This month I want to talk about yellow Citrine. It is November’s birthstone and also the gem of 13th anniversary. The followings are some facts about Citrine I think that are good to know.
1. Citrine is Amethyst.
The first time I came across this gemstone was when I did my internship in 2007 in a jewelry manufacture in Hong Kong. In the company’s showroom, they put Amethyst Geodes and Citrine Geodes next to each other. I asked my boss if they were the same type of gemstones since they looked identical. The only differences were their colors. Citrine is yellow while Amethyst is purple. My boss told me they were the same type of gemstone. I was really confused by his answer. Later I learned that Citrine is Amethyst. When Amethyst is heated, it turns yellow.
2. Natural Citrine is rare.
Natural Citrine is very rare and most Citrine in the market is heat treated Amethyst. The price is fairly reasonable.
3. Citrine is a type of Quartz.
This is where it gets confusing sometimes. So Citrine is a type of Quartz like Ruby is a type of corundum. Amethyst, Citrine, Rose Quartz, Smoky Quartz, Rock Crystal, and Aventurine are all Quartz.
4. Hardness 7
Citrine’s hardness is around 7. It is harder than Turquoise and softer than Topaz. Sometimes people use it as the medium for scratch test.
Okay, that’s all I know about yellow Citrine. I need to nap again as I am still struggling with jet lag. I want to post an article about my trip in October. I couldn’t post anything during my trip due to slow internet. Stay tuned.
