Aluminium and silver on natural gut.

Pros: As with the A string, wonderful gut sound and fairly easy to play. Easy under the fingers.
Cons: If you're new to gut they will take some getting used to. The lower tension means they tend to "roll" under the fingers and can sometimes feel a bit soft under the bow. Definitely slower to respond, and you have to adjust your bow technique to compensate (Which is for the better, after playing on these I sound a lot better on steel)

Pros: Not as brash and squeeky as an uncovered gut D string, but works very well with a pure gut A string which is my preference - this is a beautiful combination. Smooth, rich and expressive.
