Anse Source d’Argent If you want to know why the Anse Source d’Argent is so popular, try this: go and search for images of beaches. Most of the results will feature the beauty of this gemstone in Seychelles. The beach is pristine and the water is turquoise – almost to the point of absolute perfection in beauty.
