Well I'm a total novice... I see what looks like a pretty lustre and orient, and some lovely overtones....
But I see a strand poorly matched for overtone, irregular shapes and blemishes, and in the upper left of one photo it looks like they are not strung so well.
Value? Sorry, no idea. I paid around the same several years ago for a strand and studs a little larger than these, not as shiny, but they were far rounder and with few visible blemishes.
