Are Rubies Pink? Unraveling the Red vs. Pink Conundrum in the Gemstone World
The short answer is: sometimes. It’s more nuanced than a simple yes or no. While rubies are inherently known for their red color, the specific shade and intensity play a crucial role in determining whether a gemstone is classified as a ruby or a pink sapphire. Color, saturation, and even market perception all contribute to this fascinating debate. Let’s delve deeper into this colorful world!
The Ruby Spectrum: Red with Nuances
What Defines a True Ruby?
Traditionally, a ruby is defined as a corundum gemstone with a dominant red hue. Corundum is a mineral composed of aluminum oxide. Trace elements within the corundum crystal are responsible for the gemstone’s color. In the case of rubies, it’s chromium that gives them their signature red. The intensity of the red depends on the amount of chromium present.
The finest rubies exhibit a vibrant, pure red to slightly purplish-red color. These command the highest prices in the market. However, rubies can also have undertones of orange, pink, or purple. The tricky part is determining when those undertones become so dominant that the gem is no longer considered a ruby.
The Pink Sapphire Distinction
Here’s where the lines blur. Gemstones that are corundum and exhibit a pink color, caused by chromium trace elements, are classified as pink sapphires. The deeper the pink, the more chromium is present. However, there’s a subjective element involved: what one gemologist considers a “dominant red hue,” another might see as a “strong pink.”
In the United States, the Gemological Institute of America (GIA), a leading authority in gemology, plays a crucial role. The GIA classifies corundum as a ruby only if it has a “dominant” red hue. Otherwise, it’s a pink sapphire. This distinction, however, is not universally accepted worldwide, and historical and cultural variations exist.
The Impact of Tone and Saturation
The tone and saturation of the color are also essential. A ruby’s color must be neither too dark nor too light to be considered of the finest quality. Saturation refers to the intensity of the color, while tone refers to its lightness or darkness. A highly saturated, medium-toned red is generally considered ideal. A light pink with low saturation would almost certainly be classified as a pink sapphire. On the other hand, even a slightly pinkish-red with high saturation might still qualify as a ruby.
Value and Rarity: Ruby vs. Pink Sapphire
Generally, rubies are more valuable and expensive than pink sapphires. This is due to their rarity and historical significance. Rubies, especially those with a deep, blood-red color, have always been highly prized. However, a vivid pink sapphire with exceptional clarity and size can command a significant price, sometimes even rivaling that of a lower-quality ruby. The price depends on a few factors: the color saturation, cut, clarity, and carat size.
Pink sapphires were once considered far rarer, primarily found in Sri Lanka and Myanmar. The discovery of pink sapphires in Madagascar in the late 1990s increased their availability, but fine-quality pink sapphires remain rare and valuable.
The Allure of Pigeon’s Blood Rubies
One of the most coveted types of rubies is the “pigeon’s blood” ruby. This term refers to rubies with a specific intense red color with a slight purplish hue and a vivid fluorescence. This color is particularly associated with rubies from Myanmar (formerly Burma). This particular type of ruby can be far more expensive than any pink sapphire.
FAQs: Deep Diving into Ruby Colors
1. What color is a real ruby?
The finest ruby has a pure, vibrant red to slightly purplish-red color. Pure red colors generally command the highest prices.
2. Which is more valuable: a pink sapphire or a ruby?
Generally, rubies tend to be more valuable, but a high-quality, vividly colored pink sapphire can be very expensive.
3. Can a sapphire be pink?
Yes, pink is one of the rarest sapphire colors. It’s caused by trace amounts of chromium within the corundum crystal.
4. Are pink sapphires considered rubies?
The GIA classifies corundum gems with a “dominant” red hue as rubies. All other corundum is sapphire.
5. How rare is a pink sapphire?
Pink sapphires are considered quite rare, though their availability increased after the discovery of deposits in Madagascar.
6. What is the rarest color of ruby?
Pure red rubies are the rarest because they require a lot of chromium but very little iron and titanium.
7. Why do my rubies look pink?
If a ruby appears pink, it indicates a lower concentration of chromium and a possible presence of iron and titanium.
8. Can natural rubies look pink?
Yes, natural rubies can appear pink, especially if the chromium levels are low.
9. What are pink rubies called?
Stones with low levels of chromium are typically called pink sapphires, not rubies.
10. What stone is often mistaken for a ruby?
Spinel has historically been mistaken for ruby and sapphire.
11. How can you tell a good ruby?
Color is the most significant factor. A good ruby has a pure, vibrant red to slightly purplish-red color.
12. Why are some rubies so cheap?
Cheap rubies are often highly enhanced, lab-created, or from regions known for lower-quality stones.
13. Is a pinkish ruby valuable?
Pinkish rubies can be valuable, ranging from $1,000 to $10,000 per carat, depending on the red saturation.
14. What is the difference between pink sapphires and rubies?
Ruby is typically a deep red, while pink sapphire is a light to medium pink. The difference comes from the level of chromium within the crystal structure of the gemstone.
15. How can I tell if I have a pink sapphire?
One method is to check how quickly the stone “defogs” with your breath, however the best method is to have it reviewed by a certified gemologist.
Understanding Gemstone Treatments and Enhancements
It’s important to note that many rubies and sapphires on the market have undergone treatments to enhance their color and clarity. Heat treatment is a common practice that can improve the color of a gemstone. These treatments must be disclosed, as they impact the value of the stone.
Synthetic Rubies and Sapphires
Synthetic rubies and sapphires are also readily available and are significantly less expensive than natural stones. These stones are created in a laboratory and have the same chemical composition and physical properties as their natural counterparts. While they may look identical to the untrained eye, they lack the rarity and unique characteristics that make natural gemstones so desirable. An interesting fact is that all rubies fluoresce, whether mined or created in a lab, since natural and synthetic ruby gemstones have the same chemical composition and physical properties.

Conclusion: Embrace the Beauty of the Spectrum
Ultimately, whether a gemstone is classified as a ruby or a pink sapphire depends on a combination of scientific analysis and subjective judgment. Both are beautiful and valuable gemstones in their own right. Understanding the nuances of color, saturation, and market perception allows you to appreciate the full spectrum of beauty within the world of corundum.
