thankyou for the question and it is no bother at all.
Sadly a no on all fronts.
The charm is not hallmarked and not stamped.
I shall put our FAQ on hallmarking below.
3mm is pretty big so unfortunately no, the clip will not open that wide.
Most people find that the charm will fit a standard Thomas Sabo bracelet as the clip is a 9mm, which is the length of clip.
I hope the above makes some sense but if we can help futher then please let us know
Kind regards Simon
The charm is available on ebay under the following link
or on our website
********** FAQ START HALLMARKING ************************
** Please note the below is based on UK (English) Law and may not be the same in your own country **

Some items are exempt from hallmarking.
To learn more about HALLMARKING visit www.theassayoffice.co.uk as a start.
If an item is under these weights they DONT have to be hallmarked.
1 gram for gold, 0.5 grams for platinum and 7.78 grams for silver.
The manufacturers dont tend to unless they have to as it costs extra money and takes extra time.
Although the items maybe exempt from hallmarking they still have to be as described otherwise this breaks the trades description act and the UK law
Eg you cannot describe an item as 9 carat gold when it is actually gold plated or you cant describe an item as sterling silver when it is 800 standard silver.
All the suppliers we deal with are very particular about hallmarking when needed, as they dont want to be breaking the law. Mistakes do sometimes happen but due to the legal implications this is VERY rare.
The item still has to be as described.
If an item is described as Silver it has to be at least 800 parts of pure silver per 1000 parts
If an item is described as Sterling Silver it has to be at least 925 parts of pure silver per 1000 parts
If an item is described as Britannia Silver it has to be at least 958 parts of pure silver per 1000 parts
There is also an extra mark 999 which is for 999 parts of pure silver per 1000 parts
There are other exemptions but this can be very complex. For more information about English hallmarks you can start with the Birmingham assay office www.theassayoffice.co.uk

********** FAQ END HALLMARKING ************************
Is the charm hallmarked? And will the clip attach to a 3mm wide bracelet? (There is a stopper at each end just over 4mm wide)
It isn’t obvious from the photos so I am sorry to bother you
