Q：How to easily distinguish between dyed pearls and undyed pearls？
A：There are several ways to distinguish between dyed pearls and undyed pearls:
-
Color Consistency: Dyed pearls often have an unnaturally uniform color throughout the entire pearl. Undyed pearls may have slight color variations or iridescence due to their natural formation.
-
Surface Inspection: Examine the surface of the pearl closely. Dyed pearls may have irregularities or color concentrations on the surface, indicating dye penetration. Undyed pearls typically have a more natural, uniform appearance.
-
Core Examination: Cut the pearl in half to examine the core. Dyed pearls may have a visible layer of dye near the surface, while undyed pearls will have a consistent, natural core without any added color.
-
Price Comparison: Dyed pearls are generally less valuable than undyed pearls. If the price seems unusually low for a pearl of its size and quality, it may be dyed.
-
Purchase from professional websites: When purchasing pearls, opting to buy from specialized stores or websites with professional staff and offering long-term quality guarantees is a safer choice. These stores or websites typically have higher credibility and provide stricter quality control and assurances. Buying pearls from these sources can offer more protection, as they often provide more comprehensive after-sales services to ensure that you are purchasing genuine natural pearls rather than dyed pearls.
By considering these factors, you can more easily distinguish between dyed pearls and undyed pearls.
