Identifying real pearls with the naked eye can be done by observing several key characteristics. Here are five main points to consider: 1. Texture: Gently rub two pearls against each other. Real pearls have a slightly rough texture, while fake ones feel smooth and slippery. However, it's generally not recommended to rub pearls together, as their surface is thin and delicate, and this could potentially damage them. 2. Drilling: Check the drilling hole. Genuine pearls usually have a clean and clear hole, while fake ones often show pigment buildup around the edges of the hole. 3. Color: Each natural or cultured pearl has a unique color, with slight variations. Fake pearls, on the other hand, tend to have uniform colors. True pearls come in various shades such as white, yellow, and black, especially those developed in France in the 1960s. 4. Temperature: A real pearl feels cool to the touch, whereas fake beads do not. This is due to the natural composition of real pearls, which conduct heat differently than synthetic materials. 5. Shape: Natural pearls are not perfectly round—they have irregular shapes. In contrast, imitation pearls are often manufactured to be very symmetrical and perfectly round. Another important feature is the bonding line. Real pearls have a visible brown line between the mother-of-pearl layer and the outer coating, which can be seen clearly from the direction of the drilled hole. In nucleated cultured pearls, you may notice different bands of transparency when viewed under strong light in a dark environment. These stripes are not present in natural or non-nucleated cultured pearls. Lastly, the surface of real pearls often shows small bumps or irregularities. When rubbed gently, these features become more noticeable, helping to distinguish genuine pearls from imitations.
