Necklace - Makers Mark Identification

by Alev Turoy

Hi, I recently purchased this beautiful necklace from a charity shop and was surprised to find out that it is real silver and very well made. I have been trying to identify the makers mark with no results. I am uploading a pic of the item, unfortunately the hallmarks are too small but both necklace and chain have the same mark 925 with what looks like the letters TS above the 925 mark. Any info including possible value would be appreciated.Thank you!
