Physical properties
Hardness: 9.0 on Mohs scale; Color: Pink; Luster: Vitreous/Adamantine; Crystal System: Trigonal; Specific Gravity: 3.95-4.10
Formation & geological history
Formed in metamorphic rocks seperti marble or schist, and in igneous rocks like basalt. Originates from high-pressure, high-temperature geological cooling processes over millions of years.
Uses & applications
Primarily used in high-end jewelry (rings, earrings, necklaces) and for industrial abrasive or laser technology applications due to extreme hardness.
Geological facts
Pink sapphire is technically the same mineral as ruby; the only difference is the saturation of color. If the color is too light, it is a pink sapphire; if it is deep red, it is a ruby.
Field identification & locations
Identified by its high refractive index, extreme hardness (only diamond can scratch it), and lack of cleavage. Commonly found in Sri Lanka, Madagascar, and Myanmar.
