Identifying 925 Jewelry Markings: Help with 'JAK'?

Question
I have a necklace that has 5 filagree flowers, the one in the middle being the biggest. The chain is approx 1/2" size filagree bars no wider than a hemming pin. These bars are connected with a loop. The "U" clasp at the end is the area marked:

925
JAH     or

925
JAK     or possibly

925
JAM

Would you be able to help identify, or at least give me some suggestions as to where I might be able to look this up myself.
Thank you for all your time and effort.

Answer
Hello Sharon - You don't say whether the jewelry is vintage or contemporary.  I was unable to find any of the marks in my vintage jewelry references but all three are represented on the Etsy Website as makers of contemporary jewelry including sterling. You might want to check them out at the following url..  Just click on the url or copy and paste into your browser address field. Hope this helps !
