Rubies are well-known for their vibrant red color, but they can indeed appear orange under certain conditions. This variation in hue is due to the presence of trace elements and specific lighting conditions that affect the gemstone’s appearance.

What Causes Rubies to Look Orange?

Rubies are a variety of the mineral corundum, and their color is primarily due to the presence of chromium. However, when additional trace elements like iron are present, they can influence the stone’s color, giving it an orange tint. The combination of these elements can lead to rubies that range from pure red to shades of pink, purple, or even orange.

How Does Lighting Affect Ruby Color?

Lighting plays a crucial role in how we perceive the color of rubies. Under incandescent light, which has a warm tone, rubies can appear more orange or even brownish. In contrast, fluorescent lighting, which is cooler, can enhance the red tones. This change in appearance under different lighting conditions is known as pleochroism, a common characteristic in many gemstones.

Identifying Orange-Tinted Rubies

When trying to identify rubies with an orange hue, consider the following:

• Color Saturation: Look for rubies with less intense red saturation, which may appear more orange.
• Clarity and Cut: High clarity and a precise cut can influence how color is perceived, potentially enhancing orange tones.
• Lighting Conditions: Examine the ruby under various lighting conditions to see how its color changes.

Are Orange Rubies Valuable?

The value of a ruby is determined by its color, clarity, cut, and carat weight. While pure red rubies are typically more valuable, orange-tinted rubies can still be prized, especially if they possess excellent clarity and a well-executed cut. The rarity and unique appearance of orange rubies can make them desirable to collectors and enthusiasts.

Examples of Famous Orange Rubies

Though not as common as their red counterparts, some notable orange rubies have gained attention:

• The Sunrise Ruby: While primarily red, this famous gem exhibits subtle orange tones under certain lighting conditions, contributing to its allure.
• Mogok Rubies: Originating from Myanmar, some rubies from the Mogok region display an orange tint due to the unique geological conditions.
