The Champagne Diamond Surprise

Engaging Group Experience

Every guest receives a glass of champagne. In each glass, we have placed a real diamond or a cubic zircon (an imitation diamond). Nobody can see the difference between a real diamond and the zirconia. That's why we have one of our master polishers with a diamond loupe to check each stone. He or she determines which stones are imitations and which are real. Of course, only a few (or one) of the stones are real diamonds. But the guests can also keep the zirconia as a beautiful memento of the entire evening. While the diamond polisher checks the diamond, he or she explains a bit about the process of recognizing a real or a fake diamond. If people have questions about their own jewelry, they will be answered in a discreet and fun manner.

This event can be held at our premises or any other venue of your choosing.
