尚未切割的钻石是什么样的?

Diamonds Uncut

《元素周期表》频道
They’re going to let me touch it with my hands,
工作人员允许我上手摸一摸
watch carefully
仔细看哦
only time in my life
我这辈子唯一一次机会
I’m going to wash my hands in diamonds.
我要用钻石洗手啦!
We’re now in the chief experts department and
我们现在来到了首席专家部门
they have brought out some really special diamonds for us.
工作人员给我们拿来了一些非常特别的钻石
Brought them out from a vault somewhere
不知是从什么地方的保险库取来的
I’m amazed by them
这些钻石太令我惊讶了
This one here
看看这颗
is the……biggest diamond that is here.
它是这里面最大的一颗
it is 240 carats
足有240克拉
but it’s rather a shapeless lump.
可惜形状不是很规则
But down here
但是这里的几颗
there are some really amazing shapes.
形状就非常惊人了
I never realized
我从未想过
that a diamond when it’s not even cut
即使是未经切割的原石
is a almost perfect octahedron.
也可以有近乎完美的八面体形状
it looks like out of the textbooks
教科书级的八面体
I just can’t believe that nature can make anything quite so beautiful.
我真是不敢相信 自然界能形成如此美丽的东西
If you look down here you can see this one here
接着再看看这颗
is a big yellow. because of an impurity
因为有杂质 所以呈现出明显的黄色
and then you can get some quite strong colors.
还有其他深颜色的
This one here is purple
这颗就是紫色的
and this one is pink.
这颗是粉色的
These ones here have grown into an almost perfect cube.
这颗长成了近乎完美的立方体
This little one is really as far as I can see a perfect cube.
而这颗小的 在我看来就是完美的立方体
And then there’s one that looks like a football.
这里还有一颗长得很像足球
Very important World Cup was here in Russia last year;
去年俄罗斯举办了很重要的世界杯
though I don’t play football myself
不过我不踢足球
and then there is another one that looks like a skull
还有一颗 它看起来像骷髅
and if you turn it over its hollow.
把它转过来 可以看见里面是空的
I think because it dissolved during the geological deposition,
我觉得这部分是在地质沉积过程中溶蚀了
maybe in very high temperature high pressure water that it dissolved.
可能是被高温高压的水溶蚀的
But it’s got a rather strange bowl shape with eyes.
但这使它成为了有眼睛的奇怪碗形
Might be a bit grim having a diamond
如果你戒指上的钻石是骷髅形的
shaped like a skull on your ring.
可能看起来会有点可怕
These ones here.
这里的一些
I think perhaps are the chemically the most interesting.
我觉得从化学角度看是最有意思的
They’re black
这些是黑色的
because they’re a combination of diamonds and also graphite.
因为它们是钻石和石墨结合在一起的
We have a box with 1490 crystals of diamond.
这个盒子里有1490颗钻石
It’s very interesting to me that they’d actually count them so carefully.
我觉得很有意思 因为他们真的仔细数过
You can see
你可以看得出
even these tiny crystals are all octahedral
即使是这么小的晶体 也是八面体形状
and if you look under the microscope,
用显微镜看会更明显
you can see these little octahedra.
很容易就看得出八面体形状
I looked in the microscope
我用显微镜观察过了
not very good in microscopes with my glasses.
尽管带着眼镜看显微镜不太方便
But even I could see that they were really nice and crystalline.
但即便如此 我也看得出是很完美的晶体
This one here is a so-called twin
这个就是所谓的“孪晶”
where two octahedra have grown simultaneously in different directions
两个八面体晶体同时向两个方向生长
so you get a less interesting shape and
就得到了这种中规中矩的形状
at the same time
还有一点让我很惊讶
I was fascinated that in this one there’s a crack
这里面有一条裂纹
down on such a strong material
即使是钻石这样坚硬的东西
but even so sometimes it can crack
有时也会产生裂纹
and then down here
请看这里
is a an interesting crystal
这个是很有意思的晶体
tiny But it has three twins that have grown simultaneously
这是三对孪晶长在一起的小晶簇
so you have six octahedra all close together.
所以这里包含6个八面体
These are the different qualities of the diamonds.
钻石有不同的品质
Some diamonds are clearer nicer shaped crystals than others.
有些钻石杂质更少 形状更完美
And again, they have standards to make sure
他们有一套标准流程
that they classify all of them correctly.
确保可以将钻石正确地分类
Because once you’ve got a big box of them
因为如果你有一大盒钻石
if you’ve made a mistake, you
一旦你分错了一颗
have to sort them all over again.
你就只能重新分一遍了
These diamonds are not completely pure carbon
这些钻石的成份不是纯粹的碳
they contain traces of nitrogen
它们里面含有微量的氮
you can’t see this with the eye,
用肉眼是看不出来的
but you can see it by using a UV light
但用紫外线照一下就看得出了
so Natalia will just put the biggest diamonds onto a UV lamp and
Natalia现在要把最大的钻石放到紫外光灯下
You can see suddenly it gives out blue light.
看到了吧 它马上就发出了蓝色的光
And you can tell that different diamonds fluoresce different amounts and
根据不同的光 就能分辨出不同的钻石种类
occasionally you can get a different type of nitrogen center
有时氮原子中心不同 钻石类型就不同
which instead of being blue, is yellow,
钻石就不会发出蓝光 而是发黄光
so Natalia will show you one now one of the cubic ones.
Natalia会用立方体的那颗演示一下
And you can see it’s a greenish yellow color
你可以看出 这颗就泛着黄绿色的光
again, this is a really nice demonstration of spectroscopy
这是一个示范光谱分析的好例子
and you could analyze it even better looking through a spectrometer
如果用分光仪 可以得到更好的分析结果
to get the precise wavelengths of the emissions.
利用分光仪能得到更精确的吸收波长
So here you can see there’s a nice blue glowing octahedron.
这是一个完美的发出蓝光的八面体
Can we try the pink diamond?
我们能用粉钻试试吗?
You can see that one doesn’t fluoresce at all.
你可以看到 这个完全不发荧光
So it probably doesn’t have any nitrogen centers in it
所以这颗里面可能没有任何氮原子中心
or at least none that will absorb.
或至少没有可以吸收紫外光的氮原子中心
But again, this is a nice way of categorizing the different diamonds
这是一个对钻石进行分类的好方法
so that you learn more about their structure,
这样我们对它们的结构和化学性质
learn more about their chemistry.
可以有更深入的了解
Let’s try the pink diamond as well.
我们再试试另一颗粉钻
I think that’s really interesting the pink diamond fluoresce is blue,
我觉得粉钻发蓝色荧光很有趣
but you wouldn’t have guessed that.
你肯定猜不到
I’m in the sorting department
现在我所在的地方是筛分部门
where the raw diamonds are graded.
原石在这里进行分级
It’s really amazing.
这里很神奇
The diamonds that come here look rather like sand
送到这里的钻石看起来像砂子一样
if you look here in this bowl
看看这个碗里
I can just pour some out,
我可以这么倒着玩
but what’s amazing is
但最令人惊讶的就是
that people go through this literally grain by grain.
这里的人真的是一颗一颗过目的
They have about 8,000 different grades.
这里给钻石分成8000个不同等级
Which they know. They remember
工作人员背下分级标准
and they classify each of the grains according to the grade
然后按照标准给每一颗钻石分出等级
and here we have about 26 or 27 thousand karats in weight of diamonds
这里大约有26000或27000克拉钻石
the total value of this doesn’t look very much
看起来不多
is more than a million dollars.
但它们的价值超过100万美元
That’s why people are watching me carefully
所以这里的工作人员很认真地监督我
I’m wearing a special coat. No pockets!
我穿的制服也是特制的 没有口袋噢!
And even these tiny grains look like little octahedra, tiny crystals.
即使是看上去这么小的晶体 也是八面体
And you’ve got to remember that
你需要知道的是
these grains have been obtained from a solid mass of rock
这些钻石是从大块矿石中开采出来的
Which has been ground up and out of the rock.
他们开采出矿石 把矿石打碎
They filter off these special diamonds.
然后挑出里面这些特别的钻石
And what’s interesting here is that you can see different colors
有趣的是 这些钻石的颜色是不同的
some of the grains look a bit yellow
有些是黄色的
some look really clear
有些很透明
one or two are grey
还有一两颗是灰色的
so It’s like my hair
就像我的头发一样
but my hair should be graded in color.
我的每根头发灰度也是不一样的
Particularly interesting for me
最令我感到有趣的是
is that all of this is sorted by hand.
这些钻石都是人工筛选的
Because they are so valuable
因为它们价值太高了
that it’s worth people looking at each one individually.
值得一颗一颗过目
That’s why every diamonds should be to you really special.
所以 每颗钻石对你来说都是特殊的
It’s amazing,
好神奇
I’ve never seen anything like this
我从没见过这样的场景
it’s (it’s) unbelievable.
真是不可思议
They’re going to let me touch it with my hands
工作人员允许我上手摸一摸
watch carefully
仔细看哦
only time in my life
我这辈子唯一一次机会
I’m going to wash my hands in diamonds.
我要用钻石洗手啦!
Feels just like sand
摸起来手感像沙子
it’s quite strange
这挺奇怪的
it feels a bit like metal.
感觉有点像金属
Because diamonds conducts heat very well.
因为钻石导热性非常好
So it feels as if I’m holding metal.
所以感觉起来就像拿着金属
I think I could do this for quite a long time if they let me.
如何他们允许的话 我可以玩上很久
But still
不管怎么说
Here you’ve got a million dollars worth of diamonds.
摆在这里的是价值一百万美元的钻石
Literally running through my fingers.
流过我指尖的钻石啊
Some of them are sticking to my hand. Prof:
有些还粘在我手上了
get them off
赶紧弄下来
手上啥也没有 在她那呢
Brady: Got anything on there?
你有藏东西吗?
Prof: They are clean
没藏 手上可干净了!
I think this is the most extraordinary thing I’ve ever done on Periodic Videos
我觉得这是《元素周期表》频道最特别的一期了
and certainly the most fun.
当然也是最好玩的一期
The gold is an exciting element
金是最激动人心的元素
It has interesting chemistry
它的化学性质很有趣
and it’s just sitting here doing nothing.
可它们就摆在这 派不上任何用场
Its enormously impressive.
令人非常印象深刻
But it’s a bit sad
但也有点伤感
rather like a mausoleum.
这里就像陵墓一样
