This is small snowflake: lesser than 2 millimeters from tip to tip. Despite small size and simple shape, this is beautiful and interesting crystal: it's inner part with curvy lines remind flower, but outer rim with six broad hexagons looks very different.

7 identical RAW photos, taken as fast series, was aligned and averaged to boost signal/noise ratio of final picture. Background: dark gray woolen fabric, diffused light of cloudy sky, Canon Powershot A650is with additional optics Helios 44M-5 (mounted reversely in front of built-in lens as additional magnifier). March 2013, Moscow, Russia.
