Just one picture for starters because is extremely time consuming to edit these kind of pictures.
I've uploaded a 100% crop just to see the inner " satelites", 6 of them around a bigger(ish) one. That's the first time for me to see that structure and I have at least 10 years since I started to photograph snow flakes.
They are around 1-1.2mm.
Picture taken with an Olympus macro 38/2.8 hooked on a collapsed Telescopic Auto Tube 65–116. Magnification around 3X

Yep, indeed.
All these crystals are water (mainly, at least), and yet they appear in a stunning variety of forms and details.
What's causing this?

I wish I knew.
Stars are pretty similar in shape and " dendrites".
OTOH, It's the first time since I'm photographing snowflakes that I see grids inside them.

Please, tell us! LOL
My opinion is snowflakes are leftover traces of the liquid to solid state transition layers showing the influence of the hexagonally resonant components of the subtle organizing force.  The same subtle organizing forces driving life and all creation. Held in a static position relative, the forces from the Universe at large swirl around us. (I know nothing of the Science around snowflakes --why hexagonal for example.)

Me neither - that's why I was asking!
For me - as a scientist - the most staggering fact is that those snowflakes are growing symmetrically into the same shape on all six sides, which implies some sort of coordination between the (usually) six "branches" of a snowflake.
That said, crystallisation (at least among chemists) always was considred as a kind of "magical craftsmanship". There were some tricks and slicks, but it largely was an art, not a science. Nevertheless it was essential for the structure elucidation of many important compounds, especially in organic chemistry (X-ray structure analysis).

Here is a different ice crystal:
I stayed 1 hour in the snow at -12C hunting for snowflakes. That's all I got, that's all I've seen. Not a single star shaped, 6 hexagons or branches. Nothing. Only sticks. Checked again couple of hours later with the same result.

Interesting. And what was the temperature when you got the hexagonal crystals? Less cold?
Here where I live - in central Switzerland - it's rarely lower than -10°C, and even rarer to snow at such low temperatures. "Cold snow" (below -6°C maybe), however, is much less sticky and much more of a powder than "warm snow" (= around 0°C or slightly below).

Hexagonal I got them at around -9 C.
I don't think that a 3-4 degrees difference would be that important.
