"After a friend of mine purchased his time piece with Diamond Source I felt confident to purchase with them. From the minute i entered they treated me with respect and after a week i finally purchased my Vacheron Constantin Patrimony brand new 2021. They took their time to make sure i was happy with the fit and setting up the watch. I will confidently make all my jewelry purchases with them! Whether your a first time buyer or collector they are the place to go!"
