Where can I customize the rings of the diamond ring in Xi'an?

There is a stop in the middle of the South Gate and Heping Gate. There is an alley on the south side of the road. Take a little to detect gemstone in the south of the road. On the second floor, there is a store for gemstone rings on the second floor. You can go to see it. If you are not clear, you can ask the old lady nearby. You can find a little bit in the past. If you see what you like, you can take a picture, he can make it over there
