Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities?

Here will go a good picture of a quartz specimen from Angola and general remarks about the quartz from this country.


Here are some url's to some of the better quartz specimens here on mindat that can be considered for inclusion in the article. These, in most cases are just for temporairy use untill we can get images of the much better specimens that are almost certainly out there. We should also consider that there are probably localities out there with fine specimens that are not even mentioned on mindat. Also in some instances there are sometimes pictures on mindat, of specimens from a locality, but they were so ratty that I did not include them here, but there may also be relly good specimens from there that we should talk about in this article.

Dear Rock,

This is Joe from China, and we want to import quartz crystal from Angola or Russia all the time, but I have no found any local crystal company to contact. Do you have some good idea to me? Thanks a lot. Of course, we can talk about much more next details.

Looking forward to hearing from you soon.

Have a nice day.

Joe,
Sorry, but I don't know of any mineral dealers in Angola.

Rock,

About Angola again !
Now with quartz.
It must have been 1957-1958, the road between Matadi (Congo DR) and Noqui, border city of Angola was enlarged and changed to improve transportation.
Mid august 1958 I was sent back to Belgium by boat to be able to attend school for a complete year.
My parents and sister remained in Congo. On week-ends they went often to Noqui for swimming, where they had opened a few years earlier a new swimming pool.
Somewhere on this roadcut they found a fault with a fissure containing very light colored amethyst, some of it with an opalised layer.
There are as far as I know no known references for it.
The location is about 5°52'13" S and 13°25'52" E.
I attached 2 photo's of such specimen (Noqui01 is about 16x11x8 cm, Noqui03 is about 20x15x9 cm).
I'll add photos to the database as well as the location.


Rgds, Paul
