I take a beautiful, but highly flawed 297 carat chunk of Australian opal and cut it. I also used two other chunks of Australian opal (total weight = 1000 carats!) to make two opal arrowheads.
The 297 ct opal was difficult because it was covered with sand (matrix) and had a number of cracks. I ended up making 5 cabochons (total weight of 145 carats), including one that very closely resembles a fossil (opalized) clam.
