Design a sticker

We need a redesign of our 'guarantee stamp' to include the words 'Premium PurityTM'.
Also the phrase 'low-bacterial' is changed to 'low-microbial'.

We are not looking for a copy past of the sticker with the new words, but a redesign.
It can include metallic foil, engravings, bevels etc. - obviously you just have to so how it would look - not produce the finished logo. The shape cen be round, square, triangular - challenge us.

We would like to get more suggestion on a sketch level, than just one finished suggestion.
We will be able to prepare the final version for print inhouse - so again, we are looking for ideas and input, not a finished result.

The aim is to get a sticker that is so nice, that a five, star hotel would put it on their wall in the room.
