I purchased a smaller version of this from another seller, for my wife for Christmas, but the chain broke after a few months, and she lost it.  She really loves this design, and begged for a new one... I saw this one for a few dollars more, and thought I'd give it a try... sooo glad I did!

The pendant is larger than the previous one, nearly 3/4" width and height (not counting connection to chain).
The back of the pendant is "sparkly" and "faceted", so if you were to wear it reversed, people may think it has hundreds of tiny diamonds on it (at least from a distance).
The detail of the knot is pretty good, not perfect, but better than expected and looks like the picture.
The chain is "standard chain", but heavier than the previous one purchased... so hopefully this one won't get lost!

I agree with other reviews, the chain could be / should be longer... 20" would have been perfect, but it is what it is.

The size of this pendant is perfect... you can see it from a distance very well, and make out details... and it is large enough that even a guy could wear it (on a more masculine chain, that is)... it's not too dainty or girly!
