    Natural stones

    Moonstone

    Moonstone
    • Shifting glow
    • Natural variation
    • Personal meaning

    Representative material visualization · Appearance may vary

    Moonstone is known for a soft glow that seems to move as the viewing angle changes. Color, translucency and the strength of this light effect vary from stone to stone, giving each piece its own character.

    In this piece: a round moonstone, about 0.60 ct, at the center of the constellation.

    Why does its glow change?

    Light interacting with layers within feldspar can create a floating sheen. Its visibility depends on the stone, the light and the viewing angle; a strong blue flash is not guaranteed in every piece.

    What does moonstone symbolize?

    Moonstone is traditionally associated with intuition, reflection and new beginnings. These are cultural meanings and personal reminders, not medical benefits or promises of a particular outcome.

    How should it be cared for?

    Protect it from hard knocks, abrupt heat changes, steam and ultrasonic cleaning. Follow the finished piece's care instructions too: thread, coatings and other components can require gentler care than a loose gemstone.

    Lab Diamond

    Lab Diamond
    • Lab Diamond texture
    • Lab Diamond tone
    • Personal meaning

    Representative material visualization · Appearance may vary

    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 diamonds set in the constellation design as its stars.

    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?

    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.

    Sterling Silver

    Sterling Silver
    • 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 constellation frame.

    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.

    Poised and even

    A moonstone set evenly within a constellation of lab diamonds

    A round moonstone of about 0.60 carats at the center of a Libra constellation.

    Libra Star sets a round moonstone of about 0.60 carats at the center of a constellation drawn for the Libra sign. The lab diamonds are placed with an even rhythm around the stone, so the design looks composed from the front and holds its shape as you turn.

    Each lab diamond is grown in a lab with the same chemistry as a mined diamond. The moonstone's sheen rises softly in the middle of the pattern, and the lab diamonds catch the light on either side, giving the pendant a calm and considered look.

    The style suits meetings, dinners and days when you want a piece that looks thoughtful without being fussy. It pairs well with tailored collars, soft knits and the neutral palette that most wardrobes already hold.

    Neat and graceful

    A necklace that lies neatly at the neckline

    A 16 inch chain with a 2 inch extender and about 1.56 grams of metal.

    The chain is 16 inches with a 2 inch extender, a length that sits neatly at the collarbone and suits collared shirts and open necklines alike. The extender lets you lower the constellation for a softer line when the occasion allows.

    The metal weighs about 1.56 grams, which gives the pendant a settled feel without any heaviness. Sterling silver keeps the frame clean and bright, while yellow gold vermeil adds a warm, polished tone that sits well with gold accessories.

    The meaning of calm

    Moonstone is often described as a stone of calm, a gentle and steady presence that many people reach for when a day feels full. Libra is linked with harmony, fairness and the art of keeping good relationships in step, so this constellation suits anyone who values a peaceful and considered way of being together. The meaning is yours to choose, and the necklace makes no promise of a particular result.

    Some people give a Libra necklace to a friend who is a natural mediator and a good listener. Others wear one as a quiet reminder to take a breath before deciding how to respond.

    Choosing your sign

    The constellation in this necklace is drawn for the Libra sign. Check the product page to confirm that the design matches the sign you want to wear before you order, and choose the finish that suits the other jewelry you wear.

    Measure a necklace you already wear and see where the pendant sits on your neckline. The extender gives you a little more room, so you can try two positions and see which one looks more balanced on you.

    Caring for the moonstone and diamonds

    Moonstone can scratch if it knocks against hard surfaces, and it dulls with heat, lotion and perfume. Remove the necklace before swimming, showering, exercise and sleep, and avoid storing it with harder pieces that could mark the stone.

    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 moonstone, the lab diamonds and the finish, so the constellation keeps its clean, even pattern.

    Find your metal tone

    Frequently asked questions

    Is the moonstone natural?

    Yes. Moonstone is a natural gemstone, and its soft sheen varies from one stone to another.

    Are the lab diamonds natural?

    No. Lab diamonds are grown in a lab rather than mined. They share the chemistry of mined diamonds.

    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 constellation can sit a little lower when you want it to.

    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.
