Australia supplies some 70% of the world's sapphire.
The above sapphire is cut using the very best lapidary machines. The cut is superb, not like so many from Thailand and Ceylon, where girls trained from as young as 6, cut stones by the method called jampeg, literally holding the rough attached to a stick and then cut each of the facets by eye judging the angle at which they must hold their hand. It is impossible for them to get the best lustre from an imperfect flat facet surface, and the points where each of the facets should meet exactly to form a sharp point, are always slightly off. Much of the stone sold out of Bangkok is bought from Australia and sold as Thai gems.
Using this method of cutting, the cutters can churn out a dozen cut stones an hour, where a cutter using a lapidary machine which finely calibrates the angles for each facet and polishes each surface perfectly flat, could be classed as very skillful if they completed 8 stones in a day. The labour cost goes up, but so does the quality of the finished gemstone.
So, be cautious where you buy cut gemstones, when in doubt, buy Australian.
