This Ethiopian opal contained an interesting inclusion scene consisting of a string of octahedral pyrite crystals and aragonite spheres.
An old blurb from GIA.
Thanks!
I did see the picture you've posted.
Here's a microscopic image of the second opal. Is this dendrite?
dendrites are not 'organic' inclusions so they are not real fossils
they are crystals of manganese which grow the same way like snowflake (and other stuff in nature)
in most cases they form 2D trees but in dendritic agate they are 3D and might look a bit similar to the photo you posted
here is Welo from my collection with unusual inclusions >
*btw. this is stable hydrophane Welo which is different to the 'new' non-hydrophane material
hope this helps
Thanks!
I know what dendrite is.
Here is my image of dendrite in Dominican amber
Your opal is vey nice but I doubt these inclusions are organic. I believe these are minerals, maybe dendrites too.
The inclusions look too uniform to be organic IMO.
