If you were born in July, your traditional birthstone is ruby, a gemstone known for its vivid red color, long history, and strong associations with love, passion, courage, and vitality.
Ruby is more than simply a beautiful red gemstone. It is the red variety of corundum, the same mineral family that includes sapphire, and it ranks 9 on the Mohs hardness scale. That combination of color, symbolism, and durability makes ruby especially appealing for rings and other jewelry worn regularly.
Whether you are shopping for a July birthday gift or simply want to understand this gemstone better, here is what to know about the July birthstone.
What Is the July Birthstone?
The July birthstone is ruby.
Ruby is a variety of the mineral corundum. Pure corundum is colorless, while trace elements can give it different colors. Chromium is responsible for the characteristic red color of ruby.
Ruby and sapphire therefore belong to the same mineral family. The distinction is primarily based on color: red corundum is called ruby, while other gem-quality corundum colors are generally classified as sapphire.
Ruby is also one of the classic precious gemstones, alongside diamond, emerald, and sapphire.

Why Is Ruby the Birthstone for July?
Ruby has been associated with July for generations and became part of the modern standardized birthstone tradition in the early 20th century.
Its rich red color has also made it a natural symbol for qualities traditionally associated with midsummer: energy, passion, warmth, and vitality.
Historically, ruby was prized across different cultures. Ancient Indian traditions referred to ruby as a “king” among gemstones, while European traditions associated it with health, wealth, wisdom, and love.
Some historical beliefs gave ruby protective or almost magical powers. These are part of the gemstone’s cultural history rather than scientifically established properties.
Today, ruby remains July’s traditional birthstone and is commonly given for July birthdays as well as the 40th wedding anniversary.
What Does the July Birthstone Mean?
Ruby has accumulated several symbolic meanings throughout history.
Love and passion
Ruby’s intense red color has long connected it with romantic love, desire, and passion. That makes a ruby ring or necklace a particularly meaningful gift for a partner.
Courage
Ruby has also been associated with strength and courage. Historical stories from different cultures often portray ruby as a protective or empowering gemstone.
Protection
Some traditions believed ruby could protect its wearer from danger or misfortune. While there is no scientific evidence that a gemstone provides physical protection, the symbolism remains an important part of ruby’s history.
Vitality and energy
The gemstone’s bright red color has also been associated with life, energy, and strength.
For modern jewelry, these meanings make ruby especially suitable when you want a gemstone that feels bold and emotionally significant rather than understated.
What Color Is the July Birthstone?
The July birthstone is best known for its red color, but rubies can vary considerably in appearance.
Their colors can range from pinkish red to deeper, more saturated red and slightly purplish red.
The finest ruby color is generally described as a vivid, saturated red that is neither too dark nor too light. The traditional trade expression “pigeon’s blood” is associated with particularly desirable ruby color, although the term can be interpreted differently and should not be treated as a precise grading category.
Color is the most important quality factor when evaluating ruby.
A ruby that is extremely dark may lose brightness, while a very light stone may fall into the pink-sapphire category depending on the laboratory or market. Ultimately, the best color is also a matter of personal preference.
Why Are Rubies Red?
Ruby gets its red color primarily from trace amounts of chromium within the corundum crystal.
The amount and behavior of chromium, along with other factors within the gemstone, influence how intense and vivid the red appears.
Some rubies can also show red fluorescence, which may contribute to their visual appearance in certain lighting conditions.
This is one reason two rubies that appear similar at first glance can look noticeably different when viewed under different lighting.
Is Ruby a Good Gemstone for Everyday Jewelry?
Yes. Ruby is one of the more practical colored gemstones for everyday jewelry.
Ruby has a Mohs hardness of 9, making it second only to diamond on the traditional hardness scale. Corundum also has good toughness and no cleavage, which helps explain why ruby is commonly used in rings and other jewelry exposed to everyday wear.
That does not mean ruby is impossible to damage. A ruby can still chip or fracture, particularly if it has significant surface-reaching fractures or certain treatments.
If you are choosing a ruby ring for regular wear, pay attention not only to hardness but also to the gemstone’s clarity, fractures, setting, and treatment.
Are Rubies Treated?
Many rubies on the market have been treated, particularly with heat.
Heat treatment can improve a ruby’s color and appearance and is a widely encountered practice in the trade. Treatment itself does not automatically mean a ruby is poor quality.
The important point is knowing what treatment has been performed.
Other rubies may have undergone treatments such as lattice diffusion or fracture filling. These treatments can have different implications for durability, appearance, value, and care.
If you are buying a valuable ruby, ask the seller for treatment information in writing. For a significant purchase, an independent laboratory report can also help establish whether the stone is natural or laboratory-grown and identify detectable treatments.
What Should You Look for When Buying a Ruby?
Ruby buying is different from buying a diamond because ruby does not have one universal grading system equivalent to the diamond 4Cs.
Still, several factors deserve close attention.
1. Color
Start with color.
Look for a red that is attractive, lively, and appropriately saturated for your taste. Extremely dark stones can appear less bright, while very light stones may be classified differently.
2. Clarity
Don’t expect every ruby to be completely free of inclusions.
Natural rubies commonly contain inclusions, and truly inclusion-free natural rubies are extremely rare. What matters is how noticeable the inclusions are and whether they reduce transparency, brightness, or durability.
3. Cut
A good cut should make the ruby look attractive and lively.
Ovals and cushions are among the most common ruby shapes, although round, pear, marquise, emerald-cut, and other shapes are available.
Watch for a noticeable “window,” where light passes through the center of the stone instead of returning toward the viewer.
4. Treatment
Always ask whether the ruby has been heated, diffused, fracture-filled, or otherwise treated.
Two rubies with similar color and size can have very different values depending on their treatment history.
5. Lab documentation
For a higher-value ruby, independent laboratory documentation can provide useful information about whether the stone is natural or laboratory-grown and whether treatments are detectable.
Popular July Birthstone Jewelry
Ruby works particularly well in jewelry because its strong color can stand on its own.
Ruby rings

Ruby necklaces
A ruby pendant is an easy way to incorporate a birthstone into an everyday jewelry wardrobe. Simple solitaire pendants work well for understated looks, while halo or cluster designs create more visual impact.
Ruby earrings
Ruby studs are a practical choice for someone who wants a July birthstone piece that can be worn frequently without requiring a complicated styling decision.
Ruby and diamond jewelry
Ruby and diamond are a classic combination. The contrast between the bright red ruby and the colorless appearance of diamond can make both gemstones stand out.
This pairing works particularly well in rings, earrings, pendants, and anniversary jewelry.
Ruby vs. Garnet: Are They the Same?
No. Ruby and garnet can both appear red, but they are completely different gemstones.
Ruby belongs to the corundum mineral family, while garnet refers to a group of related minerals with different chemical compositions.
Their appearance can overlap, especially in darker red stones, which is why understanding the differences can be useful when shopping for red gemstone jewelry.
If you’re comparing the two, our guide to red garnet vs. ruby can help you understand how they differ in color, durability, appearance, and other characteristics.
How to Care for Ruby Jewelry
Ruby is relatively easy to care for, but the correct cleaning method can depend on treatment.
For untreated and many heat-treated rubies, warm water, mild soap, and gentle cleaning are generally suitable.
However, treated stones require more caution.
Fracture-filled, cavity-filled, or dyed rubies can be more vulnerable to certain cleaning methods and chemicals. If you do not know how your ruby has been treated, it is safer to ask a professional jeweler before using an ultrasonic or steam cleaner.
For everyday care:
- Clean ruby jewelry with warm, soapy water when appropriate.
- Use a soft brush to remove dirt around the setting.
- Avoid harsh chemicals.
- Store ruby jewelry separately from softer gemstones to prevent scratches.
- Have valuable ruby jewelry professionally inspected from time to time.
- Keep documentation about the gemstone’s treatment with your jewelry records.

Final Thoughts
Ruby is a fitting July birthstone because it combines a memorable color with centuries of history and symbolism.
Its vivid red can represent love, passion, courage, and vitality, while its 9 Mohs hardness makes it one of the more practical colored gemstones for everyday jewelry.
When choosing a ruby, don’t focus only on size. Color, clarity, cut, treatment, and durability all matter. A smaller ruby with lively color and good transparency can be far more appealing than a larger stone that looks dark or heavily included.
