Yes, I know, we're in December! It's been rather busy around here so our October birthstones didn't get shared until the end of November, and I'm only just now catching up on blog updating. Did you know there's this big thing called Christmas coming up? Seems to happen every year....
OK. birthstones. The birthstones for October are opal and tourmaline. Both Cindy and Nola chose to focus on opal.
Cindy created a double page with a fold out, with lots of interesting facts about opals, including a photo of an opal ring worn by Elvis! She experimented with using metallic foils on glue to create opalescent colour on her page.
Nola became interested in the geology of opals. She discovered that there are many fossils made out of opal, as the liquid silica from which they form gets into hollows where organic material used to be.
The most amazing fossil she found is the Addyman Plesiosaur. This is an opalised skeleton of an ancient animal, which was found at Andamooka in 1968 and is currently on display at the Museum of South Australia in Adelaide .
Lots of opalised fossils of plants and animals have been found in Australia, including remains of a large ancestor of the modern platypus called Sterepodon.
We'll show you the rest of our birthstones next year.
For at least the first half of 2015, our chosen theme is Trees.
