Product code: Circa 1890 10k gold buying dragons breath opal early victorian ring also 1909 post card
Very pretty unique Antique early Victorian ring some called it jelly opal /Dragons breath has gold flowers around the sides The Stone is large and is dragons breath or Victorian Art glass both unsure. Either way it's stunning ! In the camera flash or if move it in the light flashes different colors and reflects. The ring is 10kt gold or poss some 10k with part of it gold filled this is what I was told by the seller(got many good things from) I tested myself and it does test positive around 10kt (pic test above) it's 7.06 grams. The ring measures around a 7 1/2 but I feel it's closer to 8 as I wear an 8 it wasn't tight. I am pricing it well for age won't move much as I'm gonna keep it for myself buying if it doesn't go around this $ it's truly a nice antique ring. The post card is old with note pretty roses from 1909. Please review all pictures for details condition and size it's in good vintage condition with slight signs of age/ware. Any questions please ask thanks.
