COLANCOLAN bracelet made with natural stones I believe the stones are tiger eye and lava stone. I thought it would be a bit larger, but it's a very stylish, small design, and it's not quite my style, so I'm selling it. The stone sizes are: 5mm diameter for the multi-faceted spheres 4x4mm for the connecting cylindrical stones 2mm diameter brass spheres filling the gaps It's for those who want to wear something stylish and understated.
