With a particular gravity of six.seven to 7.one, cassiterite is one of the densest gem components acknowledged. Through comparison, the extremely dense hematite σταυρος γυναικειος διαμαντια has a particular gravity of around 5.28, when the specific gravity of sapphire is about four.03 Which of diamond is 3.53.
