开天窗的翡翠原石如何看

什么是开门子？也称开天窗。因为翡翠原料是被一层皮包裹着，不知其内好坏，故须在原料上切割一片下来以供观察，称为开门子。擦口指在翡翠上用锉刀或砂条把皮擦掉，露出翡翠来，以供观察它的质量。但切口或擦口处，均为翡翠的局部地段，不能说明翡翠的全部，有很大的风险性。从局部开口处来估计推测其内的好坏，是否有绿等，是一门很高的技术。什么是翡翠的场口？场口就是翡翠的产地。缅甸翡翠产地也称矿区或场区，共分六个场区，每个场区又分许多场口。各个场区所产翡翠，外观、质量、颜色都有各自的特点。根据场区场口所翡翠的特殊性，来观察判断这块翡翠是否可赌。场区又分老场区、新场区及新老场区。六个场区分别为：老场区，（也称老坑老厂〉① 怕岗场区，著名场口有灰卡、木那、大谷地、四通卡、帕岗等28个以上场口。② 木坎场区，著名场口有大木坎、雀丙、黄巴等14>个以上场口。③ 南奇场区，著名场口有南奇、莫罕等9个场口。④ 后江场区，著名场口有后江、雷打场、加莫、莫守郭等5>个以上场口。新场区（也称新坑新厂〉⑤ 新场区，著名场口有马萨厂、凯苏、度胃、目乱岗等11个以上场口。新老场区，（也称新老厂〉新老场区，著名场口有龙塘场口等。
