly and experienced.

We were looking for rings etc. for our upcoming wedding. After checking out several stores, we went to Diagen and I can say in advance that we did all of our shopping here. The staff and service, particularly from Ibrahim, was extremely courteous and professional. The rings we ordered even exceeded our expectations. This made Diagen our trusted jeweler. Great from start to finish, so we could say “finally” and be our first port of call at all times.

It has friendly and warm-hearted staff who care deeply about customer satisfaction. A decent jewelry store with a wide range of products. THANK YOU for your interest, DİAGEN employees.

Lots of selection of modern gold jewelry, something for every taste. Excellent advice, transparent prices. I dropped off a ring and a chain for repair, it was quickly professionally repaired on the same day, it's definitely worth a visit. It won't be the first visit, definitely recommended.

Sehr freundliche Bedienung und fairer Goldpreis. Auf der gesamten Keupstraße der beste Laden, wirklich zu empfehlen! (Translated by Google) Very friendly service and fair gold price. The best shop on the entire Keupstraße, really recommendable!

A ring for 100€ that is completely bent after wearing it for the second time. Very poor quality/Not good value for money. Not recommendable.

Good service. I have already ordered 3-4 times and have always been satisfied. Shipping is also super fast, although the goods still need to be adjusted to the dimensions. Always my pleasure :)

Schönes Sortiment, schöner Laden (der schönste auf der Straße) und extrem freundliche Mitarbeiter. Lohnt sich vor allem für Verlobungsringe!

Hakan Bey ve çalışma arkadaşlarına çok teşekkür ederiz, her gitmemizde gereken ilgi alâkayı fazlası ile gösteriyor ve memnun ayrılıyoruz, her daim tavsiye edebileceğim bir Kuyumcu İşletmesi 👌

Hab online bestellt um 9.2.2023 und bis heute dem 20.2.2023 den Schmuck nicht erhalten obwohl eine Lieferzeit von 2-5 Tagen angenommen wurde auf meine Kontakt Anfrage und meine anderen Versuche Kontakt auf zunehmen wird nicht reagiert also nicht zu empfehlen

Sehr freundliches und Kompetentes Personal. Eines breites Sortiment, lässt keine Wünsche offen. Würde ich jedem weiterempfehlen!

I was there last week and loved it. I was welcomed and advised very politely. Time was taken to clarify questions. I can definitely recommend it and will always buy my jewelry there in the future. Thanks again to the nice team.

I bought a bracelet for my niece here. Can only recommend the store. The gentlemen are very friendly and try to please everyone.

Assalamu Alaikum Hello, The most beautiful money changer's shop I have ever visited. A place that makes you say 🌟This is it!🌟. Both the service, the variety and the designed products are extraordinary... I wish you continued success and good luck. 💐 Selma A.

Very good service. I ordered for the first time last week, the goods were shipped on Monday and I received them on Wednesday. I always got very quick answers to my questions on Instagram. I can only recommend. Always my pleasure :)
