Natural raw sapphire nuggets from Australia
a small vial-full
 
When i was traveling in Australia pre-covid, i was on the hunt for opals and other nifty Aussie rocks. A friend of mine had a connection to some folks who liked to go fossiking for sapphires (fossiking is the Aussie term for rummaging around for things of value - especially used with rock-hunting. just in case you were wondering). Anyway, i was able to get a small bagful of these lovely natural sapphire nuggets. 

Fun mix of sizes and colors. I just love them, don't you?
