What Other Types of Diamonds Are There?

The ideal diamond is completely colorless. You can have some diamonds which are completely colorless. Other diamonds can have some slight coloring or completely colored.

VVS1 – VVS2

VVS diamonds are very very slightly included. Even with a 10 x magnification, only an expert can detect any flaws. A normal person wouldn’t be able to notice these flaws.

The difference is that a VVS1 has flaws at the bottom. A VVS2 has flaws at the top of the diamond.

VSI – VS2

You cannot see flaws with the naked eye in VS diamonds. When using a 10x microscope, seeing the flaws is not easy. But you can see them, if you were to look closely for a few seconds.

SI1 – SI2

SI diamonds have flaws. They are easily visible to see using a 10x microscope. They cannot be seen without a microscope.

I1 – I3

For I diamonds, flaws are quite visible. They can be easily seen by the naked eye. These are the less expensive types of diamonds.

Are FL and IF Diamonds Worth Buying?

My honest answer is, no. Unless you have more money than you know what to do with. They are not worth buying. Save yourself some money. Put it towards something else like a vacation.

You could always buy a less expensive diamond. Like a VVS. Since you can’t see the flaws without a magnification anyway. To the bare eye, they’ll look no different. I promise, no one is going to question you about your diamond.

An IF or FL diamond will not look any different than a VS2 or even an SI1 diamond. Why? Because you cannot notice the flaws without a microscope. So if you want to save your money, buy a lower grade diamond.

If you want to spend your money on an expensive diamond, go for it. That is your choice, not anyone else’s.
