Found this place on Google maps and saw great reviews....
They were TRUE !!
This shop is fantastic and the shop employees are very knowledgeable....Noriko Yumita was a pleasure to work with.
English is spoken and bring your passport to get the Duty Free discount....definitely going back !!

I had the most amazing experience here with Noriko. Their pearls were beautiful and their customer service was excellent.

Great place! Went to a few shops around Ginza and this shop spoke English. Noriko was very helpful, she explained all the diamond sizes, cuts, clarity and color. Diamonds have certificates. Bring your passport if your a foreigner and get it tax free, saving 8%. Allow your self some time, the ring making process can take from 1 to 2 weeks. The ring will be Made in Japan. Highly recommend setting an appointment, as deciding what kind of ring and diamond is time consuming.
