七月诞生石 · July Birthstone

July 出生的人，现代表通常写 红宝石（Ruby）。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。

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

七月这一栏：两套表都是红宝石；它也是仅次于钻石的第二硬，所以给七月出生的人挑礼物最省事。Ruby on both lists — and the hardest stone after diamond, so a July birthday is easy to shop for.

由铬致色的红；最好的是一种纯净、带点荧光的红Red from chromium; the finest is a pure, slightly fluorescent red

传统联想 · Long associated with

梵语文献称它为宝石之王。欧洲人把它读作生命力与忠诚——都是象征，它从来也只声称是象征。Sanskrit texts called it the king of gems. Europeans read it as vitality and devotion — symbolism, which is all it ever claimed to be.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。传统上中国偏爱的红色石头是南红玛瑙和珊瑚，不是红宝石；红宝石是外来宝石。No classical Chinese role. Historically China's prized red stone was 南红 agate and 珊瑚 coral, not ruby; ruby arrived as an imported gem.

来历 · Where it comes from

红宝石和蓝宝石是同一种矿物——刚玉。红色的刚玉叫红宝石，其余颜色都叫蓝宝石。Ruby and sapphire are the same mineral — corundum. Red corundum is ruby; every other colour is sapphire.

保养 · Care

非常适合日常佩戴。但重击仍会崩，且同样大小颜色不同价钱能差出很多。Excellent for daily wear. It will still chip on a hard blow, and the same stone can vary hugely in price with colour.

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，都是红宝石（Ruby）。The traditional list names the same stone — no disagreement for July.

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.
