I do know about the "blueberries", but I though those were usually found in multiples in close proximity. This sphere seems to be off by its lonesome. Plus, it seems to be a lot bigger and more perfect than the typical "blueberry" though admittedly I'm not sure of the scale in this video.
Researchers at NASA’s Jet Propulsion Laboratory noted the size of Martian blueberries tends to decrease with decreasing latitude.

NASA’s JPL also found that blueberries uncovered by the Rock Abrasion Tool aboard Opportunity were about 4 mm semi-major axis length at Eagle Crater and Endurance crater, about 2.2mm at Vostok, and about 3.0 mm at Naturaliste (crater). Those found in “the plains” were smaller (1-2 mm) than those of Eagle and Endurance craters.
Researchers from the University of Utah have explored the similarities between the blueberries and spherical concretions discovered within “Jurassic Navajo Sandstone” in southern Utah. They have concluded Mars must have had previous ground water activity to form the blueberries. However, they do note the spherules are more spherical in the Martian sample due to the lack of “joints, fractures, faults, or other preferential fluid paths,” unlike the Utah sample. A team of researchers from Japan studied the spherules found in Utah as well as spherules that were later discovered in Mongolia, in the Gobi. They found evidence that the concretions found in these locations are first formed as “spherical calcite concretions” in sandstone. Acidic water rich in iron then dissolve the calcite leaving behind the iron rich (hematite) spherule. This leads to the conclusion that the blueberries may have formed early in Mars’s history when the atmosphere was more dense by the same process.>>

Interesting. Zhurong is the farthest north latitude of all the recent rovers so far, so I guess a big “outcrop” blueberry would make sense here. There’s a great interactive map of all the rover locations here:
