Hi, I'm Frederick from Brunei & new here. I have found some strange items from the beach (ref attached photos for one of it which I aldy so some polished) and which some ppl said it's Borneo Amber but I found that's not much info or study about it in internet. Definitely it's not agate since it's abit soft (easy to be polished) but harder thn Copal..and it has some kind of scents & more stronger scents if rubbing it. I hv found some of it & their hardest vary... Sound like glass when slightly knock it.. May i know it's an amber or semi fossilized tree resin? Or it's petrified wood with amber? How to justify it?
