Talk to a jeweler, not a chatbot
Questions about a piece, a resize, a valuation or a shipment? Write to us and a member of our own team answers, usually within one business day. Our workshop hours are Central European Time, and we keep late afternoon and evening slots open so they land in the American morning and afternoon.
Include the piece reference if you are writing about something specific, and we will send extra photographs the same day.
Private video viewing
The fastest way to get a real answer. Pick a slot in your own time zone and we will show you the piece in daylight.
