The most common equation for the specific gravity (SG) of a mineral is this: It's pretty simple to work out: 1. Weigh the mineral in air (literally put in on the scales like normal) 2. Suspend the mineral in water for the second weighing. Legend has it that is was Archimedes who discovered that the weight of the mineral in air minus its weight ...

Goethite is an important mineral in various geological and environmental contexts due to its widespread occurrence and its significant role in processes like iron cycling and mineral formation. Goethite typically crystallizes in the orthorhombic crystal system, forming prismatic or needle-like crystals, as well as in massive, botryoidal ...
Mineral density, or the mass per volume, and specific gravity, or the ratio of mass to an equal volume of water, are used to identify minerals. Learn more about these properties and discover how ...
Quick Test Method for Determining Specific Gravity of Mineral Specimens by John Betts, lecturer, author, photographer, mineral collector, and part-time mineral dealer.
Minerals can usually be identified by their specific gravity (SG). Because samples of the same mineral may appear quite different, as these samples of cinnabar show, a quantitative, objective measurement like SG may help confirm their identity.

Measuring specific gravity helps gemologists identify gemstones. The following table lists the specific gravity values for a variety of gem materials.
The term "heavy" refers to their high specific gravity (i.e. greater than 2.85 g/cm 3 or denser than bromoform, or denser than non-toxic sodium polytungstate at 2.90 g/cm 3) relative to light minerals such as quartz, feldspar, and Ca–Mg-bearing minerals (Mange and Maurer 1992; De Meijer 1998; Dill 1998, 2010; Andò 2020 ).
Hematite is one of the most abundant minerals on Earth's surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe 2 O 3. It is a common rock-forming mineral found in sedimentary, metamorphic, and …
Specific gravity. The weight ratio of a mineral as compared to water. The heaviness of a mineral has to do to the density of it atomical arrangement and the combination of the element s it contains. See Specific Gravity in Mineral …
In his mineral identification tables, smith (rd,entifi,cati,on a d.qual,itatioe cherai,cal, anal,ys'i,s of mineral,s,second edition, New york, 19bB) groups minerals on the basis of specific gravity but in each of the twelve groups the minerals are listed in order of decreasinghardness.
Specific gravity (also known as "relative density") is the ratio between the weight of a stone in air and the weight of an equal volume in water. By convention, the temperature of the water is 4° C and at standard atmosphere because the density of water is greatest under these conditions. Room temperature conditions are adequate for ...

The specific gravity of a substance (when referred to water at 4°C) is numerically equal to the density of that substance in the metric system. The specific gravity of milk is usually expressed at 60°F (15.6°C).
Specific gravity (SG) is a related measure that geologist's use to describe the density of a mineral. For the purposes of this course, the specific gravity of a mineral can be described as "low", "moderate", or "high".

What is specific gravity? It is the density of a substance relative to water. As an example, when we say that the specific gravity of quartz is 2.65, we mean the weight of quartz is 2.65 times that of an equal volume of water. Their are a number of ways to write the equation for the specific gravity (SG) of a mineral. Here is the most common:
