Experiencing the world of gemstones means experiencing the world of Constantin Wild … welcome! At Hauptstrasse 103, the myth of gems comes alive in the truest sense. In the cellar of rough stones, the rarest unprocessed stones from the most remote places in the world are waiting to unfold their beauty – which they do at the cutting workshop, under the hands of our artisans. With dedication, masterful skill and patience, they unveil the coloured splendour hiding inside the plain shell. Some of the finest gems delight the eye in the Gem Room, the in-house presentation room, while the jewels that are currently most exclusive are kept in the treasure chamber. The journey of discovery ends at the Gem Bar, in serenity and calm.
