Density Test- Measure specific gravity of gold and silver jewelry.

Learn to measure the specific gravity of gold, silver, and other metals with a gram scale. I use this technique to Identify gold jewelry without marks for purchase. My scale is sensitive to 0.1 grams, I find at that sensitivity I can measure objects 2 grams or bigger with this test. Ring 11.8g metal and stone, 1.4g H2O displaced. Bucklem26.8 g metal, 2.6g H2O displaced. 1g H2O= 1cm3 To calculate density take the weight of the object and divide by the water displaced. Ring= 11.8/1.4= 8.428 g/cm3 Buckle = 26.8/2.6= 10.31 g/cm3 Common densities of jewelry and base metals, roughly: 10k gold 11.0g/cm3 14k 12.5g/cm3 18k 14.5g/cm3 22k 17.7g/cm3 24k 19.32g/cm3 (.999 fine) copper 8.94g/cm3 nickel 8.90g/cm3 lead 11.34g/cm3 tungsten 19.3 g/cm3 glass 2.7 g/cm3 Have a question?
