Very pretty ring and it's in terrific condition I don't know anything other than what I was told when I bought it, and I have no verification or proof of what it actually is made of 1. stamped Titanium on the inside, [but IDK what the actual metal of the ring is] 2. Told the stone is cubic zirconia [but again no proof this is true] 3. Police/cop Thin Blue Line" flag print around the band [this part I know is what it is: it's the dark blue and black USA flag print with the meaning "Thin Blue Line" for support of US law enforcement] ~~Guessing on the size: 4 or 4.5 I am a solid size 5 on the finger I have it on in the picture, and I can't get it further than my second knuckle. (I was told it was a size 5 and that's why I bought it, but it's definetely not a size 5, and is smaller than a 5.) ~~Guessing on stone size: I have other rings with stones that are 1 carat (but are round). This one looks to be about 2 carats, but I am just guessing and don't have a way to size it.
