The differences between “green garnet “and red garnet sand
Both “Green garnet” and red garnet sand are from underground,natural minerial order,both are mainly for sandblasting and waterjet cutting.
In fact,”Green garnet” is not garnet sand,it is Omphacite.
Now we mainly talk about the differences between them.
Red garnet sand

Specification of red garnet sand
Chemical compostion
| Silica SiO2 | 34-40% |
| Iron(Fe2O3+FeO) | 25-31% |
| Alumina Al2O3 | 17-21% |
| Magnesium MgO | 5-6% |
| Calcium CaO | 5.0-10.0% |
| Manganese MnO | 0-1.0% |
Mineralogical Content
| Almandine garnet | 97-98 % |
| Quartz | ≤0.2% |
| Ilmenite | ≤0.5% |
| Others | ≤0.1% |
“Green garnet”,in fact Omphacite

Specification of “Green garnet”,in fact Omphacite
Chemical compostion
| SiO2 | 54-58% |
| Fe2O3+FeO | 3-5% |
| Al2O3 | 12-14% |
| MgO | 5-7% |
| CaO | 8-11% |
| MnO | 0-1% |
| Na2O | 6-8% |
Mineralogical Content
| Omphacite | >85% |
| Almandite Garnet | <15% |
| Ilmenite | <0.5% |
| TiO2 | <0.5% |
