I just looked up S&R Designs and the collection is made out of sterling and is mass produced. I own a couple pieces from Kimberly McDonald and could never imagine comparing her line to this fake garbage.
Geode & druzy are not expensive, you are definitely paying for the designer name, diamonds and to-the-moment demand for the look.
The bracelet is gorgeous but her line is very expensive. I would suggest googling S&R Designs and see if there's a retailer in your area that carries their line. It's also quite beautiful, quality A++, still on the pricey side but nearly as high as K. McDonald.
