Short and sweet. I like it! :D

Beautiful.

I really, really liked this.
Very well written(:

Wow... this was... brilliant!

I love this!

Wow, loved it. The part abour the shattering glass was so wonderful. I think I'm gonna copy it and put in my night table. (I save pieces of writing I like there)
Congratulations on the amazing job =)

Nicely done! A well-crafted little vignette--the style seems just perfectly suited... Lovely!

Great story. You really captured the feeling of time standing still and all the thoughts that can happen in that short amount of time. I hope that you write about Ron explaining the locket to Hermione sometime. You would do an excellent job of getting into Ron's head and dealing with all of the emotions he felt.

"depressurise"

I think you meant 'depressurize'?

"you have no way out and find yourself on tenterhooks too."

Add a comma before 'too'.

I really like your writing style--not too wordy, and you captured the feeling well. You extended the character's feeling for a long time without coming off as dull, and the juxtaposition between the glass falling and his reaction was well played out. I don't really get why the locket was mentioned, but all in all, this was well-written for a drabble.
