Weight, Carat and Size is important to know when buying and selling gemstones. It is hard buying gemstones with out seeing it, Often the larger the stone the more valuable it is, not the case. You have to take in the colour, clarity, and inclusions (flaws). Picking up a gemstone, look at it under a light or loupe, If you can see right through it , is a good sign it is a great gemstones. Check the size dimensions in millimetres when you are buying gemstone and don’t rely on carat weight alone.
My first gemstone I bought was a green diamond it was .01 carat stone, 01 Carat stone is the size is smaller than a grain of fine sand. The gemstone was a green diamond, cost $10 Australian Dollars, if you look at it under a loupe you can see about 18 faceted cut in the stone. The $10 was a great investment as it is a real eye opener .I don’t know if it was a real diamond, at a guest no.

In fact a fine quality amazonite can be mistaken for precious jade. Amazonite does not undergo any kind of treatment.

All Year round Fossicking.
In the hotter months you do not do much fossicking because the rocks are even very hot, having a air conditioners in your cars, and having shade when you go fossicking make it a nice day out. You have to start out very early in the morning. Out here it is day light at 6am and it is still day light at 7pm at night, in the summer months.
When there is no rain.
Camping And Fossicking in cooler Months of the year.
I live in Mount Isa. North West Queensland. Only over the past 4 years have I been Interested in Fossicking for Gems- Stone. I am still a newbie. Lots more to learn. Fossicking is all year hobby. When there is rain, no way do you go on a dirt road, you are asking for trouble.
North West Queensland Fossicking Area’s.
You have to have a Fossicking Licence, before you can go Gem hunting in Queensland. If you are looking for gems-stones-rocks-gold, you have to have a licence,
Out here you can explore the country side, bush, if you have a 4 wheel drive and a good GPS. So easy to get lost.
Get Permission.
Remember the land belongs to some one, so you could need permission to go on there land. Find out from the locals Lapidary Clubs. Or go to Government website to find out more..qld.gov.au
You are stupid if you go out exploring when it is wet. Raining.
We nearly got caught, 3 times in 2016 June, July and October. We packed up quick, we could see the rain coming. We were lucky we did not get stuck in the mud. The clean up took a week to do. Not much fun.
Weather. No Phone.
In the North West we do not get very good weather reports, our report is possible showers that never happen. over phone coverage is gone 5 minutes out of town. That is why you show have a good GPS. Ours has bird eye view, so you can see the country side ahead of you. It tracks you where you go, and when you get out of the car, you put it in your pocket. No chance of getting lost that way. If you have not got a GPS mark your trip, when you get out the car mark your track, use rocks.
Take your own water.
Take your own water, most of the creeks beds are dry. Water for drinking and washing your hands and stones.
Out of Date Books.
There is a lot of books out there that are out of date. Pictures Most Placers are not accessible in the wet. our country is red/black mud. even a 4 wheel drive can not handle it most of the time. Going on roads after flooding only wrecks the roads for everyone else. No one grades the roads we go on, if you check with your insurance company you will find even your car is not insured on these roads.
Want to go Fossicking. Not Sure where to go.
If you want to go fossicking and you are not sure where to go, Ask your Question, I might be able to answer you. Most people out here are very friendly. Best idea is to go into the tourist shop, in the town you are visiting, buy a sample of the stone you are looking for. ( Remember to support these shops they have to make a living).
