Gems are a general term, among which jadeite and diamonds are the most expensive. . .
I suggest going to the Star Pavilion. . . Because the most striking thing about gemstones is its starlight effect.
(Also known as the Xing Cai effect or the star pattern effect. Under the irradiation of light, the curved convex crystal plane presents the optical phenomenon of four lines, six lines and at most twelve lines of starlight crossing, just like the starlight in the night sky. )
