A nice cabinet cavansite specimen.  There is a bit of damage , but the price takes this into account and there is a lot of cavansite on this specimen.  

 Cavansite is no longer as rare as it was 15 years ago, but the fact that this piece has top color, multiple rosettes, and no damage makes it considerably better than the average.

 I remember in the mid-90's a popular internet dealer posted a page of cavansite, and single sub-1 cm rosettes (off matrix) were selling for prices up to $500.  Today those same specimens would sell for $1 and something like this is now affordable.
