This is the Spring Version of Paul Morelli's Pebble Cuff Bracelet. It has 18k yellow & white gold & 20k pink gold throughout. There are yellow & white diamonds integrated with a great variation of semi-precious stones such as Peridot, Blue Topaz, Pink Tourmaline & Moonstones along with Pink Sapphires & Emeralds. The Pebble Collection was inspired by pebbles sitting below flowing water in a stream in the rear of the designer's cottage in New Hope, Pennsylvania.
