Yes, it is very recognizable (the insect inside helps, no doubt).

You don't use Google? My first try many reference photos:

As you see, the colors vary from a dark orange to yellow. I suppose
there are many kinds of amber out there.

The table on the lab of a naturalist?

Same room but with a different lighting.
Same piece of amber but the surface is less rough, I'm
not sure if the polishing is an improvement, I also do like
the more "weathered" version. The antialiasing settings
are this time quite poor 'cause I was so impatient.
The shape (its just a blob) needs also some work.

To make you something believe is all raytracing is about, isn't it?

A very old piece as found on the Baltic shores. Wow. Phantastic.
Thanks a lot and it's nice to hear that my virtual piece as done from
my memories has something to do with the real thing.

Well, you know, most of the things I have learned from looking
at some of your sources. Especially the way you did create the
micro-surface-normals in your nuts&bolts scene. It took a while
'till I did understand what the heck you where doing there but
meanwhile I really do prefer this way (compared e.g. to large
scaled normals for blurred reflections) because it gives you a
very powerful and precise control on the appearance of the
surface. Was this technique (so to say) invented by you?
> You don't use Google? My first try many reference photos:
Ahem, silly me, I did not use the image search and found just
numerous technical/geographical/scientifical pages. But at least
I got the IOR from there.
> The table on the lab of a naturalist?
Hmm, one more room to create. We will see.

Real neat thing. The bug there. And the amber. I'm leaning toward it
appearing as a glob of very cold honey though. I've been told, and read,
that there are many kinds of amber; fossilized and prehistoric or not aged
enough to be truly fossilized. I don't think it would be easy to render one
of these based on photographs alone and it would be better having a piece in
person. The pictures I've seen typically look like the colors are probably
not always accurate.

Surely hundreds of pov users tried that before... I just have done my
own attempt, with decent results for some situations, but only to find
that "surface microstructures" are something too hard to simulate with
micro-normals, or even with "real" micro-displacememnt (for example with
isosurfaces or fine meshes), mainly because you must use a really big
amount of samples per pixel.

A close-up of the work table will be enough (a view similar to the
test scene), perhaps showing just one wall and other amber pieces, some
with strange/uknown insetcs.

The color in this, second image is much better. It looks also looks better
with this surface, because it explains the regular form. You should try to
make it a little milky at some places, maybe some random areas filled with
less transparent media would so it.

That is just excellent. What you have there is a piece that has
only been 'final' polished. There are two phases to polishing, 1)
'Roughing' - takes out those surface flaws, and 2) 'Final' - produces
a mirror-like finish. This piece has only been 'Final' polished, which
is how it should be with a bug in it. :)
I'd like to see it in a silver ring, pendant or brooch... ;)
