June Birthstones: Pearl, Alexandrite and Moonstone Guide
The June birthstones are pearl, alexandrite and moonstone. They offer three very different looks: pearl luster, alexandrite’s change of color and moonstone’s moving sheen. Choosing between them is easier when you compare appearance, identity and the care each gem needs.

Pearl: a June birthstone made by a mollusk
Pearls form in mollusks rather than growing as mineral crystals in rock. Both natural and cultured pearls are real pearls. Cultured pearls form with human involvement; they are not the same thing as imitation pearl beads.
White pearls are familiar, but pearl colors and shapes vary. For a gift, look at the brightness and clarity of the reflected light, the surface condition and how well the pearls match in a pair or strand. Ask whether the color is natural or treated. A neat-looking string of beads is not enough to establish that they are pearls.
Alexandrite: the color-change June birthstone
Alexandrite is a variety of chrysoberyl. Its color change depends on the lighting: fine examples can appear greenish in daylight and reddish or purplish under incandescent light. Not every example has an equally strong change.
Ask for a demonstration under two clearly identified light sources. A single photograph does not show the whole effect. Laboratory-grown alexandrite also exists. The trade phrase “alexandrite sapphire” can describe color-change sapphire, which is a different material. Ask for the actual gem identity instead of relying on that name.
Moonstone: a soft-looking glow
Moonstone is a feldspar gem. Its sheen, called adularescence, comes from the way light interacts with tiny internal layers. Turn the stone slowly to see how that sheen moves. The lighting, viewing direction and background all matter when comparing photographs.
Moonstone is associated with the Moon and with love in different traditions. These are cultural associations, not scientific evidence of healing, fertility benefits or luck. A gift can be meaningful simply because its appearance reminds the recipient of moonlight.
Which June birthstone is right for a gift?
Choose the gem for the wearer’s habits as well as its look. Alexandrite has good resistance to wear and is a practical ring candidate. Pearl and moonstone need more protection. Earrings and pendants may suit someone who wants their appearance without exposing a stone to frequent knocks on the hand.
Ask for clear photographs, dimensions, treatment disclosure and natural or laboratory-grown status where relevant. For pearls, ask whether they are natural or cultured. For an important purchase, consider an independent identification report. There is no need to select all three June birthstones; one well-chosen piece can carry the birthday connection.
Care depends on the gem
- Pearl: wipe gently after wear with a very soft cloth. Put jewelry on after perfume and cosmetics. Keep it away from acids, heat and rough contact. Never use an ultrasonic or steam cleaner.
- Moonstone: avoid sharp blows, high heat and sudden temperature changes. Use mild soapy water and a soft brush, never steam or ultrasound.
- Alexandrite: mild soapy water is a cautious routine choice. Have a professional check fractures, treatments and the setting before using a stronger cleaning method.
June birthstone questions
Are cultured pearls fake?
No. They are real pearls grown with human intervention. Imitation pearls are different materials.
Does hardness mean a stone will not break?
No. Hardness measures resistance to scratching. Toughness and the condition of the particular gem also matter.
