We purchased this gemstone from a contact with direct access to the mine location and with whom we have maintained a long and trusted business relationship. Our supplier has clearly reported on the exact mining locations and production practices applied. On several occasions we have visited the mining operations ourselves and have witnessed the extraction process. We therefore have very good visibility of the gem's life cycle and can testify fairly confidently to the provenance of this gemstone.
