Necklace has knots evenly spread to make the chain 16 inches. Please check all pictures and read this whole description for important information. I reserve the right to refuse a return in certain circumstances for example. Ring doesn't fit. (All sizes are either in the title or pictures or both.) Item is smaller/bigger than pictured. (All items have a picture of the item next to a ruler with exact measurements down to the mm or inch.) Changed my mind/ Don't like it ect. (These are unacceptable excuses for a return. I am a small business.) Please don't hesitate to message me with any questions.
