Who digs all this stuff out of the ground? Who cuts and polishes the stones? Are they real? Are they dyed or enhanced? Were the people involved in producing it treated well? Did they have ventilation where they were cutting? Did they get paid well? Were they children? Are these really rare or did they just say that? Is this synthetic sapphire or real? Why is that one $5 a carat and that one $15 per carat? What is involved in mining these? Does it damage the earth? Were harsh chemicals used? Were habitats destroyed?
