Red or Pink corundum is called Ruby.

"Coolamon Blue"


It is a great pleasure to introduce gems that will be classed as Coolamon Blue. Among the many gems we see there are a select few which have that intangible something that makes them extraordinary. Often it is obvious that there is something special about a piece of sapphire even when it is in its rough form. These stones are selected  when the rough is being graded and are sent to specialist gem cutters to reveal their true beauty.

Be assured that any gems graded as Coolamon Blue are gems of remarkable character, colour, and "Fire"
