kyanite

May i ask the going price for
samples such as the attached
from Tres Pontas
Brasil

There pictures don't really give a sense of scale, so it's hard to say. Assuming a size of approximately 6 inches, I'd say $10-$20 would be the usual price... there is tons of the stuff around, so as always, it depends where you shop. A wholesaler might sell them for $5, a metaphysical dealer for $30, etc.............

HI Ibrahim..thank you for this response and also the one

Ibrahim is right on.

Perhaps $30 to 40 a kg can buy all of them you want in Brazil. Kyanite as mine run is not fun to clean. A lot depends on how well they are cleaned. If a lot of the quartz is worked out from between the blades so that the kyanite blades are more prominent, those cost more. I have bought nice loose kyanite blades for less than $10 per kg, but now that the US currency is in decline and the Brazilian currency is strong, things are not as they used to be.

I have not written about cleaning kyanite, but you can clean them with the same reagents that you clean quartz with, however I would not use any reagents containing fluorine until you have experimented with it to see for sure how it reacts.
