Kunzite vs Morganite
Kunzite and Morganite are commonly confused, and 3 measured properties separate them — crystal system most clearly.
Kunzite vs Morganite
Kunzite
Pink spodumene — a difficult stone to cut, and one whose colour can fade in daylight.
Morganite
Pink beryl, coloured by manganese — named for a banker, and a gemstone that became fashionable a century after it was described.
| Property | Kunzite | Morganite |
|---|---|---|
| Crystal system Categorical values can be listed side by side but not ordered or subtracted. | monoclinic | hexagonal |
| Density | 3.15–3.21 g/cm³ higher | 2.71–2.9 g/cm³ |
| Mohs hardness Mohs hardness is an ordinal scale: values can be ranked, but differences and ratios between them are not meaningful. | 6.5–7 | 7.5–8 higher |
Why these get confused
both pink and both from pegmatites; kunzite has perfect cleavage and much stronger pleochroism, and is denser
The confusion is a real and documented one, not a resemblance we have invented.
