I don't see bubbles in your photos, unless the little black spots are small bubbles. The apparent lack of conchoidal (shell-like) fractures and the curved but sub-parallel lighter streaks make me suspect it may be a metamorphic rock. Please take up Barbra's offer and send her a chip to ID.

Canadian Nephrite Jade has black spots. To the best of my recollection.
