Rarity and Demand

Sapphires from historically significant but now-depleted mines, such as those in Kashmir or certain Burmese locations, become more valuable over time due to their scarcity. As fewer stones from these sources become available, their historical significance as relics of a bygone era of gem mining adds to their allure and market value.
