The incredibly unique part about Glow of the Caribbean jewelry is that you truly get to experience it. Their patented technology creates a glow that radiates out of each piece of jewelry for up to 8 hours at night. Just wear your jewelry out in the sun, then watch it come to life at night. The more sun the longer it glows. Glow of the Caribbean jewelry is made of natural high-quality gemstones and set in .925 Sterling Silver. Each piece comes with a full 3-year manufacturer’s warranty.
