必须马上调整角度。
细节，决定宝石的品质。

在切割之前，
必须先把宝石对准中心。
一点点偏差，
后面就很难修。
Before cutting,
the stone must be perfectly centered.
Small error now = big problem later.

这颗碧玺没有明显内含物，
但表面有瑕疵。
切错设计，整颗石头都会浪费。
所以我选择祖母绿切工，
尽量保重量，也避开问题区。
No big inclusions,
but there is a surface flaw.
Wrong design = wasted stone.
So I chose emerald cut
to save weight and avoid the weak area.
