how can you 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 captivated the hearts of jewelry enthusiasts and collectors alike 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 its counterfeits.

As a leading wholesale manufacturer of 925 sterling silver jewelry, Riyo Gems has a deep understanding of the intricacies of gemstone identification. In this comprehensive guide, we will delve into the various techniques and methods you can use to confidently identify a real ruby, ensuring that your jewelry investments are as authentic as they are beautiful.

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, such as chromium, that give the stone its distinctive red hue. The intensity and saturation of this color can vary, with the most valuable rubies exhibiting a deep, vivid red.

When examining a potential ruby, there are several key characteristics to look for:

Color

The color of a genuine ruby should be a rich, vibrant red, often described as "pigeon's blood" red. This color is the result of the chromium content in the stone. Rubies with a more pinkish or purplish hue are generally less valuable.

Clarity

Genuine rubies often contain inclusions, which are small imperfections within the stone. These inclusions can be seen with the naked eye or under magnification and are a natural characteristic of the gemstone. Rubies with fewer inclusions and a higher degree of clarity are more valuable.

Cut and Proportions

A well-cut ruby will have a symmetrical and proportionate shape, with a high degree of polish and brilliance. Poorly cut rubies may appear dull or lifeless, reducing their overall value.

Hardness

Rubies are a 9 on the Mohs hardness scale, making them one of the hardest gemstones. This hardness contributes to their durability and resistance to scratches and chips.

Identifying a Genuine Ruby

Now that you understand the key characteristics of a genuine ruby, let's explore the various methods you can use to identify one:

Visual Inspection

The first step in identifying a ruby is a thorough visual inspection. Examine the stone under a bright light, looking for the distinctive red color, the presence of inclusions, and the overall quality of the cut and proportions. If the stone appears too perfect or uniform in color, it may be a synthetic or imitation ruby.

Hardness Test

As mentioned earlier, rubies have a hardness of 9 on the Mohs scale. You can perform a simple hardness test by gently scratching the stone with a piece of quartz or another hard mineral. If the stone is scratched, it is likely not a genuine ruby.

Specific Gravity Test

Genuine rubies have a specific gravity (the ratio of the stone's weight to the weight of an equal volume of water) that ranges from 3.97 to 4.05. You can perform a specific gravity test by submerging the stone in a liquid with a known specific gravity, such as water or a salt solution, and observing its behavior.

Dichroscope Test

A dichroscope is a specialized tool that can help you identify the presence of chromium in a ruby, which is a key indicator of a genuine stone. When viewed through a dichroscope, a genuine ruby will display two distinct colors, often a deep red and a purplish-red.

Fluorescence Test

Rubies can exhibit a characteristic fluorescence when exposed to ultraviolet (UV) light. Genuine rubies will typically display a red or orange-red fluorescence, while synthetic or imitation rubies may have a different or no fluorescence at all.

Laboratory Certification

For the ultimate assurance of a ruby's authenticity, it is recommended to have the stone evaluated by a reputable gemological laboratory. These laboratories use advanced techniques, such as X-ray diffraction and spectroscopy, to accurately identify the stone's composition and origin.

Conclusion

Identifying a genuine ruby can be a complex process, but with the right knowledge and tools, you can confidently ensure that your jewelry investments are as authentic as they are beautiful. By understanding the key characteristics of a genuine ruby and utilizing the various identification methods outlined in this guide, you can make informed decisions and enjoy the timeless elegance of this captivating gemstone.
