The Mocca Siam rhinestones I received are just so beautiful. They are very unique, compared to any other rhinestone. It's hard to explain what I mean by that. They just have this gorgeous color to them. They don't sparkle as much as some of the other rhinestones, but something about them makes them just as beautiful. The whole Mocca collection is something you really need to look at, and consider purchasing. It was so difficult for me to pick just one color. I do plan on buying other colors in this collection, when I can afford it. But I truly recommend these rhinestones.
