Can anybody help identifying this rock please?

+1 vote

The rock weighs 618 grams, water test - 500ml start, 590ml emursed. Streak test -white. Scratch glass but not visa versa. Natural British Museum said they could not identify it but possibly could be cassiterite.

Sorry, can't see the stone. Where did you find it? Did you try taking it to the nearest rock shop or club to see if someone else can help? So far we have a rock weighing just over a pound whick displaces 90 ml. of water which streak tests white and scratches glass. So I can tell you it is hard and heavy for its size.

619 grams divided by 90 cm= 6.87 grams per cubic centimeters.

Hiya sorry, I'm struggling to upload my photos, I'm obviously doing something wrong. The rock was found in Darlington County Durham dug up near a pond 15 years ago. A magnet does not stick to it. Can you advise me how to upload my pics, I would like you to see them. Thanks
