Some facts about our North Queensland agates
1) Agates from Agate Creek North Queensland are world wide
known amongst agate collectors as the most colourfull agates,
with the most spectacular patterns .
2) Agate Creek agates are more and more difficult
to find, let alone good ones!
3) Only about 30 % of those agates dug up, cut
and polished are collectors items!
4) Agate Creek is only accessible by 4-wheel
drive and is far away from any form of civilization and is
situated about 500 km south west of Cairns, North Queensland.
( 400 km from The Atherton Tablelands)
Average temperatures are around 40% C
From 1965 till 1969 René and Nelleke
Boissevain went back and forward from The Atherton Tablelands
to Agate Creek, to dig up agate nodules in the unforgiven
heat of a barren country , using only pick and shovel and
being pestered by millions of flies!
To cut and polish agates is a process, some
people do not understand...Let me explain.
In the first place you need the expensive machinery to
cut agate nodules in half.
Because agate is harder than steel you need diamond
sintered blades to do the job.
Again,you must realize, that only about 30 % of Queensland
agates are good enough to sell as a collectors item...
The next step is the grinding down of the saw marks
..
This is done by using a slow turning steel plate.
A paste of 80 grit silicon carbide is smeared on and the
agate half is than pushed down by hand onto the plate moving
it back and forward...The process is followed up using the
same method with grit nr 220, than 600 and the final polish
with tin oxide..
The method with vibratory flat laps is also used.
Of course cutting agates is exciting ..You never
know when you cut that museum piece !
Once in a while that happens and it makes up for so many missers.!
These museum quality agates , despite their price bracket
are more easy to sell , but sadly enough they're rare.
Collecting agates of a good quality is an interesting
and also profitable hobby!
We hope that collectors, beginning collectors and whoever
read this will have a better understanding , about location
of agates, digging,sweating,cutting, polishing and marketing.
Agates are among the most beautiful creations
the world has bestowed upon us. Formed millions of years ago
in the earths crust from a combination of quartz and different
elements, no two are alike.
There are many different types of agates and
the name depends on where the agate is found. The agates displayed
on this web site are found at a place in Queensland - Australia
called Agate Creek. The agates found at Agate Creek are some
of the most beautiful in the world.
Some other types of agates are as follows:
Agate Creek Queensland Agate
The agates we sell here on this site were mined
during the mid '60's, in the unforgiving heat of the North
Queensland Australian outback, René and Nelleke Boissevain
used only pick and shovel to gather these agates. They are
among the most rare and beautiful in the world.
They were first noted by early gold prospectors
in the Gilberton area south of Georgetown.
  
Freeform Oregon Agate
Agates can be collected in many areas along
the coast of Oregon. The areas around Newport are among the
finest agate hunting areas in the world. Each year the supply
of stone is uncovered by the tides. The years 1998 - 2000
were the best collecting years of probably the last 25 years.
You can still find nice pieces of agate from small 1"
pieces to ones that may weigh 1-3 pounds or even an occasional
trophy of 5 pounds.

Fairburn Agate
These agates were named after a prolific locality
10 miles east of Fairburn, South Dakota, in the southern Black
Hills area. According to Roberts and Rapp (1965), Fairburn
agates occur in a broad elliptical belt extending from Creston
in Pennington County, South Dakota, to near Orella in Sioux
County, Nebraska, with the maximum width approaching 15 miles
near Red Shirt, South Dakota. According to Fritzsch (S.D.
School of Mines and Technology, personal communication, 1993),
the area is more restricted. The Fairburn agate fields cover
thousands of acres of very stony land and most of it is
rugged terrain, well decorated with cactus, weeds, and cedar
trees (Zeitner, 1964).

Western Lake Superior Agate
Lake Superior agates can be found on many Lake
Superior beaches throughout the states of Michigan, Wisconsin,
and Minnesota. Like all agates though, cutting and polishing
them required some special equipment and skill.

Brazillian Agate
The Brazillian agate agates comes from the province
of Minas Gerias which is located in the South American country
of Brazil. Like all agates they have a hardness of 7 and are
full of those beautiful coloured bands.

Turritella Agate
Turritella agates were formed 40-60 Million
years ago in a salt water sea that covered what is now Wyoming
in the Western United States. A snail of the Turritella specie
lived in the shallow waters of the sea. The shell of this
snail had a small, long, tapering spire with many whorls.
The shell material has been completely replaced by agate and
chalcedony while retaining the dramatic whorl pattern.
Laguna Agate
Laguna Agate is generally considered to be the
most colorful banded agate in the world. It is found in a
north-south winding mountain range due south of El Paso, Texas
and east of Mexican Highway 45 in the state of Chihuahua,
Mexico.
Unlike many of the other Mexcian agate deposits
which can be small, the Laguna agate can be found in lots
of sites on the mountain for a distance of 4 miles or more.
Most of these areas are in the top third of
the mountain. Many of the claims do not have roads to them
and have been worked by hand.
