I found a piece of jewelry... it has JTS engraved on the inside band..What does that mean?

Its a small, Gold (almost looks like something that would dangle from a necklace) and has 5 small diamonds (or cubics im not sure) going around one side of a heart shape. More importantly i would just like to know what JTS means in the realm of the jewelry world or gold in general
Update: Well i figured it was the initials of the manufacturer.. its on the inside of the band, very very very small
--i just got the magnifiying glass out and now also read K14...if it meant 14karat wouldnt it say 14k? im not sure--
I'll post a link with pics if people think its necessary..feedback please!! :)
