I am not sure if you joined the opal live dig, but apart from a few technical issues (ended up with three separate sessions!), it was a lot of fun.
Hosts Renee and Dan did all of the work while Steve Davis provided the light entertainment. Some opal was dug up live, including a few opal shells. The auctions were well-supported, even if lag beat a few bidders!
You can still catch the feeds here on the Unearthed Australian Opal Facebook page.
