I'm going to throw doubt on the "molded hematite" or
"reconstituted hematite." (Incidentally the UK spelling - from the
Greek for blood - the red streak that the material makes when drawn
across a white unglazed ceramic surface - is heamatite)
No. The English spelling is haematite, which the the Concise Oxford
defines as: a ferric oxide ore forming dark red or reddish-black
masses. [Latin haematites from Greek haimatites (lithos) ‘bloodlike
(stone)’ (as haematin)] I have another supplier who uses the term
’hematine’ for reconstituted material; the point is to distinguish it
from the natural material.
I've qualified as a gemologist so I know a fair bit and I've
never come across any reconstituted material.
Actually, I buy from suppliers who are also qualified gemologists,
who say that what they are selling is reconstituted material.
Even if a suppler says that that's how their beads or cameos are
made I think they are mistaken and that the they
supplied is incorrect.
They are being honest, not ignorant. There is a difference.
