hello,
Bump..
I was with my stone kicker friend last week the stone it's been identified as (drum roll please..) green calcite. It was identified & matched against a smaller nodule of green calcite & a nodule of blue calcite additional details provided by a student of the scientific study of rocks called petrology, which is an essential component of geology.. Whilst I was chatting I traded (non monetary) & received some nodules of rose quartz, green quartz, smoky quartz, & raw honey calcite tried & tested all shew sparks.
Regards
David
