how to tell if a ruby is real ?

In the world of gemstones, the ruby stands out as a true symbol of elegance, rarity, and prestige. Its captivating crimson hue has enchanted jewelry enthusiasts and collectors for centuries. However, with the rise of synthetic and imitation rubies, it has become increasingly important to be able to distinguish a genuine ruby from a counterfeit.

As a leading wholesale manufacturer of 925 sterling silver jewelry, Riyo Gems has extensive experience in the world of gemstones. In this comprehensive guide, we will share our expertise and provide you with the essential knowledge to identify a real ruby, ensuring you make informed and confident purchases.

Understanding the Characteristics of a Genuine Ruby

Rubies are a variety of the mineral corundum, which is composed of aluminum oxide. What sets genuine rubies apart is the presence of trace elements, primarily chromium, which give the gem its distinctive red color. The intensity and purity of this red hue are key factors in determining the value and quality of a ruby.

Color

The color of a genuine ruby can range from a deep, vivid red to a pinkish-red, depending on the concentration of chromium. The most valuable rubies are those with a pure, intense red color, often referred to as "pigeon's blood" rubies. These rare and highly sought-after gems are the benchmark for quality and command the highest prices in the market.

Clarity

Genuine rubies, like other gemstones, may contain inclusions, which are small imperfections within the stone. These inclusions can provide valuable information about the ruby's origin and authenticity. While some inclusions are acceptable, a high degree of clarity is generally preferred, as it indicates a higher-quality gem.

Cut and Proportions

The cut and proportions of a ruby can greatly impact its appearance and value. A well-cut ruby will have a symmetrical and balanced shape, with a high degree of brilliance and fire. Poorly cut rubies may appear dull or lifeless, diminishing their overall appeal.

Carat Weight

The carat weight of a ruby is a measure of its size. Larger rubies are generally rarer and more valuable than smaller ones, all else being equal. However, it's important to note that the quality and characteristics of the ruby are more important than its size when determining its true worth.

Identifying Synthetic and Imitation Rubies

With the advancements in technology, it has become increasingly challenging to distinguish a genuine ruby from a synthetic or imitation one. Synthetic rubies are created in a laboratory, while imitation rubies are made from other materials, such as glass or cubic zirconia, to mimic the appearance of a real ruby.

Examining the Inclusions

One of the most reliable ways to identify a genuine ruby is by examining its inclusions under a microscope or a jeweler's loupe. Genuine rubies often have unique inclusion patterns, such as "silk" (fine, needle-like inclusions) or "fingerprints" (irregular, cloud-like inclusions), which are not found in synthetic or imitation stones.

Checking the Refractive Index

The refractive index of a gemstone is a measure of how light bends as it passes through the material. Genuine rubies have a specific refractive index range, which can be tested using a gemological instrument. Synthetic and imitation rubies may have a different refractive index, which can help distinguish them from the real thing.

Observing the Fluorescence

When exposed to ultraviolet (UV) light, genuine rubies may exhibit a characteristic fluorescence, which is the emission of light from the stone. The type and intensity of the fluorescence can provide valuable clues about the ruby's authenticity and origin.

Consulting a Gemological Laboratory

For the most accurate and reliable identification, it is recommended to have a ruby evaluated by a reputable gemological laboratory. These experts have access to advanced testing equipment and techniques that can conclusively determine the authenticity of a gemstone.
