July Birthstone
Ruby
The king of precious stones. A gem of passion, protection, and fire.
Quick answer: The birthstone for July is Ruby.
Ruby is both the modern and traditional birthstone for July, known for its intense red color, exceptional hardness, and long-standing reputation as one of the four precious stones.
What Is the Birthstone for July?
The July birthstone is ruby. Called "ratnaraj" in ancient Sanskrit, meaning "king of precious stones," ruby is one of the four precious gemstones alongside diamond, emerald, and sapphire. It is a variety of the mineral corundum, colored red by trace amounts of chromium.
The name "ruby" comes from the Latin ruber, meaning "red." All other colors of corundum are classified as sapphire. Rubies have been treasured by royalty for centuries, from Indian maharajas to European monarchs.
Today ruby is among the most valuable gemstones on Earth. Fine rubies routinely sell for higher prices per carat than equivalent-quality diamonds, making ruby a strong July birthday gift.

Ruby Colors & Varieties
While all rubies are red corundum, origin, color nuance, and special optical effects create distinctive varieties:
Burmese (Myanmar)
Pigeon's Blood Red
The world standard. A pure red with a blue hint and strong fluorescence that no other source replicates.
Mozambique
Rich Purplish-Red
A major modern source producing gems that rival Burmese quality, with deep red color and good transparency.
Thai
Dark Garnet Red
Darker, brownish-red tones with less fluorescence. Often cleaner and available in larger sizes.
Star Ruby
Asterism on Red
Displays a six-rayed star floating across the surface, caused by rutile needle inclusions. Rare in fine quality.
Pink Ruby
Light Pinkish-Red
Sits at the border between ruby and pink sapphire. Lighter in tone and often more affordable.
Treated Ruby
Enhanced Red
Heat treatment is common and accepted. Glass-filled and diffusion-treated rubies are more affordable but require different care.
Why Is Ruby the July Birthstone?
Ruby's link to July comes from the stone's old connection to the sun, fire, and the peak of summer. July is the hottest month in much of the Northern Hemisphere, and ruby has long been associated with heat and vitality. Ancient cultures believed rubies held an inner fire that could not be extinguished.
The modern birthstone list was standardized in 1912 by the American National Association of Jewelers (now Jewelers of America). They formalized ruby as the July birthstone, a choice that followed centuries of tradition. Ruby had long appeared on historical birthstone lists, including those tied to the Breastplate of Aaron and early Hindu astrological charts.
Ruby connects to both July zodiac signs. Cancer values its protective, nurturing energy and emotional strength. Leo connects with ruby's confidence, leadership, and passion.
The History of Ruby
Ruby has been valued for thousands of years. In ancient India, where it was first mined, ruby was called "ratnaraj," meaning king of precious stones. Hindu texts describe ruby as the most precious of all gems, and ancient Indians believed that offering rubies to Krishna would ensure rebirth as an emperor.
Burmese warriors had one of history's strangest relationships with ruby. They inserted the gemstones into their flesh before battle, believing that rubies embedded in the body (not just worn) would make them invincible. The Mogok Valley in Myanmar has produced the world's finest rubies for centuries, with the best "pigeon's blood" stones reserved for the Burmese monarchy.
In medieval Europe, rubies adorned the crowns and regalia of kings. They were believed to darken when danger approached and to restore their color once the threat passed. Ruby was also thought to cure blood diseases, calm anger, and resolve disputes.
In 1960, the first laser was created using a synthetic ruby crystal. Ruby's chromium atoms (the same element that gives the stone its red color) proved ideal for producing coherent light. Today, beyond the Mogok Valley, significant ruby deposits are mined in Mozambique, Thailand, Sri Lanka, Vietnam, Madagascar, and Tanzania.

🌍Where Ruby Is Found
Ruby is mined across several continents, and each source produces stones with a distinctive character:
How to Care for Ruby Jewelry
Ruby is one of the most durable gemstones, but proper care ensures it stays brilliant for generations:
Clean ruby jewelry with mild soap and warm water using a soft brush.
Ultrasonic cleaners are generally safe for untreated rubies.
Steam cleaning is generally safe for untreated rubies.
Avoid exposure to harsh chemicals.
Natural rubies are heat resistant.
Store separately to prevent scratching other gemstones.
While rubies are durable (9 on the Mohs scale), they can still be chipped by hard blows, so remove ruby jewelry during vigorous activities.
If your ruby has been treated (especially glass-filled), avoid ultrasonic cleaners, steam cleaners, and harsh chemicals.
How to Choose Ruby Jewelry
When shopping for ruby jewelry, color matters most. The finest rubies show a vivid, saturated red with no brown or orange undertones. A slight blue hint (the hallmark of "pigeon's blood" color) is the most prized trait.
- 1. Color first: Vivid, saturated red is most desirable. Avoid stones that are too dark (nearly black) or too light (closer to pink sapphire).
- 2. Clarity: Some inclusions are expected in natural rubies. Eye-clean stones are rare and carry a big premium.
- 3. Cut: A well-cut ruby maximizes brilliance and color saturation. Oval, cushion, and round are the most popular shapes.
- 4. Treatment disclosure: Most rubies are heat-treated. This is accepted and should be disclosed. Glass-filled rubies are much less valuable and require different care.
Fascinating Facts About Ruby
Ruby and sapphire are actually the same mineral (corundum). The only difference is color—ruby is red corundum, while all other colors of corundum are classified as sapphires.
The Sunrise Ruby, a 25.59-carat Burmese ruby, sold for $30.3 million in 2015, setting a world record price for a ruby and a record price-per-carat for any colored gemstone.
The world's first laser was created using a synthetic ruby crystal in 1960. Ruby's chromium atoms, which give the stone its red color, also make it perfect for generating the coherent light needed for lasers.
The Liberty Bell Ruby, carved from a single 8,500-carat ruby, was once the largest mined ruby in the world. Sculpted into a miniature Liberty Bell with 50 diamonds, it was stolen in a heist in 2011 and has never been recovered.
