    Representative material visualization · Appearance may vary

    Aquamarine is a natural material selected for its natural visual character. Surface, color and pattern can vary with the cut, finish and individual piece; the product photographs and measurements describe the item you will receive.

    In this piece: a pear-shaped brilliant aquamarine, about 9 by 6 millimeters, as the main stone.

    What does aquamarine symbolize?

    In crystal and jewelry traditions, aquamarine is associated with reflection, intention and personal style. These meanings are cultural and personal; they are not medical benefits or promises.

    Will every aquamarine piece look the same?

    No. Variation can come from the material, cut, finish and lighting. Use the individual product photographs and measurements to judge the piece you will receive.

    How should I care for it?

    Keep finished jewelry away from hard impacts, harsh chemicals and abrasive cleaners. Follow the product-specific care instructions, including those for metal finishes and other components.

    A lab-grown diamond is a crafted material with the same optical and physical properties as a mined diamond. Its brilliance and cut vary with the individual stone; the product photographs and measurements describe the item you will receive.

    In this piece: lab diamond embellishments set around the aquamarine.

    Is a lab diamond the same as a mined diamond?

    A lab-grown diamond has the same optical and physical properties as a mined diamond. It is grouped here as a crafted material because it is grown in a lab.

    Will every lab diamond piece look the same?

    No. Variation comes from the material, cut, finish and lighting. Use the individual product photographs and measurements to judge the piece you will receive.

    How should I care for it?

    • 925 silver
    • Silver alloy
    • Gentle care

    Representative material visualization · Appearance may vary

    Sterling silver is a silver alloy used in jewelry. Its bright, cool-toned surface can develop a natural patina with wear and exposure. The visible finish may also be plated, so always check the metal option for the individual piece.

    In this piece: 925 sterling silver, or 18kt gold vermeil over sterling silver, for the chain and the setting.

    Is sterling silver the same as a silver-colored finish?

    No. A silver-colored appearance alone does not establish metal content. Use the product's confirmed material specification; never identify sterling silver from its color or a reference photograph.

    Can sterling silver have a gold-colored finish?

    Yes. A gold layer can be applied over a sterling-silver base. In a vermeil option, the base metal and surface finish should both be stated; it must not be described as solid gold.

    How should I care for the finish?

    Store jewelry dry and separately, avoid cosmetics and household chemicals, and use a soft cloth. Follow the product's own care instructions before using silver cleaner, especially when stones, thread or gold plating are present.

    Crystal meanings are shared as traditional symbolism for personal reflection. They are not medical, financial, or professional advice, and they do not guarantee an outcome.

    Clear blue water

    A pear-cut aquamarine with lab diamond accents

    A pear-shaped brilliant aquamarine of about 1.47 carats, set with lab diamonds.

    Harbor holds a pear-shaped brilliant aquamarine of about 1.47 carats at the front of the pendant. The stone measures about 9 by 6 millimeters, and its clear blue tone looks like calm water under a bright sky, with the pointed tip of the pear leading the eye down.

    Lab diamond embellishments sit around the aquamarine and add sharp points of light beside its soft blue. Each lab diamond is grown in a lab with the same chemistry as a mined diamond, so the setting sparkles without drawing focus from the stone at the center.

    Aquamarine is the March birthstone, which makes Harbor a meaningful gift for a March birthday. The cool, clean color suits light blue shirts, white knits and the relaxed outfits of a warm-weather day.

    Light and steady

    A necklace that rests lightly at the collarbone

    A 16 inch chain with a 2 inch extender and about 2.53 grams of metal.

    The chain is 16 inches with a 2 inch extender, a length that sits at the collarbone and frames the blue stone well. The extender lets you lower the pendant for a looser line or raise it for a close, neat look.

    The metal weighs about 2.53 grams, a steady weight that feels comfortable through a full day. Yellow gold vermeil adds a warm frame that sets the blue off beautifully, while sterling silver keeps the look cool and clear.

    The meaning of courage

    Aquamarine is often associated with courage and serenity, the quiet confidence that lets a person move forward with a calm mind. Its clear blue has long been linked with steadiness and with facing a new stretch of the road without hurry, so Harbor suits anyone who likes to take a brave step while keeping their composure. The meaning is yours to choose, and the necklace makes no promise of a particular result.

    Some people give an aquamarine necklace to mark a March birthday or to a friend who is starting something new. Others wear one for its cool, sea-like color and the sense of calm it brings to a busy day.

    Choosing your finish

    Yellow gold vermeil adds a warm frame that makes the blue look especially rich, while sterling silver keeps the aquamarine crisp and cool against light clothing.

    Measure a necklace you already wear and check where the pendant falls on your neckline. The extender gives you a little more length, so you can try two positions and choose the one that flatters you most.

    Caring for the aquamarine and finish

    Aquamarine can be scratched by harder stones, and salt water, chlorine, heat and lotion can dull both the stone and the vermeil. Remove the necklace before swimming, showering, exercise and sleep, and keep it away from hot surfaces and sprays.

    After wear, wipe the piece with a soft dry cloth and store it in a separate pouch. Keeping it apart from other jewelry protects the aquamarine, the lab diamonds and the finish, so the blue keeps its clear, calm tone.

    Find your metal tone

    Two finishes with the same aquamarine necklace. Choose sterling silver for a cool, sea-bright line or yellow gold vermeil for warmth.

    Frequently asked questions

    Is the aquamarine natural?

    Yes. Aquamarine is a natural gemstone, and its blue tone varies from one stone to another.

    Are the lab diamonds natural?

    Is this necklace in stock now?

    The necklace is sold as a standard item. Check the product page for the delivery estimate shown there before you order.

    Can I adjust the length?

    Yes. The chain is 16 inches with a 2 inch extender, so the pendant can sit a little lower when you want more room.

    Are the finishes solid gold?

    No. The gold finish is 18kt yellow gold vermeil over sterling silver, a thin gold layer rather than solid gold.

    Does the necklace promise any effect?

    No. Aquamarine is often associated with courage and serenity, and those meanings are yours to choose. The necklace makes no promise of a particular outcome.

    Can I wear it in the shower or pool?

    How should I clean it?

    Wipe gently with a soft dry cloth. Avoid harsh polishes and ultrasonic cleaners, which can damage the aquamarine and the finish.

    Why is it a birthstone necklace?
