The Port Macquarie couple found a blue 42.13-carat sapphire on the second last day of their stay at 7 Oaks, which is the biggest find ever made by a fossicker at the property.

The sapphire was found in a pile of sapphire wash at the property using sieves, and Peter Black of 7 Oaks said it was an outstanding find.

“The stone is an absolute monster, it isn’t the biggest tone found at 7 Oaks but is certainly the biggest by a fossicking visitor,”

Peter estimated the stone could fetch up to $5000 from a collector or could be cut into two stones by a jeweller.

7 Oaks fossicking ground is on Rickeys Lane off the Swanbrook Rd Inverell.
