    Moonstone

    Moonstone
    • Shifting glow
    • Natural variation

    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.

    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.

    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
    • 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.

    Sagittarius Star moonstone and lab diamond necklace

    Open horizon

    A moonstone among a constellation of lab diamonds

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

    Sagittarius Star centers a round moonstone of about 0.64 carats in a constellation drawn for the Sagittarius sign. The lab diamonds are spread outward from the stone, as if pointing toward a wide sky, and the moonstone's sheen keeps the design soft and luminous rather than sharp.

    Each lab diamond is grown in a lab with the same chemistry as a mined diamond. The constellation uses open spacing, so the stones catch the light from different angles as you move, and the pendant seems to shift a little with each step you take.

    The design feels adventurous without being loud. It works with travel clothes, denim, linen and bright tops, and it looks at home in a sunny outdoor setting as easily as at an evening table.

    Light and ready to move

    A necklace that goes wherever the day takes you

    A 16 inch chain with a 2 inch extender and about 1.78 grams of metal.

    The chain is 16 inches with a 2 inch extender, a comfortable length that sits at the collarbone. The extender offers a longer line when you want the pendant to fall lower, which suits layering with a second necklace on a busy day out.

    The metal weighs about 1.78 grams, so the pendant feels easy to wear through a full day of walking. Yellow gold vermeil adds a sunny warmth, while sterling silver keeps the look cool and simple for everyday outfits.

    Choosing your sign

    The constellation in this necklace is drawn for the Sagittarius 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 your everyday style.

    Measure a necklace you already wear and see how far the pendant falls on your neckline. The extender gives you a little more length, so you can wear it higher for a neat look or lower for a relaxed one.

    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, especially on warm, sunny days when sunscreen and sea water are close by.

    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 stays bright for the next adventure.

    Find your metal tone

    Two finishes with the same Sagittarius constellation necklace. Choose yellow gold vermeil for warmth or sterling silver for a light, modern 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 for travel layers or a relaxed look.

    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.

    Can I wear it in the shower or pool?

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

    How should I clean it?

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