June Birthstone Guide: Pearl, Moonstone, & Alexandrite

June 1, 2026

June's birthstone isn't just one gem — it's three. Pearl, moonstone, and alexandrite are all official June birthstones, each with a distinct origin, appearance, and meaning.

Whether you're shopping for yourself, looking for a gift, or simply curious, this guide covers everything from history and symbolism to styling and how to choose the right one.

What Are June’s Birthstones?

PEARL

Pearl is the traditional June birthstone and one of the most well-known gemstones in the world, formed by living organisms rather than being mined from the earth.

Pearls grow inside oysters and mollusks when an irritant enters the shell, causing the creature to coat it in layers of nacre, a lustrous substance that eventually forms the pearl we know and love.

This organic origin gives pearls their distinct soft luster and gentle, creamy glow — a quality no synthetic stone can replicate. High-quality pearls have a reflective, almost mirror-like surface that makes them appear luminous from the inside.

Their understated elegance has been treasured across cultures and centuries.They remain as relevant today as ever.

MOONSTONE

The light moves inside a moonstone rather than reflecting off it, resulting an a phenomenon called adularescence, a soft, billowing glow that appears to float beneath the surface when illuminated. The effect is called adularescence, and in the finest stones it appears as a blue sheen against a near-colourless background.

Moonstone is the best-known gemstone of the feldspar group of minerals, and it has long been associated with Roman and Greek lunar deities. Its name is derived from this connection: the Roman natural historian Pliny the Elder observed that the stone's shimmery appearance appeared to change with the phases of the moon.

Today, moonstone is popular in ethereal, spiritual, and minimalist designs. It has a romantic, otherworldly quality that suits those who want their jewelry to carry meaning as well as beauty.

ALEXANDRITE

Few gemstones command attention the way alexandrite does.In daylight or fluorescent light, alexandrite appears green to bluish-green; under incandescent or warm candlelight, it shifts to purplish-red. This phenomenon is commonly referred to as "emerald by day, ruby by night."

The colour shift is caused by traces of chromium in alexandrite's chemical composition — the same element that gives emeralds their green.

First discovered in Russia in the 1830s, alexandrite is among the rarest gemstones in the world. Its beauty, rarity, and remarkable transformation have made it a defining stone for collectors and connoisseurs.

What Colour are June’s Birthstones?

Pearl: White to cream, with soft iridescent overtones that shift between pink, gold, and silver depending on the light. No two pearls catch colour in quite the same way.

Moonstone: A translucent base with an inner blue to white glow — cool, quiet, and luminous. Some stones lean peach or grey, but the inner light is always the defining feature.

Alexandrite: Green to teal in daylight; red to purplish-red under incandescent light. The same stone looks entirely different depending on where you wear it, which is precisely what makes it extraordinary.

Why Does June Have Three Birthstones?

The tradition of birthstones is traced back to biblical descriptions of priestly garments adorned with twelve stones representing the twelve tribes of Israel, an origin that eventually became linked to the twelve months of the year.

The modern birthstone list was first standardized in 1912 by the National Association of Jewelers of America, and has been refined several times since.

The practical reason for multiple birthstones is accessibility, giving people more options across price points, color preferences, and aesthetic styles. For June specifically, each birthstone serves a different kind of wearer. Pearl became associated with the month through long-standing tradition and timeless elegance. Moonstone gained recognition for its dreamy, ethereal appearance and soft spiritual associations. Alexandrite was added as the more luxurious option - a collector's birthstone for those who want something genuinely rare.

The Meaning & Symbolism of June Birthstones

PEARL MEANING

Pearls have long been associated with purity, humility, and innocence — which is also why they have been given as wedding gifts for centuries.More than bridal tradition symbolism, there is a quiet confidence to pearls. Pearls suggest wisdom and emotional steadiness — refinement that feels earned rather than performed.

Pearls appeal to those who value quality over trend, and understand that the most enduring things rarely shout.

MOONSTONE MEANING

Moonstone's symbolism is rooted in its appearance. The soft inner glow that appears to emanate from somewhere beyond the surface. It is a stone associated with intuition, new beginnings, and the kind of inner growth that happens quietly and over time.

For those drawn to softer, more contemplative aesthetics — people who wear jewelry that feels like it means something — moonstone fits naturally. It is not a stone that performs. It is a stone that resonates.

ALEXANDRITE MEANING

Because of its ability to transform under different lighting conditions, alexandrite has become associated with duality, adaptability, and change. It is rare and refined, with an edge that keeps it interesting.

Alexandrite suits those who value individuality in their jewelry — who wants to wear something that says something about them without having to explain it.
