About Emerald

Emerald is a green variety of beryl, coloured by trace amounts of chromium and sometimes vanadium. It belongs to the same mineral family as Aquamarine. The finest emeralds come from Colombia (Muzo and Chivor mines), Zambia, and Brazil. Colombian emeralds are considered the world standard for quality.

Unlike diamonds, emeralds are almost always included – internal fractures called "jardin" (French for garden) are considered part of the stone's character. An emerald with no inclusions would be extraordinarily rare and suspicious – likely synthetic.

Emerald Meaning & Symbolism

Emerald is the stone of the heart chakra – unconditional love, compassion, partnership, and healing. It is associated with Venus and the energy of spring: renewal, growth, and abundance in all its forms. Ancient Egyptians believed emeralds represented fertility and rebirth and buried them with their dead.

Cleopatra was famously obsessed with emeralds and claimed ownership of all emerald mines in Egypt. She gifted large emeralds, engraved with her likeness, to foreign dignitaries. The Incas and Aztecs worshipped emeralds as sacred stones long before the Spanish conquest.

Healing Properties

Emotional

Emerald opens the heart, promotes unity, compassion, and unconditional love. It eliminates negativity and brings in positive actions. It enhances loyalty and provides for domestic bliss, sensitivity, and loyalty in relationships.

Spiritual

Emerald stimulates the heart chakra, connecting the physical and spiritual realms. It is said to inspire a deep inner knowing, wisdom, and discernment – helping the wearer distinguish between real and illusory visions.

History & Lore

The oldest known emerald mines date back to at least 1,500 BC in Egypt. The Romans dedicated the emerald to Venus. In medieval Europe, emerald was believed to reveal whether a lover's oath was true – it was said to shatter if a promise was broken. The Spanish Crown Jewels contain spectacular Colombian emeralds looted during the conquest of South America.

How to Wear and Use Emerald

Emerald is beautiful and demanding. At 7.5 to 8 it sounds durable, but nearly every natural emerald is threaded with internal fractures — the trade calls them the jardin, the garden. They make the stone more brittle than the number suggests, and an emerald lives a harder life in an everyday ring than a sapphire or a diamond would.

The sensible compromise is earrings or a pendant, where the stone takes no knocks, and a ring kept for occasions. Symbolically emerald is tied to the heart, honesty and memory, which is why it so often becomes a family stone.

May Zodiac Signs and Their Stones

Taurus until 20 May, Gemini from the 21st. Emerald is traditionally the Taurus stone and this is one of the more durable correspondences — both are associated with loyalty, steadiness and a fondness for what is beautiful and tangible.

Gemini is more often given agate and citrine, which are livelier. If May's emerald feels heavy in character, that is the usual Gemini reaction to it.

How to Cleanse and Charge Emerald

This is the section that matters most on the page. The overwhelming majority of emeralds on the market are oil- or resin-filled, a legitimate and completely standard treatment that fills the fractures and improves the look of the stone. It also changes the care rules entirely: hot water, ultrasonic and steam cleaners wash the filler out, and the stone clouds while you watch, permanently.

Wipe emerald with a soft damp cloth and dry it at once. No salt, no washing-up liquid, no ultrasonic. Charge it by moonlight or sound.

How to Spot a Fake Emerald

The paradox of emerald is that clarity is a warning sign. Natural stone is almost always included, so a perfectly transparent, vividly green emerald at a low price is either glass or hydrothermal synthetic.

Glass shows round bubbles and sometimes swirl marks under a loupe. Synthetic emerald is harder and really needs a gemmologist. Doublets also circulate — a thin slice of emerald glued to a cheaper base — and they give themselves away with a glue line visible from the side.

Questions People Ask

What is the birthstone for May?

Emerald, the green variety of beryl. It is also the traditional Taurus stone, one of the more consistent overlaps between the monthly and zodiac lists.

Can emerald go in water?

Only briefly and only cool. Almost all emeralds are oil- or resin-filled, and hot water, steam and ultrasonic cleaners wash the filler out, clouding the stone permanently.

Why does my emerald have cracks in it?

That is the jardin, the natural network of inclusions found in nearly every emerald. It is not a flaw but a sign of authenticity — a flawless cheap emerald is usually glass or synthetic.

Is emerald suitable for an everyday ring?

Not really. Those internal fractures make it more fragile than its hardness of 7.5 to 8 suggests. Earrings or a pendant are the safer setting.
