A probable turquoise ring with possible sterling silver but unable to find 925 on it, and as seen in pictures the inside band is tarnished/silver worn down? ….. (I tried to remove it with tarnex and it improved, but still present). It is only on the inside and does not show when wearing and is smooth and comfortable to wear. It does have weight to it. It is close to 5 1/2 and too small for me…. Very pretty ring....I wished it had fit. I was told it was Silpada, but it definitely is not by the emblem found on the inside.
