Diamond    The Australian Diamond.

Diamond –is an outstanding natural material. It Hardness, high lustre, fire and clarity makes it unique. Marilyn Monroe song Diamond being a girl’s best friend. How right she was.

Now something about diamond, I would love to be able to understand more about how to find diamonds.

Diamonds originate in the earths mantle. They are usually transported to the surface in volcanic pipes of kimberlite or lamproite  rock. From  these they wash into rivers and often finish up in alluvial deposits far from their source .However, some eastern Australian diamonds are unusal and may come from a source other than the typical kimberlite or lamproite.

Diamond is the hardest mineral on earth. Diamond-tipped drill and saws can cut through any substance. The glittery brilliance of the diamond makes it the most valuable gemstone in the world. Hardness is 10.  

 

Diamond is used to cut a lot of other stones and rocks, Diamond- tipped drills and saws are used to cut and drill through meters of dirt to find water or other minerals. Also in a smaller scale to cut and polish gemstones for jewellery.

dia1How do you know what a diamond looks like. Diamond hardness is a 10. It can cut any material, and nothing will stick to it.  The picture to the left shows a sparkle rock on the side of another rock.

I need to know more. Well The chances of finding a diamond are 1 in 10,000,000.Diamonds are cubic (isometric) form. The most common mineral that looks like a diamond is quartz and it is hexagonal form.When looking down on the crystals from the top, with the point of the crystal aimed at your eye, quartz will have six sides and a diamond will have four sides. Topaz has eight sides.

Don’t scratch glass-most gemstones will do that. The only hardness test that will identify a diamond is Scratching  Corundum. Corundum, which includes all Rubies and Sapphires Gems, is 9 on the hardiness scale

What is Corundum

Corundum is an aluminium oxide that commonly forms hexagonal barrel-shaped prisms that taper at both ends or as thin tabular hexagonal plates. Its hardness of 9 on the mohs scale, making it one of the most durable commercial  gemstones. Comes in all coloured of the rainbow. Red Is ruby.

 

What is Ultramafic.

Describing igneous rocks that contain magnesium and iron and only a very small amount of Silica, such as are found in earth’s mantle.

What is Kimberlite.

Kimberlite, an ultramafic volcanic rock , is quite rare but much sought after because it is the ore of diamond

Kimberlite is a peculiar rock that erupts very rapidly from the deep in the earths mantle, leaving behind a narrow pipe of this greenish brecciated lava. The rock is of ultramafic compositionvery high in iron and magnesium and is largely composed of olivine crystal in a groundmass consisting of various mixtures of serpentine, carbonate minerals, dropside and phlogopite. Diamond and many other ultra-high pressure minerals are present in greater or lesser amounts. With the Volcano  Eruption ,carries the kimberlites – along with any diamonds they contain – to the surface.

What is lamproite

Lamproite-  A variety of lamprophyric extrusive rock rich in potassium and magnesium.

Kimberlite and Lamproite – Host rocks for Diamond.

Kimberlite is very difficult to recognize. It Is basically a potassic  peridotite and comes in a variety of colours and textures.

 

 

 

                                                                          Ruby

Rough Ruby Gemstone
Rough Ruby Gemstone

Ruby are variety of mineral corundum. Ruby Deposits however, are rarer than sapphire deposits because they are dependent on the presence of the element, Chromium.Chromium gives ruby its red colour, with modification from iron, titanium and vanadium. Ruby is usually found in metamorphic rocks. Found Hart range in the northern territory. 10 hour drive from where I live. A Place I will be going to one day ( It host a lot of different gemstones)

 

 

Emerald

Emerald is  the most famous and valuable green gemstone. Dark green is the most valuable colour of emerald, the light colour are of no value.

 

                                                                          Sapphire                          

Sapphire is a gem varieties of mineral corundum, an aluminium oxide. This mineral is coloured by additional trace elements  in its structure. Sapphire come in all colours. except red which is ruby.

Have a great day.

Gemstones North Queensland- Gems -Fossicking Area’s

OLYMPUS DIGITAL CAMERA
Copper ore

Gemstone fossicking in Queensland

What to do.

Where to go.

What to look for.

Gem Fossicking Qld.( Rockhounds ). Looking for “that” natural gemstone.

Love to go Fossicking for Gemstones.

Hi, one of my many hobbies, (love to do in my spare time) is to go out fossicking for gem stones. Sunday afternoon don’t wont to do anything at home , we will get in the car and go for a big drive. We stop a lot off times,  to look around,   walk around looking at the ground.  We are always bending over then walking again. Up Down Up Down . Always looking down for that sparkle on the ground.

What to do when looking for Gemstones in North Queensland.

When you are about to go looking for gemstones, it is a good idea to do your research before leaving.  In Queensland you need a fossicking licence when looking to find gemstones. There is a fine if you are caught with out a licence. I have been out in the bush, miles from anywhere and was asked for my Fossicking licence.

Designated fossicking

Make sure you are allowed on the property  you can find out information if you visit fossicking licence , if it is designated fossicking land. you are. Are you allowed to camp there, Is there running water, Some have toilets and showers. All this information you can find out buy visiting  here

What to look for.

Looking  for Gemstones , yes  you  do need to know thing like different in the soils .  What is the different between a crystal and a topaz, when  you  find a  Gem.  Why some Topaz are rounded and others have 8 sides. Gemstone  fossickers  dream, is to come across the shining/sparkling rock, that nothing sticks to it because it is to hard. That Diamond. Wouldn’t it be nice.

Field  Trips.

We went with our local Lapidary Club , looking for topaz in June 2017,  There was lots of different people there, we were all looking for the same things like-  Topaz- Aquamarine.  Smoky Quarts , and more. Every one has different ideas, finding topaz.

Finding Topaz.

We went to a place called O’Brien Creek. it is in Central North Queensland. To find a piece of Topaz ,   you will  have to move a lot of dirt to get a Topaz Gemstone. Topaz is every where you just have to be lucky to dig in the right place. The idea is to find a spot and start digging, you have to use a sieve to look for topaz. Topaz looks like a clear stone in you sieve. Pick it up and it feels cold, lots of people put them in there mouth. It is like a quarts crystal, but when you pick it up it feels cold. The Topaz we found were in the river so they were mostly rounded stones of all shapes and sizes ,  when you put them in your month, or wet them they become clear.

Old Stories about Topaz at O’Brien Creek.

Years ago Topaz was every where at O’Brien Creek. (find out about the camping at O’Briens Creek.) People tell stories about digging into the sand , throw  a shovel of sand out of a hole and the topaz, you used to watch them jump out of the sand,

A golf Ball.

While we were there a local found a piece of Topaz the size of a golf Ball. Never got to see it. This person just dug a 2 foot hole and found it. Lucky.

O’Brien Creek Old Tin Mine.

There was a tin mine at O Brien creek, the Topaz was dumped with the other unwanted minerals.

Find Aquamarine.

Aquamarine is at O’Brien Creek, you Have to be very luck to find that Gemstone. Years ago it was every where. We bough a nice piece in town at Mount Surprise.

Mount Gibbson – Topaz and other Gemstones

Another place to find Topaz is Mount Gibbson.

 

Chrysocolla.

I am going to take you to find Chrysocolla. 

OLYMPUS DIGITAL CAMERA
Falls to Pieces

It is a copper bearing mineral found wherever copper deposit  occur. Chrysocolla is a gemstone.  It is a beautiful skyblue to bluish – green colour. Copper is its chemical  structure. Is multi-coloured with inclusion or veining of black & brown matrix material. It is not a popular gemstone because of it hardness, when cutting it, the stone has lots of fractures and falls to pieces.

I have a piece of chrysocolla  that has native copper in it.  Native copper is like copper wire everyone uses for there electric cables. My piece has lots of colours, copper,  silver,  quartz, veins , skyblue, a light green brown & black. It is a very pretty gemstone. Find some and give it a go, you will find such beauty, in one stone.

Chrysocolla is found worldwide, though significant sources include the Congo (Zaire), Israel, Australia, Peru, Chile, Mexico, and in the U.S. in Arizona.  In North West Queensland, Australia , it is everywhere.

What you are looking for is a greenish, skyblue, dark  blue rock . Pretty colours. Use you fingers to see if you can brake the rock.  You don’t want something that  crumbles keep looking. It is easy to find. At lot of rocks have the white quartz through them, You don’t want a stone that has to much quarts more blue, green, greenish, greys, and blacks in the colour of the rock.

OLYMPUS DIGITAL CAMERA
Cut chrysocolla

Out here we have a lot off old mining company that have closed down. Two mines Wee MacGregor Mine & Mary Kathleen.  They are pretty close together. Mary Kathleen is a old uranium mine, Lots of Copper mineral out there. Wee MacGregor Mine is ,was copper.

Mary Kathleen.

Is 64 kl from Cloncurry, Nearly half way between Mount Isa & Cloncurry in north west Qld. That road is the highway so it is bitumen. There is signs up saying Mary Kathleen. Watch out once you get of the highway it is quite a rough road so slow down. You can explore all the roads left and right. If you go straight ahead you will see the open cut the mining company just left, everyone reckons poison water.

In the Late 70s we use to go to Mary Kathleen for social days. As you go over the grid of the highway, to your right was a dirt  golf course, I can remember playing golf there, down the road a bit more to your right was the township, shopping centre. Mary Kathleen had a  fruit tree farm, always went and bought oranges on our way home to Mt Isa

There is a lot of different rocks/stones, you can find at Mary Kathleen. Copper Ore, Fouls Gold is everywhere. You find the Peacock Ore, which has all the colours of a rainbow. Very nice stone. Your copper rocks that have a greenish sky blue to dark blue colour, with quarts and other minerals in it. Make sure you pick some up and cut them. If they hold together you can get a really pretty stone. This your Chrysocolla stone.

On this website you will read more about looking and what to do with certain gemstones , in North West Qld.

If you have any Question, Want to know where to go , what to look for, anything leave me a comment and I will get back to you.

Have a Great Day.
