Calling all Fashion Mavens -- need "good taste" advice!?

You could buy a diamond necklace to match the earrings! Or if you cant afford it try getting a necklace that is silver or you could buy a silver necklace!

You could do a silver necklace from Tiffany- If you have that money to spend.
Do something silver that compliments the earrings without distracting the attention away from the dress.

Try wearing something with the color metal of the earrings. If they're silver, wear a silver necklace of sorts, or if they're gold, wear some type of gold necklace. Technically, you could even wear something with another color in the necklace since you're only wearing black silk and diamonds. Maybe if you had time to go shopping, you could find a fake diamond necklace that you like. Cubic zirconia and diamonds look pretty much the same, so I'm sure no one would be able to tell, and then you would have something for future need. If worse comes to worse, ask for your husbands or a friends advice as to whether or not your outfit looks to severe without the necklace, and if they say no, then I'm sure you'll look great!!
