6提示选择彩色钻石





彩色钻石,或花哨,是国际拍卖一块去抵抗,达到非常高的估计,往往超过他们。当然,这些是对色相,纯度和重量显着的材料,但所有的彩色钻石是相当独特的,即使当涉及到一克拉结石:内部的杂质,该方法的组合物中,着色的方式不同石(对于绿色因辐射,蓝色是由硼,黄,橙从中吸收蓝色光)的氮分子给出。认证是一个有价值的工具,因为它列出了所有这些标准,4个C,它决定了价值。一种基本的拼音,而我们已经说过(http://gioiellis.com/tutto-sui-diamanti/),在彩色宝石的情况下,有其他因素产生不同的含义。我们必须考虑到,钻石可能有更多的颜色放在一起:一些宝石是纯洁的,别人有辅助颜色,这给他们带来了阴影。看上黄绿色的钻石将是一个黄色的石头有绿色的色调,而淡黄绿色的钻石都会有一个轻微的黄色色调。可能会造成混淆,但二级颜色来自主之前。

1第一个因素R.稀有度:只有1个在10 000是彩色宝石。对他们来说,花哨的钻石被分为三组:棕色,灰色和黄色是比较多见的。第二组包括那些具有更鲜明的黄色和橙色色调。在第三,却是那些具有作为其主要颜色为橙色,绿色,紫色,粉色和蓝色:他们是极其罕见的。所以,虽然次要色降低它的价值,一个纯粹的棕色钻石总会比一个浅棕色基调的粉色钻石便宜。最后,还有红色的(http://gioiellis.com/se-diamante-rossocome-rose),而是一个单独的类别,甚至许多珠宝商都从来没有见过。

2第五℃。荧光,即紫外线辐射的石材的显色反应,通常被认为是一个缺陷,并因此影响了价格。有,但是,异常:对从H了无色荧光石头变成一个优势,因为使石头更白(白色的规模从D到Z,几乎黄色云)。在彩色的是不相干的东西从黄钻,它必须是零或轻微的一部分。

3克拉重量的步骤。在一般情况下,一个金刚石1克拉的价格比为同一类别的0.90克拉石通过的值高25%。与质量的增加的差增大,甚至达到70%时带有一个D无瑕石。在彩色宝石它变得更加复杂:例如,从0.50克拉激烈的粉色钻石可以花费比从零点20克拉相当于六倍多,因为每克拉它的价格要高得多,克拉重量高于同2.5倍。而在较低的颜色,如浅黄色的范围内,该差异不超过30%。因此,一切都取决于颜色的强度。

4夹杂物。不鼓励石头的选择,尽管有一个美丽的色彩的词。据专家介绍,最好的价值是明晰VS2的分类。但是这也适用于无色结石。相反,在彩色钻石SI1和SI2的情况下,该内含物通常是不可见的肉眼。那么,为什么支付更多的时候整体美观效果不被损害?

5剪切。在标本无色供应,以实现最大的辉煌。相反,钻石的情况下,花式切割供应以获得最大的颜色,高举。举个例子:公主和圆形切割的,因为它们反射光线的方式,减轻了颜色,而软垫或椭圆形切割提高了音调。这就是为什么,第一成本比后者多,因为他们是罕见的。然后最追捧。

6设置。即使一个不太鲜艳的颜色可以与集增强。例如,为浅黄色钻石与金黄色的GRIFFES,将变得更




3 Carat weight steps. In general, the price of a diamond 1 carat is 25% higher than the value adopted for a stone of 0.90 carats of the same category. The difference increases with the increase of the quality and even reaches 70% with a D Flawless stone. In colored gemstones it gets further complicated: for example, an intense pink diamond from 0.50 carat can cost six times more than an equivalent from 0:20 carat, because its price per carat is much higher and the carat weight is the same 2.5 times higher. While in the range of lower color, such as pale yellow, the difference does not exceed 30%. So, everything depends on the intensity of the color.

4 Inclusions. A word that discourages the choice of a stone, despite having a beautiful color. According to experts, the best value is in the classification of clarity VS2. But this applies to colorless stones. Instead, in the case of colored diamonds SI1 and SI2, the inclusions are often invisible to the naked eye. Then, why pay more when the overall aesthetic effect is not compromised?

5 Cut. In specimens colorless serves to achieve maximum brilliance. Instead, in the case of diamonds fancy cut serves to get the most of the color, to exalt. An example: princess and round cut, because of the way they reflect light, attenuate the color, while the cushion or oval cut enhances the tonality. That’ why, the first cost much more than the latter, because they are rarer. And then the most sought after.

6 Setting. Even a less vibrant color can enhance with the set. For example, a pale yellow diamond with the griffes in yellow gold, will become more intense. The same applies to the brown and pink diamonds with the rose gold.
