Diopside (?)

Bright green crystal with great color and transparency. I bought this from Steve Ulatowski perhaps a year ago. He got it with a batch of Dravites he purchased directly at the mine site in Mwajanga. I have seen Diopside and Kunzite crystals from this mine so there are other things being found there besides Dravite, so the locality could be correct, however to me this looks like Diopside from Merelani. The species and locality are uncertain. I paid $100 for it, but it's been sitting on my desk for too long so into the auction it goes.
