Room darkening window curtain rod assemblies that include a curtain rod and two bracket assemblies, each including a removable magnetic finial are disclosed. Each bracket assembly includes a wraparound leg that extends perpendicularly from an axis of the curtain rod toward a wall or window frame upon which the assembly is installed. The removable finials allow a curtain to be drawn onto the wraparound leg of each bracket assembly from the curtain rod to provide curtain wraparound regions. The curtain wraparound regions reduce or prevent light from entering into a room, and allow the bracket assemblies to be hidden. Once the curtain is extended into the wraparound regions, the magnetic finials are magnetically attached to the bracket assemblies with portions of the curtain located therebetween.

A curtain rod apparatus includes a curtain rod having opposite ends. Each end can include a finial attachment mechanism. Each finial attachment mechanism can include at least one magnetic elopement of a finial attachment assembly positionable within the curtain rod that can be configured to facilitate attachment of a finial to the end of the curtain rod. In some embodiments, the assembly for each finial attachment mechanism can be configured so that no tools are needed beyond use of a user's hands to attach finials to the ends of the curtain rod.
