July Birthstone: Ruby Meaning, History & Buying Guide

No gem says passion quite like the ruby. Its deep, glowing red has crowned kings, adorned warriors, and stood for love and courage across every great civilization. If someone you love was born in July, this is their stone — and it happens to be one of the most durable and treasured gems in existence. Here's everything worth knowing about the July birthstone.

What Is July's Birthstone?

The king of gems: ruby.

July's birthstone is ruby, the vivid red variety of the mineral corundum. According to the GIA, ruby has been one of the most prized gems throughout history, valued for its intense color and remarkable hardness. Long called the "king of gems," it remains a symbol of love and power to this day. Explore it in our July birthstone jewelry.

Ruby Meaning & Symbolism

The stone of passion and courage.

Ruby's fiery red has always been linked to the strongest human emotions. Across cultures it has symbolized:

• Passion and love — the ultimate stone of the heart and desire.
• Courage and vitality — warriors once wore rubies into battle for strength.
• Power and success — a gem of royalty, prosperity, and confidence.
• Protection — believed to guard the wearer from harm and misfortune.

In some astrological traditions, ruby is tied to the Sun and thought to bring vitality and confidence — beliefs that are part of folklore rather than proven effects. However you read it, ruby's message is one of bold, passionate energy.

What Ruby Actually Is

Sapphire's red sibling.

Ruby is a variety of corundum (aluminium oxide) — the very same mineral as sapphire. In fact, the only difference is color: red corundum is ruby, and every other color of gem corundum is a sapphire. Ruby gets its red from traces of chromium, and the more chromium, the more intense the red (and often the more fluorescent glow). It rates 9 on the Mohs scale, making it the second-hardest natural gem after diamond — a big part of why it's so well suited to jewelry meant to last generations.

Is There a Second July Birthstone?

A common question — simply answered.

In modern birthstone lists, ruby is July's only official birthstone. A few older or traditional lists mention alternatives like onyx, carnelian, or turquoise, but today ruby stands alone for July. If you'd like to see a month that genuinely has several stones, our June birthstone guide covers pearl, alexandrite, and moonstone.

History & Lore

Four thousand years of reverence.

The name "ruby" comes from the Latin ruber, simply meaning "red." In ancient Sanskrit, ruby was called ratnaraj — "king of precious stones." Warriors in Burma believed rubies made them invincible, some even embedding stones beneath their skin. Medieval Europeans wore ruby for health, wealth, and protection. Through every era, ruby's blood-red color has stood for life force itself — a story we trace further in our history of gemstones.

Quality & Value: How to Buy a Ruby

Color is everything.

Ruby is judged on the four Cs, but with color as the overwhelming priority:

• Color — the most prized shade is a vivid, pure red to slightly purplish red known as "pigeon's blood." Too dark or too pink lowers value.
• Clarity — nearly all rubies have inclusions; eye-clean stones with strong color are rare and valuable.
• Cut — a good cut maximizes that glowing color and hides inclusions.
• Carat — large fine rubies are exceptionally rare, so price rises steeply with size.

An honest note on treatment and rarity: most rubies are heat treated to improve color and clarity — a standard, accepted practice that keeps them affordable. Untreated, top-color rubies (historically from Myanmar, with Mozambique now a leading source) are genuinely rare and can rival diamonds in price. Lab-created rubies offer the same look and durability for far less. Reputable sellers always disclose treatment, so ask.

Durability & Care

One of the toughest colored gems.

At Mohs 9, ruby is wonderfully durable and one of the best colored stones for an everyday ring. Caring for it is easy:

1. Clean with warm soapy water and a soft brush; rinse and dry. Ultrasonic cleaners are usually safe for untreated or heat-treated rubies, but avoid them for fracture-filled stones.
2. Avoid harsh chemicals — remove ruby jewelry before heavy cleaning or swimming in chlorinated water.
3. Store separately — at Mohs 9, ruby can scratch softer gems, so give it its own space.
