Black serendibite price

HI,

Looking for a guide to serendibite price

Black color from Mogok price per carat? Realtively opaque

Is a 10+ carat more valuable and rare ? Is it an auction gem ?

thank you

About $50/carat from Bangkok wholesalers such as Multicolor

I bought a few of these alleged “Black Serendibites” and after two different gem labs and several hundred dollars in testing … they really turned out to be black diopside. A word to the wise. :))))))))
