What on earth? in Macro #13

Win the liquid author rewards for this post.

#8 was "sugar crystals" won by @sulev with the first correct guess.

This was the hint:

#12 has been won so no roll over there.

This is macro Photography so its something small that is enlarged in the photo.

First correct answer wins all the liquid author rewards for this post... after its paid out.

I'm looking for one words, 6 letters:

this is a _ _ _ _ _ _

If nobody gets it the pot will roll over to the next one (#14)

One shot per account. You don't need to vote or anything (although it may increase the pot)

This is an experiment on gamification of steemit content (non-betting)

I will put up the result a couple of hours after we have a correct entry.
