Why is the Goddess Alliance so expensive?

This is the latest activity screenshot, which I believe all the players who are still playing know.

Slightly calculate the strongest gem in the ideal.

One piece of equipment has 5 holes, one person has 6 pieces of equipment, and five people need to play 150.

A 9-grade gem 13920 diamond in the picture is equivalent to 1392 RMB (the minimum discount is not discussed).

It costs 208,800 RMB to fill all the gems of this grade.

At present, diamonds are more than 20 thousand a carat?

Equipment made of 10 carat diamond

Well, a web game wants to throw in the strongest gem. /kloc-Can a 0/0 carat diamond cost nothing?
