Side-by-side comparison of physical properties, fluorescence, and crystal system — to identify by observation.
Decisive distinctionsDECISIVE
- ◎ is higher in Morganite, giving a numerical distinguishing point.
- ◎ is higher in Morganite, giving a numerical distinguishing point.
- ◎ is higher in Morganite, giving a numerical distinguishing point.
- ◎ is higher in Rose Quartz, giving a numerical distinguishing point.
Note: properties whose numeric ranges do not overlap are auto-extracted. Both are measurable with a refractometer or heavy-liquid bath.

ObservationOBSERVATION
◆Morganite is typically transparent with distinct dichroism and higher SG variation (~2.71–2.90). Rose quartz is translucent and dichroism is weak.
