Don’t buy, gold is wearing off.
Color: Paperclip - Gold, Size: 7 inch, Color: Paperclip - Gold, Size: 7 inch
It’s a nice sturdy bracelet; however, after having had for less than 2 months the gold is wearing off. Not happy. Too late to return. So I would not recommend purchasing.

Do not buy in advance because they won’t size it!
My husband ordered this ring a month ago & gave it to me & it doesn’t fit. I need a bigger size. I took it to a jewelry store to get it larger & they told me they don’t think it’s solid gold. I can’t get it larger! I think if you want to exchange a ring after a month they should honor it for size as I never wore it.

Taller and wider than I expected
Gem Type: Ruby, Ring Size: 6, Gem Type: Ruby, Ring Size: 6
My ring came in with some small scratches on the middle stone. I read in the description that you could receive a stone that is “cloudy” so I am lucky that my stones are free of any cloudy spots. I’m sure it will get some small scratches as I wear it. The ring sits up high on your finger and it’s wide enough to keep your hand from being closed all the way leaving your pinkie sticking out. I tried to capture that in my pictures. Overall I am happy with the ring. I just wish I knew how wide and tall it was before I bought it so I’d know what to expect. The stock photos don’t give any views of the side of the ring.
