yes by using specific gravity of the metals. specific gravity of copper is and of silver is It is somewhat inaccurate because we work with sterling silver so specific gravity of sterling is slightly less, but for all practical purposes it is good enough. The formula you can use is (weight in copper * specific gravity .

Oct 16, 2015· the specific gravity of .999 silver is, while .500 silver is which equals a % difference. But a 50% difference in the fineness of the metal. So your % difference in specific gravity is HUGE when it comes to the fineness of the metal. And I'm just having a hard time believing that govt. mints would debase their coins that much.

Dividing 1000 by itself yields the specific gravity of water, which is one. The larger the specific density of a material, the more dense the material is than water. Specific density can be used to determine whether solids of different materials float or sink in water. If the material specific gravity is .

Hardness: 10. Specific gravity: Uses: jewelry, saws, polishing equipment. Diamond, the hardest of any naturally formed mineral, is also highly refractive, causing light to be split into a spectrum of colors commonly called play of colors. Because of its high specific gravity, it is easily concentrated in alluvial gravels, where it can be ...

Pieces of pyrite have also been used as a sparkproducing material in flintlock firearms. Pyrite has a nickname that has become famous "Fool's Gold." The mineral's gold color, metallic luster, and high specific gravity often cause it to be mistaken for gold by inexperienced prospectors. However, pyrite is often associated with gold.

Sep 02, 2016· Criteria 3: Specific Gravity. Specific gravity measures the relative density of a gemstone. A one carat gemstone with a higher specific gravity will be slightly smaller than a one carat gemstone with a lower specific gravity. Criteria 4: Refractive Index. Refractive index measures how light passes through a material.

May 31, 2017· Re: Density (Specific Gravity) of precious metals I'd use aluminum and tungsten for most of the material properties of mithril and adamantine, respectively. There's a few properties which need changing, which involves either just cranking them up (Moh's Hardness can hang out at 11 and 12 for them), or taking properties from steel alloys.
