Our Quality Control

our mining production ourselves and draw on over 50 years combined
experience in handling rough Sapphires to select the best 2-3% of the Blue
sapphire mined plus the best of the fancy, green, yellow and 'Parti
colour' stones for faceting as Coolamon Sapphire.
We have also spent over 10 years establishing a stable of gem cutters who
gems that have been correctly cut and polished. Our cutters appreciate the
qualities of the
rough and respect the intrinsic value and quality of each stone to deliver
flaw-free, eye clean gems.
The finished gems are again graded by us before the very finest are
offered as Coolamon
Sapphires or Coolamon Blue. This enables is to provide a reliable range of
sizes of gems in various colours. Matched colour sets are our specialty.
You, the jeweller and your clients, can be assured that the gems we supply
as Coolamon Sapphires have been graded and screened by us at every step in
With quality control in force from the rough corundum to the finished gem.

rapidly become a truly rare gemstone and it should be treated with

rarer even than diamonds. Beautiful Queensland gemstones are now
