![✨ These earrings feature Lab Grown Sapphires created using the Czochralski Method - a technique that allows crystals to form with remarkable clarity and depth of color. Their rich midnight-blue hue is the result of controlled trace elements and slow, precise crystal pulling, giving each stone an exceptional brilliance. Designed by @gem.adele, crafted to captivate.
