How Color Determines the Value of a Ruby?

Colour is the most important and significant factor that determines the grade of the rubies.  Ruby stone are found in red colour which is because of the presence of chromium in the stone. From light red to pale and dark red, the gem is found in different tones and saturation levels.

Let's discuss how the color distinguishes the quality of the stone: 

High - Quality Ruby stones have vivid red colours, they are mostly bright red and have excellent saturation. These gems have a medium dark tone, and mostly the colour is evenly distributed throughout the stone. Sometimes, it have a shade of purple in it as well.

Medium-quality fems have less vivid colour their tone is either medium dark or light, and have a secondary hue, so they are like pinkish red, purplish red, blackish red, and orangish red.

How Clarity Affects Ruby’s Quality?

Clarity is the absence of inclusions in a gemstone; the fewer the flaws, the more the clarity. Inclusions are very common in gemstones; they naturally occur and so are acceptable. Some gems have more inclusions than other. 

High-quality rubies are considered to the the ones that have more clarity that is up to no visible imperfections. They are ‘eye clean’, which means even if there are any inclusions in the gem, they are not visible to the naked eye. 

Medium-quality gems will have fewer inclusions and at places where they are not directly visible to the naked eye. 

Low quality are those that have a higher number of inclusions, meaning have less clarity. Clarity affects the transparency and the overall appearance of the gemstone, and hence their value is very low.

Importance of Cut 

The cut of a gemstone will also affect its quality because it affects the brilliance, colour and overall appearance of the ruby. 

A well-cut ruby with precision maximises the look of the stone, it enhances the natural beauty of the gem and showcases the colour and clarity better. Such rubies are considered to be of a high standard. Gems of accurate cut have symmetrical facets and proportions. 

Medium-quality ruby stones have minor imperfections in the cut. They might have uneven facets, or inclusions are visible in the facet, or there can be slightly off proportions. They will still be attractive, although they might not exhibit the same brilliance as the high-quality Manik stone

The low-standard rubies will have a poor cut. They will have very unsymmetrical facets, and the proportions will not be good as well. This will lessen their beauty and increase the risk of scratching the stone.

Treatments & Enhancements 

The treatments done on the gemstones can also affect the ruby stone price and appearance as well as standards. 

High-quality Manik stones are those that are not treated at all or have minimal treatments or enhancements done on them. 

Medium standard gems often undergo common treatments for the betterment of their overall appearance, like heat treatment. 

Low-grade gemstones are heavily treated as they are pale or very dull in colour. The treatments make them look like they are of very good quality. Mostly, these gems are glass-filled, which makes the gem look very promising. However, these enhancements compromise the value as well as the durability of the gemstone.
