Bully Creek Opal Thunderegg

So this is a Bully Creek egg . . . a simpler and more clear-cut specimen than the previous, anyway. The centre is common opal in the characteristic Bully Creek greeny-gold. All in all, it is a quiet and subtle beauty, this little egg.

Size: 2 1/4"w x 2 1/4"h x 1 1/8"d.
