[QUOTE="Salinger, post: 462257, member: 14312"] Thanks Megsy and Pat! As for hardness, I can't put a mark in it with a coin so I broke out a pocket knife and managed to put a nice blunt spot on the knife but no mark left on the surface of the rock. I tried to scratch it with the tip of the blade, but it didn't leave a mark at all. I could try a streak test, but the hardness of the rock leads me to believe that it wouldn't leave anything behind. Dad reckoned it's topaz, but he was also prone to telling a whale of a tale, so it was always best to remain skeptical when he'd start up. ;) He left behind some interesting bits and pieces. Lots of small sapphires and garnets (I think), a few chunks of the stone I posted above all of a similar size. And quite a few points of black quartz (I think), one of which I have with me: [img]https://www.prospectingaustralia.com/forum/img/member-images/14312/1546327837_7.jpg[/img] [/QUOTE]
