What Does A Raw Ruby Look Like?

Rubies are one of the most stunning and revered gemstones in the world, symbolizing love, passion, and vitality. While most people are familiar with polished and faceted rubies seen in jewelry, raw rubies — in their natural, uncut state — look quite different.

These unrefined gemstones hold their own beauty and allure and are prized by gem collectors and enthusiasts alike. But how can you identify a raw ruby? What sets it apart from other red stones?

Introduction to Rubies: The Gemstone of Kings

Rubies have fascinated people for centuries. Known as the “king of gemstones,” rubies are part of the corundum family and are renowned for their deep red color. The stone’s color is the result of trace amounts of chromium within the mineral. Rubies have been worn by royalty, adorned religious artifacts, and even served as talismans in ancient times.

A ruby’s fiery red glow represents energy, power, and life. In modern times, it remains one of the most valuable and sought-after gemstones, especially in its finest form.

The Difference Between Raw and Polished Rubies

Before discussing the appearance of a raw ruby, it is essential to understand the distinction between raw and polished gemstones. A raw ruby is a ruby in its natural state, meaning it has not been cut, shaped, or polished. In contrast, a polished ruby has undergone treatment, such as cutting and faceting, to enhance its beauty and sparkle, making it suitable for jewelry.

While polished rubies are prized for their brilliance and precision, raw rubies possess a unique, natural charm. Their unrefined look provides insight into how these gemstones occur in nature before they are transformed into the dazzling stones we commonly see.

What Does a Raw Ruby Look Like?

Raw rubies can vary significantly in appearance, depending on the quality and size of the stone, its geographical origin, and whether any impurities are present. Here’s a breakdown of the key characteristics that define raw rubies.

1. Shape and Form

One of the most striking features of a raw ruby is its irregular shape. Unlike the uniformity of polished rubies, raw rubies typically have jagged or uneven edges and surfaces. They can appear rough and craggy, with some parts of the stone looking smooth while others remain coarse.

Hexagonal Shape: Rubies naturally form in hexagonal crystal structures. If you find a raw ruby in a perfectly preserved form, it may have a six-sided, prismatic shape with flat sides and a pointed or flat top. This hexagonal habit is distinctive to corundum minerals like rubies.

Clustered Appearance: Raw rubies may also appear in clusters of intergrown crystals. In these formations, multiple rubies may be fused together in a rough mass, making it harder to identify individual crystals.

2. Color

Color is the most defining feature of any ruby, and raw rubies are no exception. However, the color of raw rubies can be quite different from the polished gemstones seen in jewelry.

Deep Red or Pinkish-Red: The most common color associated with raw rubies is deep red, often with a slight pink or purplish tint. The highest quality raw rubies display a rich, vivid red that is commonly referred to as “pigeon blood red.” This is the most desirable and valuable color for rubies, both in raw and polished forms.

Opaque or Translucent Appearance: Raw rubies are often less transparent than their polished counterparts. Many raw rubies appear opaque, especially when they contain inclusions or impurities. Others may exhibit some translucency, allowing light to pass through but not to the same degree as a polished stone.

Uneven Color Distribution: In a raw ruby, the color may not be evenly distributed across the stone. Some areas might appear darker or lighter, depending on the stone’s mineral content. These variations give the stone a more organic and natural appearance.

3. Surface Texture

The surface of a raw ruby can range from smooth to rough, depending on the stone’s location and formation process.

Rough and Cracked: Many raw rubies have rough surfaces with visible cracks and fissures. These imperfections are normal and often disappear once the stone is polished.

Matte Finish: Unlike the shiny brilliance of a polished ruby, raw rubies tend to have a matte or dull finish. Without cutting and polishing, the surface doesn’t reflect light as brightly, making it appear more subdued.

4. Inclusions and Impurities

Inclusions are common in natural rubies, and raw stones often contain visible imperfections. These inclusions can take the form of tiny mineral deposits, cracks, or gas bubbles trapped within the stone. Some inclusions in raw rubies may look like fine silk threads or tiny needle-like structures, giving the stone a cloudy or milky appearance.

While inclusions may reduce the transparency of a polished ruby, they are common in raw stones and do not necessarily detract from their beauty or value. In fact, certain types of inclusions, such as rutile needles, can produce a desirable star-like effect known as asterism when the ruby is polished.

5. Luster

Luster refers to how a gemstone’s surface reflects light. In raw rubies, the luster can vary depending on the stone’s quality.

Vitreous to Dull Luster: High-quality raw rubies often exhibit a vitreous, or glass-like, luster, even before they are polished. This subtle shine can hint at the stone’s potential brilliance once it is cut and faceted. Lower-quality raw rubies, on the other hand, may have a duller appearance with little to no shine.

6. Size

Raw rubies come in all sizes, from small fragments to larger crystal formations. The size of a raw ruby can significantly influence its value, with larger stones typically being more expensive, especially if they display good color and clarity.

However, finding large, high-quality raw rubies is rare. Many raw rubies are small and may require cutting and polishing to enhance their appearance and value.

7. Weight and Density

Rubies are relatively dense gemstones due to their mineral composition. Even small raw rubies can feel surprisingly heavy for their size. This density is one of the factors that make rubies durable and well-suited for use in jewelry.

8. Chatoyancy and Asterism

In some raw rubies, natural inclusions can cause an optical effect known as chatoyancy, which is a reflective effect that creates a “cat’s eye” appearance. In other cases, inclusions of rutile needles can cause asterism, resulting in a star-shaped pattern on the surface of the stone. These phenomena are often more visible once the ruby is polished, but they can occasionally be seen in raw stones as well.

Identifying Raw Rubies: A Guide for Gem Lovers

For jewelry lovers and gem enthusiasts, identifying a raw ruby can be a rewarding experience. Here are some tips to help you distinguish a raw ruby from other red stones like garnet or spinel.

1. Look for the Hexagonal Shape

As mentioned earlier, rubies form in hexagonal crystal structures. If you encounter a rough red stone with a six-sided shape, it’s likely a ruby or another corundum mineral. This is one of the easiest ways to identify a raw ruby in its natural form.

2. Check the Hardness

Rubies are incredibly hard gemstones, ranking 9 on the Mohs scale of mineral hardness. You can test the stone’s hardness by scratching it with a substance of lower hardness, such as glass or steel. If the stone resists scratching, it is likely a ruby or another hard gemstone like sapphire.

3. Examine the Color

Raw rubies typically display a rich, deep red color. If the stone has a vibrant, intense red hue, there’s a good chance it’s a ruby. However, be cautious, as other red gemstones like garnet and spinel can also appear similar in color.

4. Test for Transparency

Raw rubies are often opaque or translucent, but if you hold the stone up to a light source, you may see some light passing through. This can help you differentiate between a raw ruby and other red stones, which may be more transparent or have different optical properties.

5. Consult a Gemologist

If you’re still unsure whether a stone is a raw ruby, it’s best to consult a professional gemologist. They can perform tests using specialized equipment to confirm the stone’s identity and assess its quality.

Where Are Raw Rubies Found?

Raw rubies are found in several locations around the world, with some regions known for producing higher-quality stones than others. The most famous ruby mines are located in Myanmar (formerly Burma), which produces some of the finest rubies known as Burmese rubies. Other notable ruby sources include:

Thailand: Known for producing dark red rubies with a brownish tint.

Sri Lanka: Produces lighter-colored rubies, often with a pinkish hue.

Mozambique: A more recent source of high-quality rubies with vivid color.

Madagascar: Known for producing both pink sapphires and rubies.

The Value of Raw Rubies

Raw rubies, like polished ones, can vary greatly in value depending on their size, color, clarity, and origin. High-quality raw rubies with deep red color and minimal inclusions are more valuable, even in their uncut form.

Smaller, lower-quality raw rubies with significant inclusions or dull color are less valuable but may still hold appeal for collectors or those interested in lapidary (gem-cutting).

Conclusion

Raw rubies offer a fascinating glimpse into the natural beauty of gemstones before they undergo the transformation into polished jewels. Their rough, unpolished appearance gives them a unique character, with irregular shapes, deep red hues, and the potential for stunning optical effects.

For jewelry lovers, raw rubies represent the essence of nature’s artistry, capturing the fiery beauty that has made rubies one of the most beloved gemstones throughout history. Whether you’re a collector, a gem enthusiast, or someone new to the world of gemstones, raw rubies hold a timeless allure that is sure to captivate your imagination.
