Value: Natural, untreated gemstones tend to be of higher value. Their rarity and purity contribute to their allure.
Inclusions: Most natural gemstones contain inclusions—tiny imperfections within the stone. These inclusions are like fingerprints, unique to each gem. They help gemologists verify authenticity.
Enhancements: Some gemstones undergo treatments to enhance color or clarity. Knowing whether a gem has been treated is crucial for informed buying decisions.
