    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 0.64 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 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.

    Warm and open

    A moonstone at the heart of a bright constellation

    A round moonstone of about 0.64 carats set among lab diamonds in a Leo constellation.

    Leo Star centers a round moonstone of about 0.64 carats in a constellation of lab diamonds. The moonstone's sheen rises softly from within, while the lab diamonds catch sharper points of light around it. Together they create a pendant that looks warm in daylight and gleams gently under soft evening light.

    Each lab diamond is grown in a lab and carries the same chemistry as a mined diamond. The constellation is laid out so the stones read clearly from across a room, while the moonstone stays the calm centre of the design.

    Under warm light the moonstone takes on a soft, golden tone, and the constellation keeps its shine in both daylight and evening light.

    Easy confidence

    A necklace that sits well at the collarbone

    A 16 inch chain with a 2 inch extender and about 1.74 grams of metal.

    The chain is 16 inches with a 2 inch extender, a length that sits at the collarbone and suits both open necklines and high collars. The extender lets you drop the constellation a little lower when you want a longer line.

    Yellow gold vermeil gives the frame a warm, golden tone that works beautifully with a bright lipstick or a rich knit. Sterling silver keeps the look cool and clean for daytime outfits and tailored evening wear.

    The meaning of calm

    Moonstone is often described as a stone of calm, a soft and steady presence that many people turn to during a busy stretch. Leo is linked with warmth, generosity and a bright presence, and this constellation is a quiet reminder that a calm centre can sit at the heart of a bold look. The meaning is yours to choose, and the necklace makes no promise of a particular result.

    Some people give a Leo necklace to a friend who shines in a crowd. Others wear one simply because the moonstone's soft glow suits the way they like to present themselves.

    Choosing your sign

    The constellation in this necklace is drawn for the Leo sign. Check the product page to confirm the design matches the sign you want to wear before you order.

    Measure a necklace you already wear and check where the pendant sits. The extender gives you room to lower the constellation for layering with other pieces.

    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.

    After wear, wipe the piece with a soft dry cloth and store it in a separate pouch. Keeping it apart from harder jewelry protects the stone and the finish.

    Find your metal tone

    Two finishes with the same Leo constellation necklace. Choose yellow gold vermeil for a warm glow or sterling silver for a crisp, cool line.

    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.

    Does the necklace promise any effect?

    No. Moonstone is often described as a stone of calm, and that meaning is yours to choose. The necklace makes no promise of a particular outcome.

    Please remove it before swimming, showering or exercise. Water, lotion and chlorine can dull the moonstone and the finish.
