This is a really gorgeous, bracelet from Spanish artist Fransisco Gomez who's usual style is Navajo.  It is all sterling with several stones/shells. The 1 3/4"x 1 2/8" center stone is a robin egg blue turquoise (real pretty). There are a total of 6 orange spiny oyster shell pieces along with two yellow & green stones on the sides. I do not know what stone the yellow & green mix is but it really looks good on this cuff. It is signed like the piece below in the far right. The inside measures 5 3/4" the opening is 1 1/4". I am a 7 to 7 1/2" size & this is big on me. It would fit up to a 8" wrist I would say. The height from top to bottom is 2". Weighs 69.3 grams.
