Any idea what this rock is?

0 votes

This rock has a burnt like very hard blackish/brown exterior and a yellowish interior, it looks like the outside is going rusty in places and when broke it has a wired smell, it is only 5 inches long but very heavy for its size, anyone got any idea what it is?

Weird smell, yellow, maybe a sulpherous compound

Might also be a piece of amber...amber is tree sap or resin and it would have that kind of smell

My money is on the amber. If you ever lit a match you would recognize the smell of sulphur, so by weird small I am thinking resin, like a pine tree being cut down.

Hi not sulfur, it really has a weird smell, and its driving my dog crazy, not sure what the odor is but if i had to match it up with something i would say almost iron smell with a touch of chlorine if that makes any sense.

This is going to sound crazy, but I've heard about something like this before. A couple years ago, some guy was walking along the beach and his dog went crazy when he found this large, heavy yellowish rock. It had a distinct smell and turned out to be some kind of fossilized whale vomit (which is super random). I'm not implying that that is what it is, but it's worth looking into. Here is the link to the website:

I realize how stupid this sounds, but why not check it out...
Hi, not stupid at all and i could make sense, the only thing that is really baffling me is the weight, it is just 5 inches by 3 inches bu 1.5 inches and it weights around 1kg, it was found in the waters around Malta and has dead sea life on the outside but when cleaned is jet black, very strange.
To be honest, I have no experience about ambergris, so my advice now would be to take it in to specialists that know more than I do. Good luck!

Ambergris is very rare and very valuable. It is regurgitated by sperm whales. Beach find normally, oceanic beach. Anywhere else is probably a big fat negative. Amber however is found world wide.
