Slight shades of red make all the difference in a ruby’s value. The most valuable of rubies has a vibrant, uniform red color with a slight hint of purple. If the color is too orange or purple, the ruby’s value dips slightly. It is also important that the ruby is not too light or dark either. A ruby that is too light is actually pinker than desired.

Since inclusions are basically cracks inside the ruby’s interior, the ruby is more brittle or fragile, with inclusions beneath the surface being the most detrimental to its wholeness.

Not all inclusions can make a ruby look worse, however. Some inclusions can cause light to spread across a facet that may look spectacular to the public eye. This makes the color across its crown to be more saturated and vivid.
