Sterling Silver Green Polished Natural Stone Artisian Tear Drop Necklace

Description

Necklace appears to be Handcrafted by an individua Artist
It looks like maybe it was made in Mexico possibly but is not hall marked by its maker.
Back is stamped 925 for sterling thats about it.
Main Stone color is green with yellowish cream to darker green and black veins running through it.
Round stone is approximately 1 1/4" diameter
Teardrops are approximately 2" long and approximately  5/8" - 3/4" to widest points.
It could use cleaning to the setting. I see uneven polishing or beveling from it being handcrafted.
Also lapidary blade lines to back of stone to indicate someone  cutting it.
One dip in the polished stone to the backside from vein inclusion of the stone that isn't quite flush to surface kinda like you see in natural turquoise stones
I spotted tiny drip of glue to a tear drop stone in front and or light edge chipping to stone in back edge.
Someone has scratched a 5 or letter S to back of round stone. maybe to indicate size of stone?
The closure is a wire hook type.
Definitely a unique handcrafted item by an Artisian.
Does not apoear to be a mass produced item.
