Hi ! Thanks for the answer !
Just yesterday, I found that Google Translate could translate Tamil and that I could do "handwriting", so I did write this but he found Taru, he didnt recognized the Ti, but you did ! Thanks !
Going to change the subject to Resolved.
EDIT : Why can't I edit the first post to change the Title ? :x
Since it was written on a piece of jewelry, I think it may be another meaning like Wikipedia says :
Thiru is a word that also means "sacred" or "holy". It is also a Tamil name for the God Mahavishnu, who is called "Thirumaal" (திருமால்), and Goddess Lakshmi, who is called "Thirumagal" (திருமகள்) in Tamil. It is also meant for "wealth", "respect", and "name" in Tamil language.
Is this right ?
If so, it would me more logical for it to mean, in this instance, Holy or Wealth.
On a piece of jewellery it is some kind of "signature", by which the shop from which it was bought would recognise it as their product. If you took that piece to the same shop after some years for selling it back, they would offer a little higher buy back price than others.
