I had a nice time at Sophia Chen on the second floor, she had real pearls for descents prices, they are not top quality but good enough. To give an idea of the prices I bought a long necklace for 100, simple earrings for 20 yen. You can get cheaper if you go for the standard colours like white. Just don’t forget to negotiate the price, actually they expect you to do so. My advice, don’t buy on the ground floor, that’s where all the pricy shops are, and the third floor is where the majority of tourists traps are. 😁
