The most affordable and secure thing is that you can buy it through the diamond experience store. Hangzhou is one of the cities with the most concentrated diamond experience stores. You can choose many brands, such as Diamond Bird, Koran, Nine Diamonds, Zachary, Dacheng Diamonds and so on. Experience stores all adopt the mode of combining online shopping with physical store experience. Bird and Koran, two famous brands, are now more expensive than other brands.

Last year, Alos Jewelry set up a new Diamond Caibao Experience Center in Platinum Xuan Yue near the Avenue of Stars in Binjiang District, Hangzhou. It has GIA international authority certificate, 3EX perfect diamond cutting, and even customized high-end jewelry from Cartier and Tiffany. If the landlord happens to be nearby, you can visit, ask and try it on.
