Stereographs produced from the left and right fields of view of a stereomicroscope. Anaglyphs should be viewed with red and blue glass, stereo pairs should be viewed with the parallel method.
Crystals branches growing from the center column

Crystals consisting of two plains with three branches
Small simple plate and branches in sector form
Skeletal structure at the tip of a branch (frost crystals)

I explored the three-dimensional structure of snow crystals by observing their replicas from various angles. The snow crystals looked a little different from the usual image.
A replica of the plane crystal of double-plate type which has a small circular pattern in the center (left: top view, right: side view)
The unevenness of the crystal surface (replica surface) can be seen by reflecting light.
A replica of a snow crystal of a double-plate type with a small protrusion in the center (left: top view, right: side view).
Through reflected light, a protrusion is visible clearly.
A replica of a dendritic crystal of double plate type (top left), a side view (top right), and an image movie showing the 3D structure (bottom right).
Each branch curves toward the tip. The two plates were connected with a center column.
A replica of a special hexagonal type of snow crystal. I can see the secondary branches protruding from the plate.
A replica of a hexagonal plate of snow crystal. The center has a skeletal structure, and the surface has ridges extending to each vertex of the plate and stepped irregularities.
The bottom of the replica shown above. It has a depression in the center. The outer edge of the depression is hexagonal, and there are no ridges on the surface, which makes it different from the other side.
