To identify authentic jade, conduct a home test by visually inspecting for a waxy luster and natural flaws, feeling for a cool touch, assessing transparency against light for a crystalline structure, and checking density (heavier indicates jade). Utilizing deductive reasoning enhances accuracy. If unsure, consult a professional and consider a jade identification course.
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.
