We don't really do that here. I suggest taking it to an appraiser for a definitive answer. You can always looks around the internet selling platforms for comparisons.

This is not Mikimoto, who had M stamped in the oystershell, and also marked k14, not 15ct, The wierd thing in the Platm which alomost looks like it is trying to say it is platinum, but it is such a coarse mark. worth testing for the metal, as sometimes two types of metals are used on one piece of jeweley.
