HCA score question

[NatalieE]

On the hca page it says that 0-1 scores are not the best suited for rings, any idea why this would be. I am looking at a 0,9 hca diamond for a ring.

Thanks in advance

Can I piggyback and ask what an HCA 0.00 would look like?

Because they tend to be shallower, and shallower stones tend to obstruct more (sometimes too much) when you lean over them.

A person who has light hair and skin may see less over-obstruction (ie. Shallower stones are more forgiving) than a person with a darker complexion. A person with large, bouffant hair will see more obstruction at a given angle and distance from the stone than someone with a petite head and hair pulled back.

Did you know that "fire" and "scintillation" are not the same thing? "Contrast" and "leakage" also differ from each other.

There are competing factors. The most brightness does not occur with the most fire. The most fire has a smaller spread
