Yellow jasper is a good candidate. Its not sulfur and I would not bother with a torch or acid. A torch on a silicate will likely have it pop and splinter dangerously for your eyes and acids will have no effect except to burn ya if your not careful with them. I doubt you can scratch it with a knife and from the polish its got a high silica content.... agate~jasper.... sulfide minerals are fairly soft and grainy in appearance. They also don't survive long in a stream environment before breaking up. If your up to it put it in an old sock and just smack it with a hammer *wear safety glasses* and if the resulting pieces are sharp you have a silicate. Otherwise put it in a tumbler
Try poking it with a sharp knife point, if it crumbles/ chips, it's not gold, if it indents like lead, it very well could be gold, if it's very hard to make mark on, it's not gold and could be Jasper/quartz.
You can also to do a streak test, rub it on a piece of dark unglazed ceramic, see what color it leaves on the "ceramic test plate", if it's white it could be sulfur, Jasper/quartz, etc., if it golden yellow, it could gold and time to get it test at a jeweler!
I torched a corner of it for few seconds and it had almost no effect. turned a bit brighter.
the fracture or cleavage is bubblywith no sharp edges... the surface looks soft and has all kinds of nicks and dings in it. has a warm glow to it like no other rock ive scence before. I found it in ca.
Im leaning twards gold ore maybe quartz/gold nugget. I will pick up some nitric acid.
It weighs 6.5 oz. I scraped a piece off with a knife and dropped a bit of muriatic acid on it. It fizzed a bit but there remained a bright yellow spec in the acid. I just need some nitric acid maybe try another jeweler.From this post and your last, it seems that you know that the gold looking portions of this specimen is malleable such as with lead and gold, if this is indeed the case and you have poked it with a knife, done the streak test, if not a white unglazed ceramic surface will work for gold, rub the gold material on the underside of your toilet lid, if it leaves a golden streak, you have passed two tests for it to be gold, skip the nitric acid and take it to a good jeweler and have it tested, this will be easier and cheaper then nitric acid, by having it tested you will know instantly if it's gold, if it is gold I think you have several ounces in that specimen and it appears to be more gold than rock/quartz.
Have you weight it?
