Nice Sliced/Matching Koroit Opal Set 413.5cts Gemmy Congolmerate/Nut Material Qld Au

I have for sale a very nice pair of Matching Koroit Conglomerate/Nut Opal Slices. These 2 rough pieces together weigh 413.5cts in total. They are 68x54x8mm and 68x54x10mm, .Room to rub down the skin on the thicker one..  One is singles sided, some Fires/Crystal showing through the skin, the other double sided pattern. They both have lots of Blue/Green Fires mixed into the patterns, some Pools of White/Milky/Crystal Opal in the faces aswell. Very Nice and interesting specimens, or cut some Unique and Colourful pendants from them. Thanks for looking,.,.
