What Is A Cabochon And Why Are Opals Cut Like ThisWhen you look at a gemstone, you might not immediately know that the cut significantly shapes its sparkle, luster, and brilliance. For example, a round brilliant cut diamond yields the most sparkle possible thanks to strategically placed cuts. However, there is a class of gemstones that aren’t cut but polished. That’s because some gems aren’t translucent, but opaque. The technique is called cabochon, and it’s seen on smooth gems like opal, garnet, jade, jasper, and even some emeralds. So, what is cabochon, and why are opals cut like this?

Not only does polishing and smoothing opals showcase their spectacular rainbow of colors, but it protects the gem from chipping or breaking. And that’s not the only benefit of cabochon cutting.

Keep reading to learn all about the history, meaning, and advantages of cabochon opals!

What Is A Cabochon Gem?

Most gemstones are faceted to let the most amount of light pass through the stone. However, the benefit of faceting best suits translucent gems like diamonds or sapphires. What about opaque gemstones that have a visible body tone, like opals?

A cabochon gem is a stone that’s shaped with polishing instead of faceting. Mostly, these gems are round or oval, and have convex faces and a dome-shaped base. The fantastic feature of a cabochon is that it’s shaped without actually cutting facets into the gemstone.

The most popular cabochon shape is oval, which leads us straight into opals! You might gather that opals are the most popular cabochon gemstone. But why are opals cut cabochon?

We’ll get to that, but first, let’s talk a little more about the meaning of opal cabochon.

Opal Cabochon Meaning

Most opals are cut in an oval cabochon, but what is the meaning of cabochon? If you have an affinity for language, you might guess that the word cabochon has French origins, and you’d be correct! In French, the word caboche means a small dome or knob. Many experts in the jewelry and gemstone world refer to cabochon as a cab, a short-and-sweet nickname.

Of course, opal has its own meaning and origins, too, but the history is much older. Opal comes from upala, the Sanskrit word for precious stone. Some years later the Greeks adopted the name Opallios, which translates to seeing a change of color. Of course, this meaning depicts the natural phenomenon known as play of color, the effect of fiery flashes of color dancing across the surface of an opal cabochon.

Put the two together, and opal cabochon meaning is more or less, “to see a change of color on a small dome or knob.”

Perhaps that’s too direct a translation, but you get the idea: opal cabochons are small, oval gemstones that feature bright, changing colors. Any guesses as to why the cabochon cut best suits the opal?

If color is on your mind, you’re on the right track!

Why Are Opals Cut Cabochon?

For us to best explain why opals are cut cabochon, we have to take a brief walk through gem-cutting history.

European Advances in Gem Cutting

Today, most gemstones are cut and faceted to illuminate the color, sparkle, and brilliance of translucent stones. However, for centuries, the only style of gemstone cutting was cabochon. That’s because gemstone faceting wasn’t developed until 14th century Europeans turned it into an art form thanks to the invention of the cutting-wheel.

What followed was intricately cut geometric shapes and facets to best let light pass through and exit the stone. The more light, the more sparkle.

The Renaissance Kickstarted Faceting

During the commencement of the Renaissance, the artistic rebirth that swept through Europe, avant-garde artists pushed the envelope on classic trends and styles. At the centerfold? The prevalence of light.

Despite these discoveries and progressions of gem cutting, there still remained benefits to the traditional cabochon style. Namely, there are certain gems that best exhibit unique properties from polishing, rather than cutting.

Cabochon Is Having Its Own Renaissance

Since the invention of gemstone faceting, the cabochon style has mostly faded out of popularity with the exception of a select group of gems. However, in recent years, the cabochon style is having somewhat of its own renaissance.

The resurgence in popularity is primarily because trends are favoring more natural, minimal stylings. For example, rose quartz cabochon rings and pendants have swept through the jewelry industry. Opal itself is enjoying a well-deserved moment in the spotlight. As an ethically sourced gemstone, opals are moonlighting on the red carpet as the choice accessory among celebrities and style icons.

Plus, there are quite a few advantages of cabochon gemstones!
What Is A Cabochon

Benefits of the Cabochon Style

  • Some gems like rubies and garnet exhibit asterism, a star-like pattern on the stone best seen from cabochon polishing.

  • Opals have an opaque body tone and cutting them cabochon best displays play of color.

  • Cabochon opals don’t have corners or edges, so they are more resistant to chipping and breaking.

  • If a cabochon opal is damaged, it’s easy to re-polish its surface to smooth out the flaw.

  • Cabochon polishing with a high dome yields more play of color across the stone.

  • Opals are a softer gemstone, ranking at 6 for hardness, meaning they are more susceptible to scratches and damage. However, the scratching is less visible on a smooth, cabochon stone than a faceted one.

什么是凸圆形,为什么要像这样切割蛋白石当您查看宝石时,您可能不会立即知道切工会显着影响其闪光,光泽和光彩。例如,由于有策略地放置切工,圆形明亮式切工钻石可产生最大的光彩。但是,有一类不是切割而是抛光的宝石。那是因为有些宝石不是半透明的,而是不透明的。该技术被称为凸圆形宝石,可以在蛋白石,石榴石,玉,碧玉,甚至一些祖母绿等光滑宝石上看到。那么,什么是凸圆形宝石,为什么要像这样切割蛋白石呢?

抛光和平滑蛋白石不仅展示出其壮观的色彩彩虹,而且还可以保护宝石免于碎裂或破裂。这不是凸面切割的唯一好处。

继续阅读以了解所有关于凸圆形蛋白石的历史,含义和优势!

什么是凸圆形宝石?

大多数宝石都有刻面,可让最多的光穿过宝石。但是,最佳刻面的好处是适合半透明的宝石,例如钻石或蓝宝石。像蛋白石一样具有不透明的,具有明显肤色的宝石呢?

凸圆形宝石是经过抛光而不是刻面成形的石头。通常,这些宝石是圆形或椭圆形的,并具有凸面和圆顶形的基底。凸圆形宝石的奇妙特征在于,它的形状没有将切面切成宝石。

最受欢迎的凸圆形形状是椭圆形,这使我们直接进入蛋白石!您可能会发现蛋白石是最流行的凸圆形宝石。但是为什么蛋白石切成凸圆形呢?

我们将解决这个问题,但是首先,让我们进一步讨论蛋白石凸圆形的含义。

蛋白石凸圆形的含义

大多数蛋白石是切成椭圆形的凸圆形切割的,但是凸圆形切割的含义是什么?如果您对语言有亲和力,则可能会猜出凸圆形这个词源于法国,这是对的!在法语中,caboche一词的意思是一个小的圆顶或旋钮。珠宝和宝石界的许多专家都将凸圆形宝石称为“出租车”,这是一个简短而甜美的绰号。

当然,蛋白石也有其自身的含义和起源,但是历史要悠久得多。蛋白石来自upala,梵语是宝石的意思。几年后,希腊人采用了名称Opallios,意思是看到颜色的变化。当然,这种含义描述了一种自然现象,即所谓的色彩发挥即在蛋白石凸圆形表面上舞动的彩色火光的效果。

将两者放在一起,蛋白石凸圆形的含义或多或少是“在小圆顶或旋钮上看到颜色的变化”。

也许那是太直接的翻译,但您会明白:蛋白石凸圆形宝石是小的椭圆形宝石,具有明亮多变的颜色。关于凸圆形切割为什么最适合蛋白石的任何猜测吗?

如果您在想颜色,那您就走对了!

为什么蛋白石切成凸圆形?

为了让我们最好地解释为什么将蛋白石切成凸圆形,我们必须简短地了解宝石切割的历史。

欧洲宝石切割技术的进步

如今,大多数宝石都经过切割和刻面处理,以照亮半透明宝石的颜色,闪光和光泽。但是,几个世纪以来,宝石切割的唯一风格是凸圆形。这是因为直到14世纪,由于切割轮的发明,欧洲人才将宝石刻面转变为一种艺术形式。

接下来是复杂地切割几何形状和刻面,以使光线最好地通过并离开石材。光线越多,就越闪耀。

文艺复兴时期开始刻面

在文艺复兴时期,席卷整个欧洲的艺术复兴,前卫艺术家推动了经典趋势和风格的发展。在对折?光的盛行。

尽管有这些发现和宝石切割的进展,但传统的凸圆形风格仍然有好处。即,某些宝石最能表现出抛光而不是切割的独特特性。

凸圆形的复兴

自从宝石刻面的发明以来,凸圆形的风格已逐渐淡出人们的视野,除了精选的一组宝石外。但是,近年来,凸圆形的风格有所复兴。

受欢迎程度的回升主要是因为趋势倾向于更自然,更简洁的样式。例如,玫瑰石英凸圆形戒指和吊坠席卷了珠宝行业。蛋白石本身在聚光灯下享受着当之无愧的时刻。作为符合道德标准的宝石,蛋白石在红地毯上显得月光明媚,是名人和时尚偶像中的首选配饰。

另外,凸圆形宝石还有很多优点!

  • 蛋白石具有不透明的身体色调,可以将它们切割成凸圆形,以最好地显示色彩。

  • 凸圆形蛋白石没有角或边缘,因此它们更耐碎裂和破碎。

  • 高圆顶的凸圆形抛光可在整个石材上产生更多色彩。

  • 蛋白石是一种较软的宝石,硬度排名为6,这意味着它们更容易受到刮擦和损坏。但是,在光滑,凸圆形的石头上,比刻面的石头更不容易看到划痕。
