I am Taiwanese. My friend gave me a crown ring bought from umu the other day,and I felt it beautiful and delicate, so I browsed umu's homepage to see more jewelry to buy. When I saw this K18PG ring, I thought it worthy to buy. Although it took umu's staff much time to deal with my order, he was very nice and helpful. In other words, the service and correspondence were perfect! Of course, the K18PG ring is good , and it satisfies me and meets my need.
