How to Identify Morganite
Morganite is usually pink, peach, and salmon with a vitreous luster and is transparent. It has a Mohs hardness of 7.75. It scratches glass, steel and even quartz; only harder gems will mark it. Its streak is white. It is most often confused with Quartz, Spodumene, and Microcline; the tests below separate them.
Morganite identification checklist
| Color | Pink, Peach, Salmon, Pale violet | Look at a clean, dry surface in daylight. Color zoning, banding or spots are as diagnostic as the hue. |
|---|---|---|
| Luster | Vitreous | Fresh surfaces shine like glass; a dull surface usually means weathering, so chip or wet a corner. |
| Transparency | Transparent | Hold a thin edge up to a bright light and note whether light passes through. |
| Mohs hardness | 7.75 | It scratches glass, steel and even quartz; only harder gems will mark it. |
| Streak | White | Drag a corner across unglazed porcelain (the back of a bathroom tile) and check the powder color. |
| Cleavage | Imperfect on {0001} | |
| Fracture | Conchoidal to uneven | Broken surfaces show smooth, curved, shell-like scoops. |
| Specific gravity | 2.8 | Ordinary rock-like heft (specific gravity about 2.8), similar to quartz. |
| Crystal system | Hexagonal |
Extra tests for Morganite
Glass check. Morganite shares a glassy luster and conchoidal fracture with man-made glass. Glass sits near Mohs 5.5 and often contains round gas bubbles, so a hardness test and a hand lens separate them.
Morganite look-alikes and how to tell them apart
Both sit near Mohs 7.75, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. Morganite vs Quartz →
Morganite is harder (Mohs 7.75) than Spodumene (Mohs 6.75), so Morganite will scratch Spodumene and not the other way round. It scratches glass and a steel knife and cannot be scratched by a steel file. Morganite vs Spodumene →
Morganite is harder (Mohs 7.75) than Microcline (Mohs 6), so Morganite will scratch Microcline and not the other way round. It is about as hard as window glass: a knife barely marks it, while a steel file (Mohs 6.5) will. Morganite vs Microcline →
Both sit near Mohs 7.75, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
Is my Morganite real?
- Hardness: real Morganite sits at Mohs 7.75. Glass imitations are about 5.5, so genuine Morganite scratches glass while a glass fake cannot.
- Bubbles: round gas bubbles under a 10x loupe mean glass or resin, never a natural stone.
- Color: dyed material concentrates color in cracks and pores; look for pigment collecting at the edges of fractures.
- Temperature: natural crystals feel cool and take longer to warm in your hand than plastic or resin.
Field tips
- Look for a soft pink to peach transparent crystal with a hexagonal habit and vitreous luster.
- Morganite is hard at about 7.5 to 8 and shows weak basal cleavage and conchoidal fracture.
- Color and crystal form distinguish it from pink topaz, kunzite, and pink tourmaline.
Morganite identification FAQ
How can you tell if a rock is Morganite?
Check the color (pink, peach, salmon, and pale violet), the vitreous luster, a Mohs hardness of 7.75 and a white streak. Photographing it with the StoneSnap app gives a match in seconds.
What is the hardness of Morganite?
Morganite has a Mohs hardness of 7.75. It scratches glass, steel and even quartz; only harder gems will mark it.
What is the difference between Morganite and Quartz?
Morganite (Mohs 7.75, vitreous luster) and Quartz (Mohs 7, vitreous, greasy on fracture surfaces luster) look alike, but hardness, streak and heft usually separate them. See the full Morganite vs Quartz comparison for a side-by-side table.
How do I know if my Morganite is real?
Real Morganite matches the hardness listed above, shows no round gas bubbles under magnification, and does not concentrate dye in cracks. Glass and resin fakes fail at least one of those checks.
Is Morganite worth anything?
Entry-level Morganite specimens sell for around $30, typical collector pieces about $250, and premium examples $2000 or more depending on size, quality and locality.
What color is Morganite?
Morganite is most often pink, peach, salmon, and pale violet. Color varies with impurities and locality, so confirm with hardness and luster rather than color alone.
