The phrase "accurate approximation of the" is correct and usable in written English.
It can be used when discussing a measurement, estimate, or representation that is close to the true value or concept being referred to.
Example: "The scientist provided an accurate approximation of the temperature changes over the past century."
Alternatives: "precise estimate of the" or "exact representation of the".
