The Imperial eye
Not merely perfect.
Impossible to forget.
For nearly five decades, our family has sought diamonds with a presence beyond their certificate: historic cuts, remarkable colour and the singular beauty that makes a stone unmistakably its own.
Antique diamonds
Cut by hand.
Alive with history.
Old mine cushions are prized for generous facets, distinctive proportions and the warm, intimate light of another era. Each is selected individually for its personality.
