WebThe white colour is due to minute fluid inclusions of gasoline, liquid, or each, trapped at some point of crystal formation, making it of little value for optical and first-rate gemstone packages. Rose quartz is a type of quartz which exhibits a pale purple to rose red hue. WebHence the process of crystal formation is spontaneous below the equilibrium melting point(Tm ∞)∗∗ while the reverse process, i.e. crystal melting to form liquid is spontaneous above Tm ∞. At T m ∞, a condition of equilibrium exists between the crystal and liquid as both phases have the same value of G and ∆G= 0.
