This includes four opal posters
-One is a amazing opal mosaic made up of small lightning ridge crystals and this is featured in the well known opal writers book Len cram
-A stunning yowah specimen with blue green precious opal filling the voids up.
-A large chunky rough-1375 cts- which is a gamble to cut but a great specimen-it could be cut a number of ways.
-Crystal rough specimen called a septarian formation where the precious opal has seeped in to cracks and made this unusual heart looking shape.
