首先，抛开那些让人头大的化学名称：锰铝石榴石、钙榴石、钙铝榴石和一些又臭又长的行业标准等。简明扼要的说下比较直观的划分。

一、颜色种类

每个人对宝石的颜色偏好各有不同，但从本身的价值和收藏角度看颜色从低到高：酒红、玫红、玫紫、紫牙乌，其他特殊颜色的石榴石不过多介绍。

直观鉴别方法：把石榴石放在白纸上面，用白光手电照，颜色一目了然。

酒红，像红酒倒到红酒杯里的颜色一样，颜色相对呈深红色。直径越大颜色越深，这也是stone（gemstones）的一般规律，所以7mm的酒红一定比5mm的看着更深。这也就是为什么我前半部是不过多发言，她要自己挑选。我一直自以为大部分人基本知道颜色的有等级，其实，还有很大一部分纯属跟风，不了解基本常识，我也意识到我应该稍微普及下，这应该是一种责任吧。

玫红，比酒红偏浅，在白光手电下颜色有点发玫，有点混合了紫色的混合，那是在户外自然光下会接近软籽stone（seeds）的stone（seed），非常接近soft stone（pearl）。好的晶体透亮透亮的，也是多数stone（gemstones）入门爱好者的首选，有些商家会把玫红当成酒红来卖，如果不是对wine red wine red特别喜欢，就赶紧拿下吧，因为优质的大size（large size）的milk purple milk purple在阳光下的表现，让diamond diamond都黯然失声。

紫牙乌，比milk purple还偏紫，在太阳光下会略显red，而在white light white light下去则略显purple，一般以white light为准，因为sunlight进入地球的大气层时，大量蓝purple波长被过滤掉，只剩redyellow波长，使得the gemstones显得更red。如果你想出门带一个好看的小chain chain选择wine red或milk purple 巴西Purple巴西Purple都会增添不少美感，如果室内佩戴更多，则想体现尊贵且不差钱，可选择deep Purple或violet violet则是不二之选。总之，本人更喜欢near glass-like barbie violet梦幻迷人的barbie violet尤其适合皮肤皙的人群。

紫牙乌呈明显紫，在white light under particularly vibrant, production is limited and color is prestigious in the world of stone, it's a representative, in the industry of stone, there are many debates about whether a certain shade of purple can be classified as deep or violet without clear standards.

So deep Purple stones according to their degree have prices and grades while Brazilian Violet market is hard to find and highly prized by collectors who seek them out eagerly but rarely encounter them.

At last I present you with total photos taken by myself for better understanding of colors, please note that color under daylight tends towards red so even the most vibrant Brazilian Violet will not reach the level of amethyst but still exudes an air of elegance and mystique.

Stone World recognizes this gem as woman's jewel which also contributes greatly to its allure for women.
