Quality Lightning Ridge Seam Opal Rough Stone 25cts Multicolours 2 Sections

I have for sale a very nice Rough Lightning Ridge Opal stone from Australia. This one weighs 25cts and is 22x18x11mm. It has a superb Crystal Bar in the top with multicolour solid fires. Thin Sand skin on top and wavy Grey Potch under it. The potch divides that from a Whiter Opal section with thin bars through it. Pinks/Greens. 2 Totally different stones in one.  Great collectors piece. Maybe cut that top bar and make a ring. Thanks for looking.
