Good Ruby Cut and Shape

Ruby is often mixed-cut, with brilliant-cut crowns and step-cut pavilions. The most common shapes are ovals and cushions. Other cuts are also available, such as round, triangular, emerald-cut, pear and marquise cuts. However, these shapes are difficult to find in larger sizes, since they do not preserve the rough weight as well as ovals and cushions.

Good Ruby Color

The color of ruby is its most important quality factor. The most sought after color is a strong pure red to red with a hint of blue. This vibrant red hue is known as 'pigeon's blood'. When the color of ruby is too light, it is classified as pink sapphire, but the line between pinkish-red ruby and pink sapphire varies by region.

Good Ruby Clarity and Luster

Ruby typically displays inclusions and these are tolerated as part of the nature of the stone. However, when inclusions minimize transparency or brilliance, they decrease the value. Ruby that is free from eye visible inclusions is available, however, large eye clean gemstones are rare and extremely valuable.

Good Ruby Treatment

Ruby is exposed to heat treatment in order to enhance the color. This is considered to be a stable and permanent enhancement. Intact rutile inclusions (also known as 'silk') provide proof that a ruby gemstone has not been heat treated. Ruby is also irradiated and treated with diffusion to enhance the color.
