Libra Birthstone: Opal, and the Green Stone Kunz Actually Named
The Libra birthstone is opal in the modern list, with peridot as the traditional choice. Opal holds every color at once, one stone for a sign that sees every side of a thing. Peridot, the old evening emerald, brings the steady green that helps a Libra finally decide.
Why Opal for a Sign That Weighs Every Side?
Venus rules Libra in this tradition, and opal's shifting colors are read as a match for that rulership by convention, not evidence. The pairing makes no claim about your actual personality, and none about any effect opal itself produces.
Libra is cardinal air, ruled by Venus, and organized around beauty, fairness and the people you do life with. Opal is the modern Libra stone because it holds every color at once and refuses to commit to one, which is the Libra experience of any argument. No two opals are the same, and the color moves with the angle you look from. Venus puts Libra in charge of taste and partnership, and opal is the most visually complicated stone anybody wears. The traditional stone, peridot, does the opposite job. One green, the same green from every angle, offering the decisiveness a Libra sometimes cannot find alone. Older tradition also credits peridot with keeping nightmares and enchantment away, which reads today as a stone for boundaries, so keeping the peace stops costing you everything you wanted.
Which Gemstone Belongs to Libra?
History and Lore
Rome ranked opal at the top. The name reached English through the Latin 'opalus,' probably from the Sanskrit 'upala,' meaning precious stone. Pliny the Elder wrote that a single opal held the fire of ruby, the brilliance of amethyst and the sea-green of emerald all at once.
- Empress Josephine owned an opal called The Burning of Troy. It vanished after her death in 1814 and has never surfaced again.
- Queen Victoria gave opals to each of her daughters as wedding presents, keeping the stone in fashion across her whole reign.
Correspondences
Crystal practice files opal under these correspondences, a traditional association. Use it to decide where you keep opal and which intention you set with it.

Traditional Meanings
- Traditionally believed to enhance creativity, inspiration, and imagination.
- In ancient Roman tradition, opal was considered the most precious gem and a symbol of hope and purity.
Opal has held these meanings in folklore since long before modern chemistry existed, and no chemistry test has confirmed them since.
Peridot: The Traditional Libra Birthstone
This guide uses Opal as the modern Libra stone because most of the sign falls in October, whose standardized monthly list includes Opal. Peridot comes from a separate, older stream of zodiac-gem associations, which varied by place and period. Peridot's tie to Libra is an older custom, one the 1912 committee did not include. The green stone the ancients could only find after dark, and the modern August birthstone.
Peridot added warmth where opal added wonder. Where opal mirrors Libra's appreciation of beauty and multiple perspectives, peridot, the 'evening emerald,' was believed to dissolve resentment and encourage honest relationships. Libra seeks harmony but can suppress personal needs to keep the peace; peridot's association with self-worth and emotional clarity addresses that specific vulnerability.
- Many of Cleopatra's famous 'emeralds' are now believed to have been peridots from Zabargad island. The Egyptians worked that island for over 3,500 years, posting guards with orders to kill trespassers.
- Ancient Romans called peridot 'evening emerald' because its green color did not darken under lamplight the way true emerald does.
- A peridot from Zabargad is on display at the Smithsonian National Museum of Natural History, one of the largest ever cut.

Do Rose Quartz and Lapis Lazuli Work for Libra?
Beyond the primary and traditional birthstones, two additional gems have strong associations with Libra in crystal healing practice. These are not standardized monthly birthstones, but they complement opal well in both color and traditional symbolism.
Rose Quartz
Rose quartz's gentle love energy aligns with Venus-ruled Libra's natural orientation toward partnership, harmony, and aesthetic beauty.
Lapis Lazuli
Lapis lazuli's deep blue wisdom energy helps indecisive Libra make clear judgments, and it backs the leadership expected of a cardinal sign.

How Should You Wear the Libra Birthstone?
The best way to wear a birthstone is whatever way you will actually put it on every day. That said, some settings and combinations bring out opal’s best qualities better than others.
Chakra, planetary and energy notes in this section describe crystal-practice tradition, not a proven physical or medical effect.
- Wear opal in earrings or a pendant. It is a delicate stone and it is safest off your hands.
- Choose a lapis lazuli statement necklace for occasions that call for confident decisions; the stone's deep blue has been a symbol of authority since ancient Egypt.
- Layer a rose quartz bracelet with a peridot bracelet for a Venus-energy stack that supports Libra's love of beauty and partnership.

The Word Kunz Actually Used for Libra's Green Stone
Opal is Libra's modern stone and nothing rivals it there. The traditional pick is where the tables pull apart, and one of those splits is worth slowing down for.
Chrysolite named a whole family, and this page names the one inside it
Kunz's zodiac table gives Libra chrysolite, not peridot by name. In older usage chrysolite covered a run of yellow-green stones, and peridot was usually, though not always, the one a writer meant by it. This page prints peridot because it is the specific stone the word most often pointed at. The older table names the wider group. This page names the stone in your hand.
Kunz's Libra sits a day later on both ends
The modern chart runs Libra from September 23 to October 22. Kunz's table shifts the whole window later, to September 22 through October 23. Born on September 22 or October 23, the two systems even disagree about whether you count as a Libra at all.
Half your sign, and the month chart names a third stone
Opal is Libra's zodiac stone from end to end. The monthly system is less tidy. Libra opens inside September, and September's monthly stone is sapphire, so a Libra born before the 30th gets sapphire from the calendar list and opal from the zodiac one.
Where the modern stone comes from: Libra runs into October, so it inherits October's opal by the same rule every sign on this site follows. Pavitt's 1914 Libra chapter names opal too, alongside coral and lapis lazuli, making this one of only two signs where the modern column and the 1914 tradition meet. the sign-by-sign comparison →
Libra Birthstone: Frequently Asked Questions
These common questions cover the Libra birthstone, its color, monthly overlap, and how people actually wear it. The sections above carry the lore and the correspondences behind the short answers.
What is the birthstone for Libra?
The modern Libra birthstone is opal, famous for holding every color at once. The traditional one is peridot, a steady green tied to harmony and protection.
Is opal bad luck?
No. The bad-luck story starts with Sir Walter Scott's 1829 novel Anne of Geierstein and nowhere earlier. Rome treated opal as the luckiest gem there was, a symbol of hope. One novel undid two thousand years of good press.
How do I care for an opal ring?
Never soak an opal and never let it bake. No salt water, no overnight bath, no sunny windowsill, no hot car. Those are exactly the things a cleansing ritual will tell you to do, and an opal that dries out cracks from the inside where nothing can reach it. Wipe it with a damp cloth and keep it somewhere with a little moisture in the air.
Why does Libra share peridot with Leo?
Different astrological traditions assign stones differently. Leo's peridot connection is solar (modern assignment), while Libra's peridot connection is traditional, rooted in the stone's associations with harmony and balance, both core Libra values.
Is the Libra birthstone the same as the October birthstone?
They match closely. Opal is October's monthly birthstone and the modern Libra stone; tourmaline is October's other monthly option. Libra runs September 23 to October 22, so early-Libra birthdays in September fall under sapphire by month, while opal covers the sign by zodiac.
What is Libra's lucky stone?
Venus rules Libra, so rose quartz and lapis lazuli often appear as its lucky stones in crystal tradition: one for love and partnership, one for clear judgment. As with all such associations, this is cultural belief, so let personal taste guide your pick.
Is opal a good everyday stone for Libra?
Opal likes earrings and pendants far more than it likes a daily ring, because a ring is where every knock lands. If you want one Libra piece for every day, the traditional stone, peridot, is much more forgiving.
Opal shows best in a pendant or a pair of earrings, safe there from the knocks a ring collects, and the color keeps moving all day. Add a peridot piece as the steady counterpoint. Keep the opal out of salt, out of soaking and out of the sun, whatever a cleansing ritual tells you. The harmony and the hope people have seen in opal since Rome are tradition, and a good Libra gift honors the tradition and the care instructions at once.
The Text Behind Libra's Two Stones
These are page references, not paraphrase. Follow the link and the wording is right there.
- Chrysolite as Libra's stone in the older zodiac table
Kunz 1913, p.345-347, ZODIACAL GEMS
“Through Libra's sign it is quite well To free yourself from evil spell, For in her gem surcease doth dwell, The chrysolite.” - Kunz's Libra window running a day later on both ends
Kunz 1913, p.345-347, ZODIACAL GEMS
The table lists Libra as running “September 22 to October 23,” a day later on both ends than the September 23 to October 22 range used on modern astrology charts. - The separate monthly stone covering early Libra birthdays
Kunz 1913, p.345-347, ZODIACAL GEMS
The month table and the zodiac chapter were compiled independently in the same volume, so a Libra born before September 30 falls under sapphire on one list and opal on the other.
