Okay, then I'll show you a similar color in Heaton, dark amber base with white and bluish bands.
But yours seems to have seams, while in Heaton they are totally absent as swirl
But I want to show anyway ...
However, sometimes, some notice tiny inclusions in the green and mistake it for aventurine, but it's actually just undissolved dye.
If your glistens in the light or the sun, it's av, otherwise it's just (as I said) undissolved dye
