Yes Tom, I agree! The markings really looked like jade. I hate to admit but I have been doing all my specific gravity tests on my kitchen scale so I really need to invest in a better scale.

On hardness, I see jade is 6-7 and agate is 7 - I just tried glass, and when that didn't scratch, I tried a steel knife from my kitchen and thankfully - no scratch! Not sure what I have on hand to try to go higher - any suggestions?

I have read that there is a margin of error on specific gravity - depending on the makeup of the stone itself - so my best guess it that it's chalcedony that is just a little heavier in water - hence the lower specific gravity. With the SG that low it couldn't possibly be jade I'm thinking.
