Vintage Natural Blue Aquamarine Silver Victorian Style Pendant

  
Vintage Victorian Style Aquamarine Silver Pendant. My mother received this gorgeous pendant as a confirmation gift. She was 14 at the time, is 79 now. Which makes this piece 65 yrs old!! She could only tell me that it is silver, not what type of silver it is exactly.

1 1/4" tall (bail included) and 1/2" wide. Pics 2 & 3 are a bit off and 4 & 5 are way off (sorry) and are for scale only!

PIC #1 COMES VERY CLOSE TO WHAT THE STONE LOOKS LIKE IRL!!
