How Much Are Rubies Worth?
The first time you see one of those deep, vivid red rubies in our showcases, the question usually comes right away: How much is it actually worth?
At Miro Jewelers, we make it simple. No confusing gem jargon, no guesswork, just clear, honest explanations so you understand exactly what you’re paying for and why. Whether you’re picking out a meaningful gift or shopping for an engagement ring, knowing what drives ruby value helps you shop with confidence and spot the difference between stones.
Key Takeaways:
Color is everything. The most valuable rubies are a rich, vivid red with a slight blue tint—often called “pigeon’s blood.”
Origin matters. Rubies from Myanmar (Burma) are the most prized, but Mozambique and other regions also produce high-quality stones.
Treatment affects price. Unheated rubies are extremely rare and command a premium. Heat-treated stones are common and widely accepted.
Clarity is different from diamonds. Some inclusions are normal in rubies—and can even add character—but visible flaws lower their value.
Cut and size matter. Larger, well-cut rubies are rare, and prices rise sharply as carat weight increases.

So, How Much Are Rubies Worth?
Ruby pricing really comes down to a few key factors, and each one can make a big difference. Here’s what our gemologists look at when evaluating every stone.
1. Color
Color is the biggest factor in ruby value—no question about it.
The most sought-after shade is a pure, vibrant red with a subtle blue undertone. In the trade, this is known as “pigeon’s blood” red. It’s incredibly rare, and it’s what drives top-tier ruby prices.
When evaluating color, we look at:
Hue: the actual shade of red
Saturation: how rich and intense the color appears
Tone: how light or dark the stone looks
If a ruby leans too pink, it may actually be classified as a pink sapphire, which typically lowers the price. If it’s too dark, it can lose that bright, lively glow people love.
At Miro Jewelers, we hand-select rubies that show off the richest, most balanced color possible.
2. Country of Origin
Where a ruby comes from can have a major impact on its value.
Myanmar (Burma) is considered the gold standard. Rubies from the Mogok Valley are especially famous for their rich color and natural glow in daylight. Top Burmese rubies can sell for several times more than similar stones from other regions.
Other important sources include:
Mozambique (known for vibrant, saturated reds)
Thailand
Sri Lanka
Madagascar
When a ruby’s origin is certified by respected labs like GIA or Gübelin, it can significantly increase its value. If you’re buying a higher-end stone, always ask for documentation.
3. Treatment
Treatment is one of the most important and misunderstood parts of Ruby pricing.
Most rubies on the market today are heat-treated, which is a standard, accepted process used to enhance color and clarity. These stones are still natural rubies and are widely used in fine jewelry.
However, unheated rubies with strong natural color are extremely rare and can cost two to three times as much, or even more, than treated stones.
On the other hand, heavily treated stones (like glass-filled rubies) are less valuable and may not be as durable over time.
At Miro Jewelers, we’re fully transparent about all treatments and provide lab reports so you know exactly what you’re buying.
4. Clarity
Rubies are a little different from diamonds here.
They naturally contain inclusions, and that’s completely normal. In fact, some inclusions like fine rutile needles can actually enhance a ruby’s beauty by creating a soft, glowing effect known as a “silk.”
That said:
Visible inclusions that affect appearance or durability lower the value
“Eye-clean” rubies are rare and highly desirable, especially in top color grades
Every stone we carry is carefully inspected so you know exactly what you’re getting.
5. Cut
A ruby’s cut affects both its beauty and its value.
Because high-quality rough ruby is so rare, cutters often try to preserve as much of the original stone as possible. That sometimes means proportions aren’t as perfectly symmetrical as diamonds.
A good cut should:
Show even color throughout the stone
Avoid dark or dull areas
Maximize brilliance and glow
Common ruby shapes include:
Oval
Cushion (very popular)
Round (rarer and often more expensive)
You’ll also see cabochon cuts—smooth, domed stones used in star rubies, which display a unique star-like effect called asterism. These are especially popular with collectors.
6. Carat Weight
Carat weight has a huge impact on ruby pricing.
Fine rubies over two carats are rare. Over five carats? Exceptionally rare. And as size increases, the price per carat rises dramatically, not gradually.
To give you a general idea:
1 carat rubies (heat-treated): typically $1,000–$3,000 per carat
2–3 carat, fine Burmese rubies (unheated, high quality): $30,000–$100,000+ per carat
And exceptional stones at auction can go far beyond that.
Bigger doesn’t just mean more expensive; it often means exponentially more valuable.
