No, there's kind of no need, you can pretty much tell by looking at the wire core thickness itself. If you wanted, you could use small lengths of know gauge wire with one end stripped for comparison.

Keep in mind the wire cover thickness varies greatly, and total diameter really can't be used to judge the wire gauge.

Also, 'cheap' wire uses a lower grade or coated cores (higher resistance, easier corrosion), and they don't always meet the standards for the gauge of wire they advertise on the package. Which is why they don't mark the wire cover with the gauge.
