Pictured: Colorful Gemstone Delight Ring

The March birthstone is Aquamarine, a pale blue stone associated with courage, calm, and safe passage over water. It rates 7.5 to 8 on the Mohs hardness scale, which is the number that actually decides whether you can wear it every day.

What Aquamarine means

Aquamarine has long been linked to courage, calm, and safe passage over water. Aquamarine is a beryl, the same family as emerald but far tougher, and its pale blue reads well against both gold and silver.

Buying March birthstone jewelry at Costco and other warehouse clubs

Costco does sell genuine fine jewelry, including birthstone pieces, and its pricing is usually competitive because margins are thin and volume is high. Diamonds are commonly certified, and the return policy is unusually generous. Those are real advantages if you are buying a significant piece.

The trade-offs are equally real. Selection is limited and rotates with stock rather than being a permanent catalogue, so a specific Aquamarine piece may or may not be there when you look, and a membership is required. Timing matters too: March sits between Valentine's Day and Mother's Day, one of the better windows for both selection and price.

What actually matters for a piece you wear daily

At 7.5 to 8 on the Mohs scale, Aquamarine is hard enough to survive daily wear, including in a ring where knocks are frequent. Soapy water is fine. Avoid heat, which can alter colour.

The other half of the equation is the metal. A genuine stone set into plated brass will outlive its setting: the plating wears, the base reacts with skin, and you end up with a good stone in a piece you have stopped wearing. Whatever stone you choose, the setting decides how long you actually wear it.

The everyday alternative

If what you want is the colour and the meaning rather than the carat weight, look for pale blue aquamarine-toned stones set on a non reactive base. Same look, none of the fragility or the price. This is the entire premise behind Ezra Gems: waterproof, hypoallergenic jewelry on a surgical-grade stainless steel core, made to be worn daily and never babied. Nothing needs removing before a shower, and nothing tarnishes underneath.

The Short Version

March is Aquamarine: pale blue, 7.5 to 8 on the Mohs scale, and linked to courage, calm, and safe passage over water. Buy the stone for the meaning, but judge the setting on whether it will survive being worn. Shop Birthstone Jewelry.

Frequently Asked Questions

What is the March birthstone?

The March birthstone is Aquamarine.

Can you wear Aquamarine every day?

It depends on hardness. Check the Mohs rating in the table above: stones at 7.5 and higher handle daily rings well, softer stones are better in earrings or pendants where they take fewer knocks.

Is Costco a good place to buy birthstone jewelry?

Costco sells genuine fine jewelry at competitive prices with a generous return policy, which suits milestone purchases. Selection is limited and rotates, and a membership is required, so it is less useful for a specific piece you want on demand.

Is Ezra Gems jewelry really waterproof?

Yes. Every piece is 18K gold plated over surgical stainless steel, a non reactive base that does not corrode in water, chlorine, or salt. You can shower, swim, sweat, and sleep in it.

Will it turn my skin green?

No. There is no copper or brass touching your skin, only surgical stainless steel under the gold plating, so it will not leave green marks or discoloration.

Is it hypoallergenic and nickel free?

Yes. Every piece is nickel free and free of lead and cadmium, made for sensitive skin and ears that react to ordinary gold tone jewelry.
