Type M Tourmaline

[STails]

I''m looking for information on what is being called type M Tourmaline. It is from Mozambique. It is green in color, and very refractive. Any information would be helpfull.

Are you referring to the tourmaline''s they are selling on DSN? If so, they are from Mozambique and just call them Type M for short. I have one myself.

I thank you for your reply. Yes I have several, but I''m tring to find out there value since knowbody has heard of them. Any ideas? Even my lab where I get my material appraised has never heard of them,makes me wonder.

Artistic Colored Stones has a number of Tourmaline from Mozambique for sale ranging in price from $60 to $120 a carat. There''s only one green one and that''s going for $100/carat.

I am not sure too many people have heard of these type of tourmaline''s that we have. They sure are pretty though, with the blue/green. I am thinking of having one of mine made into a ring. I know I searched e-bay once and found them there too.

The value depends on where in Mozambique the stones are from. There was a recent find of copper bearing tourmline in Moqambique that when heated turns neon. The AGTA has just approved the term Paraiba to represent all copper bearing tourmaline, not just the ones from the original find in Brazil. The BEST of the Mozambique copper bearing tourmaline is much better looking than the Nigieran and very close to the BEST of the original Brazilian stones. As in even Brazilian Paraiba Green is relatively in expensive but blue and green/blue is.

Thanks for the info. My stones are blue green, I have several. They flash both a bluish green and a greenish blue. How much do they go for a carat? Is there somewhere I can read about these stones?

For stones in the 1-3 ct. range depending on the color and cutting I would think $100 to $150 / ct would be a reasonable wholesale price.

Hi Gene,

That depends on if they are copper bearing or not.
