Iolite specific gravity
WebIolite is the gemstone variety of cordierite, a magnesium iron aluminum cyclosilicate mineral named after the French geologist Cordier. As with some other blue gemstones, iolite is known for its pleochroic properties. Pleochroism is an optical phenomenon where the gemstone appears to be different colors depending on the angle and light source. WebThe Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:
