Black ribbon swirl -- Ravenswood?

[Steph]

Up for ID is a black(ish) swirl with a bright white base.

 

I think the base is not quite as bright and uniform as the CAC at the top of the photo.   I pulled in different marbles -- some for comparing base colors and some for comparing ribbon colors and some for comparing ribbons shapes.

(In hand the bottom Alley looks closer in shade to the bottom Ravenswood but the flash found more purple in it.)

Sooooo ... I think the ribbons of the mystery marble match the Ravenswood just to the right of it in color, except the Ravenswood has wider ribbons so they end up looking darker.  And I think the mystery marble's base is close to the Ravenswood on top.  

So that's what my vote is -- Ravenswood -- anyone else have any ideas about that one?

 

Finally, here's a non-flash photo which gets the Alley on the bottom a little better.  Need a sunlight photo but that would mean getting organized during the day.

Good luck with that one.  The nuances even within the group make for a tough ID.

You're not kidding.

But the purply shade really was a good match for the Ravenswood in hand.

Marble has already gone back home so no sunlight comparisons.

Tough one to nail down but I would bounce it between my Ravens and Alley. But I think it would stay longer in the Alleys. =}

I agree with Paul, looks like a Pennsboro Alley to me.
