I gave my wife a heart-shaped diamond on our wedding anniversary. I always appreciated the comprehensive advice and did not miss the face-to-face personal contact I would have had in a conventional store. My wife is also delighted.

She said "I do" on the roof of Milan Cathedral. Thanks to all the RenéSim team for the excellent advice and rapid service!!

Erik P., Ulm

The ring arrived safely today; it's absolutely beautiful. Many thanks, particularly for the discreet correspondence and reliable delivery.
