    Hi Thomas

     

    Hard to say from your current photos. Please take photos in overcast natural daylight without flash (with a scale again)

     

    We get queries worldwide - please say exactly where your specimen came from

     

    Please estimate the Density of the specimen by:

         1) Weighing to nearest gram

         2) Estimate volume by displacement of water in measuring jug to nearest ml/cc

     

    Many thanks

    The Density of c.2.5 is typical for many rocks I'm afraid.  

     

    The photos show a featureless black item which could be man-made or basalt among other options.

    Is that a UK £2 coin?

     

    Suggest you Google Geology Vancouver - You may like to download some articles and maps

     

    The area will have been glaciated during the Ice Ages so the pebble could have travelled a long way.
