I'm doing a new page on my website for color charts with Swarovski stones and also for the freshwater pearls I have available. I should be ready with this new addition shortly.
The charts are intended to provide information about crystal colors for custom orders. If you see a piece you like, but you'd prefer another color, you can see what's available.
As always, you can't be absolutely sure about the colors you see on your monitor, but it will give you an idea. The pearls come and go and I can't always get more. I can order any of the Swarovski items.
