Has the look of old cuff but assure you it is new & a wonderful piece. I have always liked alot of brown matrix in turquoise & this is a good example of that. I don't know...just think it gives it a more earthy look. It is hallmarked with an S & a back slash line? Do not know the artist. the inside measures 5 1/2" with a 1" opening. It is 1 2/16" wide. Fits my 6 1/2" wrist perfect. It is heavy/thick so ajustment not recommended. Weighs 56.9 grams.
