The Schaffhausen manufactory is still full of surprises 150 years after it was founded. A specialist in exclusive models, it admirably combines classicism and modernity, as shown by the solitaire in its Les Essentiels collection. A diamond is a symbol of sensuousness and eternity. This solitaire is offered in a minimalist or opulent fashion, depending on the particular wishes of the couple ready to tie the knot forever.
