五月诞生石 · May Birthstone

May 出生的人，现代表通常写 祖母绿（Emerald）。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。

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

五月这一栏：两套表都是祖母绿，属于没有分歧的六个月之一。Emerald on both lists. One of the six months with no disagreement.

传统联想 · Long associated with

绿色代表新生与春天，使祖母绿自古就是「重生」的象征——埃及的祖母绿矿有三千多年历史。这是文化象征，不承诺任何结果。Green as renewal and spring has made emerald a symbol of rebirth since antiquity — Egyptian emerald mines are over 3,000 years old. That is cultural symbolism, not a promise of anything.文化联想，不是功效 · a cultural association, not an effect

在中国的传统里 · In Chinese tradition

「祖母绿」这个名字见于明代的本草类文献；它是音译名，不是中国本土宝石，背后没有中国式玉文化那套传统。The Chinese name 祖母绿 appears in Ming-dynasty materia medica literature; it is a transliteration, not a native Chinese stone. There is no Chinese jade-style tradition behind it.

来历 · Where it comes from

今天市面上绝大多数祖母绿都做过裂隙充填，用来盖住表面的内含物——这是被行业接受、且通常要披露的处理，不算瑕疵。Almost every emerald on the market today has been fracture-filled to hide surface-reaching inclusions — an accepted and normally disclosed treatment, not a defect.

保养 · Care

够韧但不耐折腾：别用蒸汽、别骤冷骤热、别用超声波清洗——会把处理过的充填物震出来。Tough but not gentle: avoid steam cleaning, sudden heat, and ultrasonic cleaners, which can drive out the filler used in treated stones.

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，都是祖母绿（Emerald）。The traditional list names the same stone — no disagreement for May.

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 7.5 – 8。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.
