Simple concretion, alan. Common in any sandstone formation.

Hi all some more photos of my little stone showing the proper colour which is very dark and after looking very close colour is like a greenish /black matt and after checking up on loose sand and sand concretions I find the grains in my stone are very very different and are only green yellow and orange and some are splintered and fractured also stone is covered in metal lots of it among black material, no rust and good click to magnet, all is revealed when you look closer through lit up microscope, original pics of stone look very yellow as it was taken in bright sunlight which made the stone reflect brightly, the crystal grains have depth to them and I believe would sparkle if stone was sliced, don't look like any sand grains I've seen not that I know what the stone is,grains surrounded by black material that is full of metal, metal also looks to be interlocked with the grains, will get it checked

What's your question? This is a quartz conglomerate weathered smooth... Use a wet saw and cut it in half it you want...

Think that's what I should do, yeh you could be right I never thought of quartz but where does all the metal come from, I've found quite a few natural rocks that contain iron and I didn't think there was much natural iron on earthrocks and non are meteorites as of yet, so you explain quartz then you can explain the iron !!

It's not a quartz it's olivine. You can find it in basalt (with iron) or gabbro. All finds are from Earth

Hello art blade I thought olivine but who knows really but I do know its not sand, it was found about qtr mile inland from sea between dunes and golf course and considering it was near sea there is no rust and all metal is black untill filed and it file's up quite nice and I don't really want to cut it to be honest, picture before last has a dog hiding in a crystal can you see it, maybe the nahkla dog resting place ha ha kidding of course,I will have it looked at, they must hate me at the museum ha
