First off, it appears to have been hand-worked or melted on top of something man-made so I'm not saying it's a natural nugget. On the one side there appears to be an unnaturally flat area and two perpendicular lines. That being said the rest of the "nugget" looks somewhat natural with a very interesting fine "crystalline" grain structure on some of the surface. ( I wish my camera was better) I was using a whites MXT and it gave a solid 80 VDI, in the dime range. It's about 1-1/4' L. x 5/8" W. x 5/8" thk. approx. It is heavy for it's size. When polished it's a brownish/ grey/green. Mostly brown. It was found about 4" down right beneath an old avocado tree. Any guesses ? Thanks.
