Look at a picture of a ruby and you’ll see red. Obviously. But if you’ve ever spent time in a high-end jewelry boutique or a gemological lab, you know that "red" is a massive understatement. It’s a whole spectrum.
Some rubies look like a drop of pigeon blood on a white plate. Others look like a diluted raspberry soda. Honestly, most people searching for a high-quality picture of a ruby are actually looking for an ideal—a digital representation of a stone that might not even exist in nature without a little help from a lab or a very clever photographer.
What You’re Actually Seeing in That Ruby Photo
When you see a professional image of a gemstone, you aren't just looking at a rock. You're looking at a carefully choreographed dance of light. Rubies are "pleochroic." This basically means the stone shows different colors depending on which angle you view it from. In one direction, it’s a purplish-red; in another, it’s a slightly orangey-red. A single picture of a ruby can’t capture that movement, so photographers have to choose the "face-up" color that looks best, often hiding the less desirable undertones.
Then there’s the fluorescence.
Most rubies, especially those from Myanmar (the old Burma), contain high levels of chromium and very little iron. When UV light hits them—even the UV present in natural sunlight—they literally glow. They fluoresce. It’s like the stone is plugged into a battery. If you see a picture where the ruby looks like it’s emitting its own internal light, that’s not just Photoshop. It’s the chromium reacting. However, many modern images over-saturate this effect to hide "extinction," which are those dark, dead black spots you see inside a gem when the cutting isn't quite right.

The Problem with Digital Color Accuracy
Color is the most important factor in a ruby's value, but it's the hardest thing to capture on a screen. You’ve probably noticed that a ruby looks different on your iPhone than it does on a MacBook or a printed catalog.
Gemologists use specific terms like hue, tone, and saturation.
A "Pigeon’s Blood" ruby is the gold standard. But here’s the kicker: that term is used way too loosely now. Swiss labs like SSEF or GUBELIN have very strict criteria for what earns that "Pigeon's Blood" trade name on a certificate. A picture of a ruby online might claim to be this top-tier color, but without a lab report, it's just marketing. Real experts look for a "vivid" saturation and a "medium-dark" tone. If it’s too light, it’s technically a pink sapphire. If it’s too dark, it looks like a garnet—garnet red is "sleepy" and brownish, whereas ruby red should be "electric."
Why a Picture of a Ruby Can Be Deceptive
Cameras hate red. It’s a known thing in photography. Red tends to "blow out" on digital sensors, losing all the detail in the facets. To get a realistic picture of a ruby, a photographer usually has to underexpose the shot and then manually pull the detail back in.

If you see a photo where the red looks like a solid block of color with no facets visible, it’s a bad photo. Or it’s a fake stone.
Inclusions: The "Silk" Mystery
If you zoom in on a high-resolution picture of a ruby, you might see tiny, needle-like structures. This is "silk," which is actually tiny crystals of rutile. Counter-intuitively, you want to see some of this. Silk proves the stone is natural and hasn't been over-heated to the point of melting its internal character. It also scatters light, giving the ruby a soft, velvety glow that synthetic stones totally lack.
Synthetics often look too perfect in pictures. If a ruby is the size of a postage stamp, has zero inclusions, and costs fifty bucks, it’s flame-fusion synthetic corundum. It's still a ruby, chemically, but it’s grown in a factory in a few hours rather than in the earth over millions of years.
Treatment: The Secret Behind the Beauty
Let’s be real: about 95% of the rubies on the market are heat-treated. This is a standard industry practice. They stick the stones in a furnace at temperatures approaching 1,800 degrees Celsius to dissolve inclusions and improve color.

A picture of a ruby that hasn't been heated is rare and expensive. We're talking "auction house" expensive. Then there’s "glass filling." This is where low-grade, cracked rubies are filled with lead glass to make them look transparent. In a photo, these can look amazing. In person, they’re fragile and worth almost nothing. You can often spot them in a photo if you see a "blue flash" or "yellow flash" inside the cracks when the light hits it at a specific angle.
How to Judge Quality from an Image
If you are looking at pictures because you're planning to buy, you need to be a bit of a detective. Look for a video. A static picture of a ruby is a lie of omission. A video shows "scintillation"—the way the sparkles move.
- Check the edges: If the facets look rounded or fuzzy, the stone might be a soft imitation like glass or red spinel (though spinel is beautiful in its own right).
- Look for "Windowing": If you can see straight through the center of the stone to the background behind it, the cut is too shallow. The light is leaking out the back instead of reflecting to your eye.
- The "Tilt Test": A good photo series should show the stone tilted. This reveals the "extinction" (black areas) and whether the color holds up from the side.
Real-World Examples of Famous Rubies
Think about the Sunrise Ruby. It’s a 25.59-carat Burmese stone. When you see a professional picture of a ruby of that caliber, the red is so saturated it almost looks purple. It sold for over $30 million. On the other end, you have the Liberty Bell Ruby, which was carved. Carvings don't rely on facets, so the photos of them focus on the luster of the surface rather than the internal fire.
The way we photograph these stones has changed, too. In the early 1900s, gem photos were often hand-tinted or used very primitive color film that made everything look slightly orange. Today, we use "macro stacking," where a camera takes 50 different photos at different focus points and merges them into one perfectly sharp image. It’s hyper-realistic, sometimes to a fault.
Where to Find Authentic Imagery
If you want to see what a ruby actually looks like without the sales pitch, stay away from Pinterest or stock photo sites. Go to the GIA (Gemological Institute of America) website or look at the "sold" listings on Sotheby’s or Christie’s. These organizations use neutral lighting setups (usually D65 "daylight" equivalent) to ensure the color in the picture of a ruby is as close to the physical stone as humanly possible.
Actionable Steps for Evaluating Ruby Images
- Request a "Hand Shot": If you're buying, always ask for a photo of the stone sitting between two fingers in natural, indirect sunlight. Jewelers call this the "truth shot." It removes the fancy studio lights and shows how the stone will actually look on your hand.
- Compare against a white background: A ruby photographed on a black background will always look more dramatic and saturated. A white background reveals the true "tone" and shows if the stone is secretly too dark or "inky."
- Check for the Lab Report Number: A reputable seller will often include a photo of the stone next to its GIA or AGL report. Match the dimensions on the report to the stone in the photo to ensure they aren't swapping it for a cheaper version.
- Ignore the "Glow": Don't be seduced by a photo where the stone seems to be glowing neon red. That’s often the result of a photographer using a UV torch specifically to trigger fluorescence, which isn't how the stone will look in an office or a restaurant.
When you're browsing, remember that a ruby is a piece of history. It’s aluminum oxide with a bit of chromium that survived a journey from deep in the crust to the surface. A picture is just a snapshot of one moment in that journey. To truly understand a ruby, you have to see how it handles the light as it moves, shifting from that deep, bloody red into the bright, fiery pinks that have made it the "King of Gems" for centuries.
