Strait from the source this is what Swarovski has to say of this piece, "The inspiration for the Sea Urchin Round stone comes directly from nature. The sophisticated combination of matte and sparkling surfaces creates the impression of a star shape in the center, reminiscent of a spiny sea urchin in an underwater world. Celebrated filmmaker and marine conservationist Céline Cousteau, granddaughter of the famous French explorer Jacques Cousteau, is the mastermind behind this unique crystal element. As a tribute to the ocean, the Sea Urchin Round Stone makes a powerful ecological statement. Use the Crystal Aurora Borealis and Crystal Bermuda Blue effects to highlight the exceptional appeal of this motif, and combine it with other designs by Céline Cousteau to create bold, nature-oriented looks.
