What kind of rock is dark turquoise with a bit of black and white?

It's dark turquoise with a bit of black & white. It's smooth and glassy. (I think it's been rock tumbled; I purchased the rock at a souvenir shop.) It's transparent. It also has a roundish shape. I found it in Canada - Nova Scotia. Thank you!

It sounds like the rock could be Green Aventurine, Howlite or even Turquoise itself. In addition, it looks like any of the three could be found in Nova Scotia, Canada.

I'm guessing it's turquoise. The tumbling and glazing process might have given it a darker shade.

First deciding if your rock is igneous, sedimentary or metamorphic. Then you will check the grain size and hardness. Look online or in a book for help.
