Moranbah Diamonds
« on: April 06, 2018, 12:58:53 PM »
A few years ago a friend worked in Moranbah and was able to collect some Moranbah Diamonds from one of the mine sites before they covered them with overburden well he called in home the other day and dropped some off for me as he is giving lapidary stuff away win for me. Photo in gallery.Dave

Moranbah "diamonds" are actually quartz.

I sometimes have trouble telling the difference between Topaz and Quartz when I've got the things in my hand  ::)

So do you find those in the creeks up there or only in very select locations?

Just curious as my sister works in the mine up there so would like to let her know.

Cheers

Where these ones came from is now under overburden if the lapidary club is still running they would be able to help your sister I dont think they are easy to find anymore.

From the picture I would have put them in the Topaz pile. Topaz have 4 sided crystals and Qz 6 sided but these are pretty worn.
Apparently Topaz feels cold in the hand.
Life is not all about the final destination, but the journey taken.

Yep Topaz is cold and has a sort of waxy feel to it, another give away if you have a 365nm UV, a lot of Topaz glows orange/yellow
