I got these grey 8 mm Labadorite on sale. About 50% have flash, and several of them have extremely vibrant and beautiful flash. I can't stop admiring their beauty. They also have good energy. I love shopping with this seller because they have an array of options, from average quality to AAA, affordable pricing, and their products are authentic. I'm always satisfied, and they also ship securely and quickly. Many thanks! 💓
