Kyanite?

Is there anything special about this kayanite? Is it worth anything?

Not really gem quality, and not a vivid colour either, as well as being interspersed with quartz. So, I would say a collector specimen of no great value. You don't say how big it is, but this one is about 8cm in length and weighs a little over 30g.

Mine is one pound 17 cm

And the green underneath. Oolitic malachite on mafic rock?

That appears to be the rock from the OP's other thread. As I said there, Malachite does not glow under UV light. Willemite does (bright green), and occurs with that botyroidal habit, but the OP hasn't told us what colour he observes.

You really need to give a full story when posting your finds. Re-reading your other post, I now see you only think the green rock glows under UV (what makes you think it does?)... and from what you now say, it appears you haven't actually checked it yourself.

No worries. On that basis, I would go with Botryoidal Malachite for the green rock.
