I could not have asked for a better experience while ring shopping with Len and Amy. They took plenty of time to explain the different styles of rings and answer all of my questions. They were quite patient and helpful with selecting the perfect ring for my fiancé. Their fantastic customer service and the ring was more stunning than I ever imagined. I will be recommending them to everyone.

I went to Len with a custom engagement ring design. After meeting with him just once, we nailed down the exact design and he and his team got to work. Within 6 weeks, he had created a masterpiece that my fiancé now wears proudly on her finger. The ring is absolutely one of a kind and the service provided by Le Joaillier has made me a customer for life!
