Specific gravity of stones
http://www.csgnetwork.com/specificgravmattable.html WebThis imitation red and pink coral has a specific gravity (SG) of 2.44. This is always lower than natural red and pink material. This synthetic has weak birefringence and lacks natural structure. Under high magnification, you can see a fine granular texture. Plastic imitations can be identified through hot point testing or acid testing. Only ...

WebSpecific Gravity. Specific gravity is a unitless number describing how heavy a mineral is compared to equal volumes of water. For example, if a mineral is three times as dense as water, it’ll have a specific gravity of three. ... If you want to determine the specific gravity of your stone like a pro, you’ll need to invest in a higher-end scale. WebFor all gemstones listed in this table there is a scientifically determined specific gravity. You can use the specific gravity and a couple simple measurements to estimate the carat weight of a stone. We have created a calculator that makes a gemstone carat weight estimation using this principle.
Gemologists usually measure specific gravity with heavy liquids. They prepare a liquid, such as a mixture of bromoform and toluene, to have a particular density value. When an unknown material is dropped into the liquid, it may sink, float, or remain suspended in place. If the material sinks, it has greater … See more In case you forgot your high school science, density refers to how much mass something has per unit of volume. Or, think of density as the "compactness" of an item. For example, vegetable oil is less dense than vinegar. … See more The density of a compound is a function of several factors, including chemical composition and crystal structure. For example, consider diamond and graphite. Both are polymorphouscrystalline forms of the element carbon … See more The presence of impurities within crystals poses a major problem for all gemstone density measurements. These impurities hardly ever have the same specific gravity as the host material. … See more
