Antique 18K White Gold Art Nouveau Garnet Ring Signed M.G.. The ring is in good antique estate condition and ready to wear. The garnet has some noticeable scratches and from underneath you can see it is also cracked. It is a genuine garnet though, not paste. It measures 7.62mmx 7.42mm x 4.4 mm deep so it is about 1.75 carats. The ring is hallmarked 18K M.G. I am not sure who this maker is.
The ring stands about 6mm high off of the finger. The ring is a size 7.5 - 7.75 and weighs a total of 3 grams
