How To Tell If A Ruby Is Good Quality

Rubies are precious gemstones known for their vibrant red color, durability, and rarity. They are a symbol of love, passion, and power, making them a popular choice for engagement rings and other fine jewelry. But, how can you tell if a ruby is of good quality? In this blog post, we will discuss the factors to consider when evaluating the quality of a ruby.

1. Color

The most important factor in determining the quality of a ruby is its color. The finest rubies have a pure, vibrant red hue with a slightly bluish undertone. This color is often referred to as “pigeon’s blood red.” Rubies with a strong or intense red hue are considered more valuable than those with lighter or darker shades.

When assessing the color of a ruby, consider the following three aspects:

  • Hue: The basic color of the ruby. The hue should be as close to pure red as possible, without any brown or gray overtones.
  • Tone: The lightness or darkness of the color. A high-quality ruby should have a medium to medium-dark tone.
  • Saturation: The intensity or vividness of the color. A top-quality ruby should have a strong saturation.

2. Clarity

Clarity refers to the presence of inclusions or blemishes within the ruby. While it’s rare to find a completely flawless ruby, a high-quality gemstone should have minimal inclusions that are not visible to the naked eye. Inclusions can affect the durability and overall beauty of the ruby, so it’s important to choose a stone with good clarity.

When evaluating the clarity of a ruby, use a 10x jeweler’s loupe to examine the gemstone closely. Look for any visible inclusions or blemishes and consider their size, number, and location. The fewer the inclusions, the better the clarity and overall quality of the ruby.

3. Cut

The cut of a ruby can greatly impact its beauty and value. A well-cut ruby will display excellent symmetry, proportion, and polish, which enhances its color and brilliance. On the other hand, a poorly cut ruby may appear dull or lifeless, even if it has a good color and clarity.

Some popular ruby cuts include the oval, round, cushion, and emerald cuts. When evaluating the cut of a ruby, pay attention to the following factors:

  • Symmetry: The facets of the ruby should be symmetrical and evenly aligned.
  • Proportion: The size and shape of the facets should be well-balanced and in proportion to one another.
  • Polish: The surface of the ruby should be smooth and free from any visible polishing marks or scratches.

4. Carat Weight

Carat weight refers to the size of the ruby, with one carat equaling 200 milligrams. As with most gemstones, larger rubies are generally more valuable than smaller ones. However, it’s important to remember that a larger ruby with poor color, clarity, or cut may be worth less than a smaller ruby with exceptional quality.

When evaluating the carat weight of a ruby, consider not only the size of the gemstone but also its overall quality. A well-balanced combination of color, clarity, cut, and carat weight will result in a high-quality, valuable ruby.

Final Thoughts

Evaluating the quality of a ruby may seem challenging at first, but with a little knowledge and practice, you will be able to confidently select a high-quality gemstone. Keep the four Cs – color, clarity, cut, and carat weight – in mind as you shop for your perfect ruby. Remember that a truly exceptional ruby will exhibit a vibrant, pure red hue, good clarity, an excellent cut, and a size that meets your needs.
