钻石的英文简写是DO,全称diamond。
钻石因为具有极高的反射率,其反射临界角较小,全反射的范围宽,光容易发生全反射,反射光量大,从而产生很高的亮度。
钻石的闪烁就是闪光,即当金刚石或者光源、 观察者相对移动时其表面对于白光的反射和闪光。无色透明、结晶良好的八面体或者曲面体聚形钻石,即使不加切磨也可展露良好的闪烁光。
扩展资料钻石(金刚石)还具有非磁性、不良导电性、亲油疏水性和摩擦生电性等。唯Ⅱb型金刚石具良好的半导体性能。根据金刚石的氮杂质含量和热、电、光学性质的差异,可将金刚石分为Ⅰ型和Ⅱ型两类,并进一步细分为Ⅰa、Ⅰb、Ⅱa、Ⅱb四个亚类。
Ⅰ型金刚石,特别是Ⅰa亚型,为常见的普通金刚石,约占天然金刚石总量的98%。Ⅰ型金刚石均含有一定数量的氮,具有较好的导热性、不良导电性和较好的晶形。
Ⅱ型金刚石极为罕见,含极少或几乎不含氮,具有良好的导热性和曲面晶体的特点。Ⅱb亚型金刚石具半导电性。由于Ⅱ型金刚石的性能优异,因此多用于空间技术和尖端工业。
世界上最大的工业用金刚石和宝石级金刚石都超过3100克拉(1克拉=200毫克)。其中宝石级金刚石的尺寸为10×65×5厘米,名叫“库利南”,1905年发现于南非的普雷米尔岩管。
中国常林钻石,重158786克拉,于1977年被山东临沭县常林大队女社员魏振芳发现,后列为世界名钻。世界金刚石主要产地有南非、澳大利亚、扎伊尔、博茨瓦纳、俄罗斯。

"唉!我可怜的玛蒂尔德!可是我那一挂是假的,至多值五百法郎!……"(以下开始):
可怜的玛蒂尔德一听到这句话立即昏天旋地起来,天像是要塌下来一样。她抓住佛来思节夫人:"我的天哪,那项链,我的青春哪,赔我,赔我……"话未说完便昏了过去,不省人事。
冥冥中她又觉得自己回到了那个宴会,戴着真正的钻石项链,疯狂地旋转着。这时,一为女宾走来,"她一定是忌妒我的美貌,"她想。这个女宾走上前,说:"夫人觉得好些了么?"这时玛蒂尔德才知道自己身在医院的病床上。
十年的青春,千年的美貌,竟然葬送在一条项链上!?马蒂尔德真希望这是一场梦。
佛来思节夫人来看她了。她们达成了协议,马蒂尔德可以选择接受四万法郎,或者那条项链。另外,佛来思节夫人还会付给马蒂尔德六千法郎精神损失费。
她接受了后者。
她戴着项链回家去。路上她心想:"我总算拥有一条自己的项链了。"但是,当她丈夫知道她选择的不是钱,便破口大骂:"你这笨蛋!难道钻石项链能使你填饱肚子?你戴着它活一辈子吧!"说罢,带着六千法郎,摔门而去。
马蒂尔德彻底绝望了。但是,她宁可沿街乞讨也不愿卖掉项链,更不愿不择手段地生活下去,这是她一生的信念,她自信这一生并不欠别人什么。
圣诞节来临了,圣洁的雪花从天上飘落下来,大的有梅花那么大,满天飞舞,夹着烟霭和忙碌的气色,用厚厚的雪褥覆盖了整个巴黎城。人们有的唱歌跳舞,有的互赠礼物,在着欢乐的气氛中,全然没有人注意墙角坐着一位破衣烂衫的乞丐,颈上挂一条钻石项链。

首饰(jewelry/jewellery)是一种个人装饰品(an item of personal adornment)。
如项链(necklace)、戒指(ring)、手镯(bracelet)。它通常用宝石(gemstone)或贵金属(precious metal)制作,但也可以是其它材料(material)的。
首饰本来的功能是储存财富(wealth storage)或将衣物(clothes)或头发(hair)固定。但很早就开始变成了个人装饰物。
首饰的作用主要包括货币(currency)、财富展示(wealth display)、实际功用(functional use)、象征(symbolism)、保护(protection)、艺术展示(artistic display)等。
除了常见的首饰之外,还出现了艺术首饰(art jewellery)与便宜的时装首饰(costume jewellery)。
高级首饰(fine jewellery)通常用黄金(gold)、白金(white gold)、黄金与白色金属的合金(alloy)、铂金(platinum)、钯金(palladium)、钛金(titanium)与白银(silver)制作。
黄金纯度(purity)用K(karat)标记。

时装首饰也用不锈钢(stainless steel)。
制作首饰的宝石包括钻石(diamond)、琥珀(amber)、紫水晶(amethyst)、祖母绿(emerald)、玉石(jade)、碧玉(jasper)、石英(quartz)、黄水晶(citrine)、红宝石(ruby)、蓝宝石(sapphire)、绿松石(turquoise)等。
