I have for sale a Nice Quality Fossil Opal Rough Parcel from Lightning Ridge Australia. These weigh 105cts in total. They are Crystal Opal, mostly Clear, one Dark base, with Sand cores/or skins. Also Nice Fires in some of them. Not all. There is a Clear Opal shell, good form, no Colour. Also a longer Full shell specimen with Green/Blues. Very Nice. Next 2 thin Skins of Crystal with sand under. Blocky Fires in one, and Green/Blue in the other. Next a Whiter/Milky Opal with a Thin Bar running through. may be a fossil shell, hard to say. Last os the big plant/dark base specimen, slight Blues in that. Collectors parcel.  Thanks for looking.
