九月诞生石 · September Birthstone

September 出生的人，现代表通常写 蓝宝石（Sapphire）。下面把两套表、每颗石头的来历与保养，以及它和中国传统的关系都列出来。

September is most often given as Sapphire. Both lists, every alternative, the care notes, and whether the stone has any Chinese tradition — all below.

九月这一栏：两套表都是蓝宝石，属于没有分歧的六个月之一。Sapphire on both lists. One of the six months with no disagreement.

颜色 · Colour

经典是蓝，但蓝宝石就是刚玉——粉、黄、绿、以及橘粉色的帕帕拉恰都有Blue is classic, but sapphire is corundum — it also occurs in pink, yellow, green and padparadscha orange

传统联想 · Long associated with

欧洲传统里蓝色蓝宝石象征忠诚与清醒的判断，这也是它在钻石接棒之前长期是订婚戒主石的原因。Blue sapphire in European tradition stood for faithfulness and clear judgement, which is why it became the standard engagement stone before diamond took over.文化联想，不是功效 · a cultural association, not an effect

在中国的传统里 · In Chinese tradition

在中国古代没有正统位置。但有个细节值得知道：古汉语的「青」兼指蓝和绿，所以古籍里描述的颜色未必是现代人以为的那个。No classical Chinese role — but worth knowing that in old Chinese usage 青 covered both blue and green, so the colour named in old texts is not always what a modern reader assumes.

来历 · Where it comes from

1912 年那张表把蓝宝石定在九月。它和七月的红宝石是同一种矿物——比价的时候这一点很有用。Formalised for September by the 1912 list. It shares its mineral with July's ruby, which is a useful thing to know when comparing prices.

保养 · Care

非常适合日常佩戴，硬度仅次于钻石。Excellent for everyday wear, second only to diamond in hardness.

1912 年之前的传统表 · The older traditional list

比现代表更早的那一版。这一栏的传统表和现代表指的是同一颗石头，没有分歧。

传统表与现代表一致，都是蓝宝石（Sapphire）。The traditional list names the same stone — no disagreement for September.

挑的时候看什么 · What matters when choosing

硬度只说明抗刮，不等于抗砸。本月的石头硬度是 9。硬度低的不适合当每天戴的戒指，但做耳饰、吊坠完全没问题；硬度高的也可能崩口。真正决定磨损的是硬度、韧性、以及你戴着它做什么。

先问是不是处理过的。祖母绿充填、蓝色托帕石辐照、黄水晶加热、绿松石浸胶染色，都是常见且正当的做法——但卖家应当告诉你。不说的才是问题。

两套表挑一个你喜欢的就行。因为两套表都有人用，你完全可以按颜色或预算选，不用被「官方答案」绑住。

Hardness only measures scratch resistance, not toughness. Ask about treatments — filling, irradiation, heating and dyeing are all normal, but they should be disclosed. And choose between the two lists by colour and budget; there is no official answer to be bound by.
