The picture below is a Hematite rock I found , when you touched it , your hands, are full of sparkles. Very shinny silvery rock.
Hematite is iron oxide that gets its name from the Greek word for blood.
Hematite forms in the rhombohedral crystal system.
The same crystal structure as Sapphire and Ruby. I have been told if I look at my Hematite Rock with a magnifying glass I should see small red crystals.
Hematite is always opaque and is typically a blackish grey. in the sun it looks like a silver rock, it is very heavy to pick up, and sparkles. Very Pretty Rock.
The rock above has had nothing done to it yet. One day I will cut it.
What to do with Hematite.
It is commonly cut as cabochons, faceted or sold in the form of engravings, which are particularly popular. Hematite was a traditional material for signet rings. When highly polished it can sometimes look like silver.
More to come about this rock, at the moment it is in my garden.
Have fun rock hunting.
