The specific gravity varies from 0.988 to 1.279, but the porosity of the mineral may lead to error.

Its specific gravity varies from 1.054 to 1.057.

This certainly doesn't seem to be the case for Earth where gravity varies everywhere.

The specific gravity of bytownite varies between 2.74 and 2.75.

Owing to differences in composition, the specific gravity varies from 4.4 to 6.6 g/cm.

It is certain that the practice lent itself to serious abuses, whose nature and gravity varied at different epochs.

Also, be aware that gravity, pressure, and radiation vary from area to area, according to our needs.

Specific gravity may vary depending on the location and the supplier.
