This is a vibrant and absolutely gorgeous blue rhinestone tennis bracelet. Baguette and emerald cut shaped stones are prong set in a bright rhodium plated metal. The stones are so sparkly. I believe these rhinestones are what is called Alexandrite stones because they change color a bit depending if they are in sunlight or various kinds of artificial light. They are a stronger robin's blue in sunlight, and in some indoor lighting are a truer blue and can also turn a more pale lavender.
