Antique Art Deco 10k GOLD Onyx SIGNET Ring Stacker Initial J R Ornate Band VTG

Description

ABOUT:
Lovely antique to Art Deco 10k solid gold onyx stone signet ring with a gold letter J (unless flipped over it is an r?).
This ring is from the early 1900s but it was actually never owned / worn!  I purchased about 15 rings from a woman whose family had owned a jewelry store around the turn of the century (c1900).  The rings had been stored away in their old case for all these years and some of them even had the original price tag still on them.  So while it is a genuine old piece, it actually has no wear to the stone or setting or band - a pretty uncommon find.  The buyer will be its first real owner.
The gold initial really stands out from the onyx.  Fun piece to wear!
SIZE & MEASUREMENTS:
Currently about a size 7.  The onyx is about 7mm by 10mm.  Weighs 3.3 grams
HALLMARKS:
Hallmarked 10k inside the band. It is also marked I of X (like the ring was #1 of 10?).
IMPORTANT CONDITION NOTES:
All my pieces are pre-owned and in estate condition.  But this one was never worn so it is in better than most condition with no real issues to report.  The edges of the shank are blunt for an antique ring since it was never worn to rub away at the gold.  Like new old piece.  However with all my antique pieces I always leave a disclaimer that it is not a mint condition item.  This is as close to it as you can get though I'd say. : )
Thanks so much for looking!
