Edwardian Bracelet Open Textured Rope Links with Eleven Diamonds yg over ss Signed "Lj" with * over j

My Great Aunt left me a number of antique and vintage jewelry pieces. Several turned out to be "fine" jewelry worth quite a bit of money. This bracelet has completely stumped me. I can find little to no information about the maker's signature marking "Lj;" although, I have been able to locate several other pieces for sale bearing this same distinctive marking. The price range for these pieces is $425-1500. 

My Aunt told me that the bracelet is Sterling Silver with a Yellow Gold overlay, but I cannot find a hallmark. She is positive that the eleven stones are diamonds. Including the clasp, the bracelet is 7.5" long and just under 1/4" wide. The "Lj" marking is on the backside of the clasp. I have included a number of pictures.

I have become almost obsessed with trying to figure out who/what "Lj" was...any information about this marking would be greatly appreciated...in addition to information regarding the value/appraisal of the bracelet.
