Field notes
The visible atlas distinguishes catalogue illustrations from member-owned slabs and displays counts rather than public listings or prices. For verification, owners are asked for a grader, certification number, and a photo containing a one-time code; the site says location and camera data are removed from photos. Its stated transaction sequence uses binding offers, concierge contact, and arranged insured shipping, with payment going directly to the seller or through a regulated partner.
