I think this is the first time I've seen a jeweled henna. It's gorgeous, although it's probably very painful. Reminds me of the original story "The Little Mermaid," when the grandmother says to the princess that beauty requires pain.
Henna is a tropical scrub which was used by the Egyptians, Arabic and several Asian countries to dye hair and used as traditional body art. In the modern context it's becoming a fashion trend which can be used as permanent and temporary body ink.
