These shells are one of my favourites. I love the colours. A pecten shell which is a type of large scallop shell that naturally come in a wide variety of colours. Here, various coloured pectin shells are hand cut into 6mm Heishi beads. Pecten shells have prominent ridges on one side of the shell, so you will find waves on the pecten Heishi which add character to the beads.  
The shells are undyed the colours are  natural. Ive added daisy spacer beads and fuchsia 4mm swarovsky crystals throughout the bracelet. 
I also have anklets available   

You can choose a heart charm or a starfish
