Are they all zoisites

Tough tough tough Zeolite!

I've got several thoughts but let's start with this ...........

Different varieties of the quartz family, i.e. amethyst, prasiolite etc. However the top gem is throwing me off so this guess is probably wrong!

p.s. Colormyworld - if they're all zoisites then I WANT and NEED the third one!

Only rarely have I seen such a green in zoisite but it does exist.

Superb guess, colormyworld! Yes, they are all unheated zoisites. I bought all three from rough and then they were cut. The green one was quite expensive. But the pure blue is also rare. I''ve never seen blue with no purple in it; even then the blue is usually much darker. And even the pure purple is unusual; usually all tanzanites show both some purple and some blue. I though I could fool you, but you''re too sharp!
