I’ve created a Google Maps JavaScript embed with a RichMarker placed at the arbitrary coordinate 50.85, 4.35. I’ve marked this coordinate by approximation with a green dot in the screenshot below.

As you can see, the content of the marker is placed above the coordinate. This is not the behavior I’m looking for. Instead, I want the marker to be centered over the coordinate, as shown here:

Is there an easy way to enforce this type of placement using the standard Google Maps API, a plugin or jQuery? I’m using v3 of the API.
You need to set the anchor for the RichMarker to be the center of the image (not the bottom center).
