宝石加工设备及检测仪器
切割台上的每一件物品都是由某人制造的,其中大多数来自从事这一行已有数十年之久的小型企业。本记录了各项产品的制造者:用于切割和抛光的机器、用于检测成品的仪器,以及在任何人动手之前就用于设计宝石的软件。
我们不评测设备,也不对其进行排名。 每条记录均摘自制造商的官方网站,并注明了来源页面及查阅日期。此处没有联盟链接,也没有人付费以换取收录。若某知名品牌已停止经营,记录中会明确标注,因为这通常是您最需要了解的信息。

了解宝石切割工艺和检测方法的买家,看待经销商的商品描述时会有不同的解读。这里使用的仪器与实验室所用的完全相同,只是规模较小;了解手持检测仪能检测什么、不能检测什么,其价值不亚于知道报告是由哪家实验室出具的。
