Ilakaka is a small town in the south west of Madagascar along the R7 national route towards [[Tulear]]. Ilakaka is a sapphire boom town that has grown from less than 50 residents the 90s to
about 30,000 today. Since 2008 most sapphire stones in the world originate from this region .
Directly north of the road lies [[Isalo National Park]], which likely has large deposits of sapphires, but the area is nature protected where mining is not permitted.
There are various other smaller sapphire towns along the road south.
