Striking Green Desolation Canyon (?) Thunderegg

Like the previous, this is another specimen with a question mark over it. It closely matches other specimens I have seen identified as Desolation Canyon (including that red flowbanding in the matrix), but I cant be completely sure. The Desolation Canyon area is highly variable and contained several beds after all, so the extremely diverse physical appearance of these stones is not so surprising. Either way - it's a lovely stone with some really nice colours in it!
