SwarovskiHyperbola bangle for women, White, Rhodium plated

What type of metal is under the rhodium plate? Thank you

El ancho de 5.2 Cm de Talla M se refiere al diametro interno?

Does it come in original Swarovski box and packing? How about international warranty? is that available through the Swarovski stores globally?

What are sizes of the Medium and Large ?
