Usually, if you want to become a pro in the gemstones you have to make a long way of study and practice. To understand the gemstones, you start study a lot of things, that might seem you quite boring: the crystallization systems, MOH, refractive index, birefringence, crystal axes, special gravity, chemical, physical properties, hue, saturation etc... When you open gemstones’ guide, I believe that last thing you want to see are the terms and definitions that are needed to be explained and studied. I promised to you to make it easier for you to understand, so I will keep my word.

Let’s say you want to buy the ruby for your ring, the first thing you do is to google it, or to look for a ruby at eBay or at Amazon. Now, what do you see? A lot of rubies starting from few dollars and up to hundreds of thousands $ per carat. I believe your next thought is what the… is going on here??? I know that ruby is a precious stone. How could it cost less than lunch at McDonalds?

$ 3,99
$ 5,00
$ 1,89

Ok. Let’s start. How can we determine that the precious stone like ruby, emerald or sapphire is cheap or expensive? There are 3 things we are looking for:

1.The size. To be more correct, the weight in carats. The bigger is the weight, the higher is the price per carat.

$ 800
$ 3000
$ 10000
$ 26000

2.The transparence. The clarity. The more transparent is the gemstone, the higher is the price.

$ 70
$ 550
$ 3000
$ 8000

3.The color. The richer the color, the higher is the price.

$ 150
$ 1000
$ 6000
$ 22000
