Some people even state that this is the most colorless a diamond could ever be.

However, note that these colors are not visible to the naked eye. Luckily there are microscopes to help differentiate between the two color grades. In a case like this, the price difference is also significant. As a general opinion, the best recommended Oval cut Diamond color is the H color.

When buying that diamond you have set your eyes on, remember that a stone with the most carats does not necessarily mean that it is the best diamond in the market. Here is another secret.
