How To Know A Good Ruby

Rubies are among the most sought-after gemstones in the world, and for good reason. Their captivating red color and lustrous appearance make them a favorite among collectors and jewelry enthusiasts alike. If you’re looking to purchase a ruby, it’s important to know how to identify a good one. In this blog post, we’ll discuss what factors to consider when evaluating a ruby’s quality and provide tips on how to choose the best one for you.


The most important factor when it comes to evaluating a ruby’s quality is its color. Rubies are famous for their intense red hue, and the best specimens display a vivid and saturated color. The most desirable shade of red is often referred to as pigeon’s blood, which is a deep, pure red with a hint of blue.

To determine the color quality of a ruby, examine the stone under different lighting conditions. Does the color remain consistently vivid and bright? If so, that’s a sign of a high-quality ruby. A strong, even color is more valuable than a stone with color inconsistencies or patches.


Like other gemstones, the clarity of a ruby refers to the presence of inclusions, or imperfections, within the stone. While it’s rare to find a completely flawless ruby, a high-quality stone should have minimal inclusions that do not affect its overall appearance or durability. Inclusions that are easily visible to the naked eye can detract from the ruby’s beauty and value.


A well-cut ruby will display its color and brilliance to the best advantage. The cut should also minimize the appearance of any inclusions while maximizing the stone’s carat weight. The most common cut for a ruby is the oval shape, but other popular cuts include cushion, round, and emerald. When evaluating a ruby’s cut, pay attention to its proportions, symmetry, and overall finish.

Carat Weight

Carat weight is another important factor to consider when evaluating a ruby’s quality. Larger rubies are rarer and thus more valuable, but bear in mind that a high carat weight alone does not guarantee a good ruby. It’s essential to consider color, clarity, and cut in conjunction with carat weight to determine the true value of a stone.


When searching for the perfect ruby, keep in mind the four Cs: color, clarity, cut, and carat weight. A good ruby will have a vivid, saturated color, minimal inclusions, a well-proportioned cut, and a desirable carat weight. By paying attention to these factors, you’ll be well on your way to finding a beautiful, high-quality ruby that you’ll treasure for years to come.
