给大家普及常识性的工艺问题，不要错误误解戒指什么都可以修改的。满怀希望跑个几百公里到省城找金店帮你改尺寸和大小，结果店家说改不了，那不是实在有点冤。可以大致这样统一理解：

　　1.单头钻石戒指：大圈口调节小圈口就更方便容易，直接切割调节合适圈口焊接即可。如果圈口加大码数太高，就会容易变形，操作起来很麻烦，花去的时间还不如重新定制戒指圈。

　　2.密钉镶钻石（圈戒指）：款式已经定型，无从下手，切割哪儿都会伤到整体型，这类型款式一定在购买定制之前要考虑后期改手寸的问题，基本改是无解。

　　注解：改圈口对钻石本身没什么影响（单头戒一般在戒指底部进行）大钻石款一般拆卸钻石直接底部改尺寸即可（如果是真的钻石可以不用拆，切割直接焊接圈口，抛光重新电镀即可，对于翡翠类就必须要拆卸重新电镀，与材质有一定的关系）
