Beverly,

    I have had good luck polishing Covellite with Alumina (Linde A) on a
    dampened piece of cushioned felt. Make sure you use real felt, the
    wool kind, not the nylon "felt" commonly sold at the fabric stores. A
    very slight amount of alumina will do the trick. You might also try
    one of the "Miracle Fiber" absorbent cloths, either dry or dampened
    with a little alumina. The discoloration is just an oxidation product
    and is normal over time, especially if you live in or near a large
    city with acids in the air, as Covellite is just CuS. If you don't
    have or can't get the materials to do this, I'll polish it for you
    for free if you pay the postage. 

Good luck,
Wayne
