💎✨ *Why Do Opals Dry Out?*
Did you know that opals contain water within their unique structure? 💧 Over time, excessive heat or extremely dry conditions can cause moisture loss, increasing the risk of *crazing*—those delicate surface cracks unique to opals. 🔥💎
Handle your precious opals with care and keep their natural beauty shining for generations! 🌈✨
