This item is a set. The set has one necklace, one tennis bracelet and a pair of pierced, post type earrings.
The Rhinestones are a blue green in color, sometimes more blue than green depending upon how the light is hitting them. The Rhinestones are set, not glued, but set into a silver tone box setting. I am not sure what metal this is just that it is a silver tone.
The necklace measures approximately 16 inches from clasp to clasp closure.
The bracelet measures approximately 7 1/2 inches from clasp to clasp closure.
The earrings measure approximately 1 1/2 inches in length and are a post type earring.
