Hello Rubens. Only an expert can assess the veracity and value of this stone.
We suggest contacting a specialized laboratory, as well as obtaining the certificate of authenticity, through the GIA Institute, which does not have an office in Brazil, which does not prevent you from making direct contact with them and sending the material via Sedex. And in Brazil, we suggest the IBGM laboratory:
