How can you tell if Japanese pearls are real?

To tell if Japanese pearls are real, first feel their surfaces carefully. Cultured and natural pearls will be slightly gritty, while imitations will usually feel smooth. Next, look at the pearls side by side. Real pearls will show slight variations in shape and size. If your pearls look entirely uniform, they are less likely to be real. A certified appraiser or experienced jeweler can evaluate your pearls if you need further assistance. On 1stDibs, explore a selection of pearl jewelry.
