Lanvin for H&M necklace with intricate flowera

Lanvin made a special designer collection for H&M in 2010. This necklace has never been worn. Would be beautiful for a bridal shower in the spring. See the matching bracelet in my closet. A very dark, antiqued chain with fake pearls strand alongside. One large flower on the right and two smaller ones on the left. The flowers are made of beads and large sequins. They are iridescent. 2 are pale pink, the other is a shade of green.
