📜 Key facts
| Age | Varies; Sri Lankan and Burmese spinels formed in metamorphosed marbles |
|---|---|
| Origin & sources | Sri Lanka and Myanmar (Mogok). Star spinels are rare. |
| Composition | Spinel (MgAl₂O₄) with oriented needle-like inclusions |
How it forms
Spinel is cubic, so inclusions can align along several directions at once. This gives 4-rayed stars, or 6-rayed stars when the stone is viewed along a different axis.
