Leo Birthstone: Colors, Stones and Meanings

The Leo birthstone is Ruby for July-born Leos and Peridot for August-born Leos. Sardonyx and Onyx are also recognized Leo stones across traditional birthstone systems. Leo runs from July 23 to August 22, placing the sign across two separate birthstone months. This guide covers every Leo birthstone, their colors, exact meanings, lucky stones, and which gemstones Leo should avoid.

What is the Leo Birthstone?

Leo has two primary birthstones: Ruby and Peridot. Ruby is the official July birthstone, and Peridot became the modern primary August birthstone when confirmed by the American Gem Society in 1912.

Sardonyx is the oldest traditional Leo birthstone, with documented use spanning over 4,000 years. Onyx is also widely associated with Leo as a zodiac stone across multiple gemstone traditions.

Leo is ruled by the Sun. Both Ruby and Peridot carry direct solar associations, which is why they align closely with the sign's energy profile in both Western and Vedic gemstone traditions.

Leo Star Sign Birthstone by Month

July Leo Birthstone: Ruby

Ruby is the birthstone for Leos born from July 23 through July 31. It ranks among the most valuable gemstones in the world. Ruby forms from chromium-rich corundum deep within the Earth's crust, a geological combination rare enough that gem-quality stones remain scarce globally.

Ancient Egyptians called it the "gem of the sun" and mined it on the island of Zabargad in the Red Sea. Peridot forms in the Earth's upper mantle and has also been found inside pallasite meteorites.

Peridot at a glance:

• Color: Olive green to lime green; intensity determined by iron content

• Hardness: 6.5 to 7.0 Mohs

• Meaning: Growth, abundance, clarity, balance

• Formation: Earth's upper mantle; one of very few gems to form in the mantle layer

• Notes: Also known as "evening emerald" because it maintains its glow under artificial light
