GREAT news! My friends at Harman (one of my crystal distributors) created this fabulous chart of Preciosa vs. Swarovski color equivalents, which y’all have been asking for!
The first color listed is the Swarovski color. The second color listed is the Preciosa equivalent. If there’s no second color listed, there’s no current Preciosa color that matches up well with it.
Please note that the colors are often not 100% identical. For instance, I know that the Preciosa Tanzanite is a little darker than the Swarovski Tanzanite.
