I was going to answer here How do I make an object look wet? as it does not specify the rendering engine, but it was closed...
I created a UV Sphere.
Then I used sculpt to make some irregularities to let it shine.
There is 2 lights above, one to the left, other to the right.
Using Principled BSDF (w/o texture).
at Principled BSDF:
Metallic is not what I want, doesnt look wet anyway.
Changing Specular doesnt help, the shine is not sharp/thin.
