[QUOTE="Fossil_phile18, post: 433265, member: 13341"] Could be opalised wood. You'd have to sandblast away the hard white exterior --- veryvery carefully --- so as not to damage any ridges etc. Opalised bones have a typically smooth exterior surface, while opalised wood usually shows bark striations, sometimes knotholes, even when crushed flat and out of shape.[img]https://www.prospectingaustralia.com/forum/img/member-images/13341/1534471029_xbm_allawah_circa_2015.jpg[/img] This piece is from Allawah field, mined in 2016 from memory, showing very bright burnt-orange gem colour and the kinds of exterior striations described above.
