Origin of this Opal


Queensland  is the only place in the world as far as we can tell, where boulder opal is found.


Boulder opals vary between small ‘nuts’ found in Yowah and Koroit to the south of the state.


Larger boulders with veins of opal range from Quilpie in the south to Winton area in the north.

Boulder opal pendant description:

Very large boulder opal ‘nut’ from the Koroit field in western Queensland Australia. Notice the ‘eye’ of opal in the middle of the piece with surrounding circular show of colors.    

Size: 54×30 mm or over 2 inches from top to bottom. Totally unique pendant. Only one like this in the world.

Boulder opal is becoming a very sought after gemstone for use in rings as well as pendants and all other types of opal jewelry.

Years ago, unless the full color of a stone was observed, not much notice was taken of the other variations in patterns and shapes existing in the boulder opal ironstone associated with Koroit opal.

Now however dealers and customers are getting to know the amazing variety of these patterns and are seeking this as much or even more than the opal by itself.
