John,

I'd have never guessed it, but I guess mine is aqua also. Mine looks to be a black chip with lot's of discoloration and fading. Almost as if it had had a chemical spilled on it. After reading your note I took a knife and scraped the edge of the chip and sure enough, after removing a layer of gunk the chip is an aqua color.

Closer inspection of the chip now makes me believe it was involved in a fire. I can see where another chip lay partially over this one causing a semi-circle pattern which kept part of the chip from turning completely black.

Kind of makes me wonder if it was an illegal club somewhere that burned down?
