Alain Tessier signed designer ring shops 1975 vintage blue Grey moonstone smokey blue gray oval stone set in silver propped up raised stone unique

Designer ring made in the 70's
This ring was my Aunts
Signed Alain Tessier 1975
Super unique ring
I don't see a Sterling silver stamp on it
Size 6.25 (sets just over the size 6 mark on my ring wand measuring tool
I am no expert so I don't know what the stone is but my best guess is moonstone
It is ashy blue gray
This ring is so beautiful
The oval stone setting is is 1" by 1/4"
The ring stands 1 1/4" tall so it is raised away from finger quite a bit which makes it unique
nice used condition some super soft scratches
