How Do You Test Jade Density with Water?
To determine jade’s authenticity, testing its density using a water displacement method is reliable. Weigh the jade, record its weight, and then submerge it in water to measure the displacement. The density, obtained by dividing the mass by the volume of water displaced, should match the known values for real jade (2.9 to 3.3 g/cm³) for genuineness. Comparing your results to a gem density table can confirm if it’s genuine jade or a substitute.
