    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 rainbow moonstone, grade AA, in round shape, set as part of the Capricorn 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.

    Yes. Solid gold is an alloy throughout, so the metal is not a plated or vermeil layer. The karat is shown on the product page.

    Clean lines, steady light

    A rainbow moonstone and six diamonds in a Capricorn constellation

    A rainbow moonstone and six conflict-free diamonds laid out as a Capricorn constellation, in 10kt solid white gold.

    Keystone lays a rainbow moonstone and six conflict-free diamonds out in the shape of the Capricorn constellation. The design is ordered and precise, and the moonstone's soft play of colour sits at the centre of the pattern.

    The diamonds set around the moonstone send small, even points of light across the white gold. The stones together make a tidy, balanced line that reads clearly from the front of the neckline.

    Keystone is made in 10kt solid white gold on a 16-inch chain with a 2-inch extender. It suits a professional occasion, a long working day or a weekend project, and it sits neatly beside a tailored jacket or a fine knit.

    The complete angular pendant rests on a pale gray surface with its two chain attachment loops visible.

    Solid white gold, close fit

    A solid white gold chain that stays in its place

    A 10kt solid white gold necklace with a constellation pendant, on a chain of 16 inches with a 2-inch extender.

    The necklace stays in its place through a full day. The constellation lies flat against the chest, and the solid white gold chain is steady enough that the pendant does not drift to one side.

    The chain is 16 inches with a 2-inch extender, so you can set the length for a high collar or a lower neckline. The white gold keeps the moonstone and the diamonds cool, clear and easy to pair with other silver and white metals.

    The meaning of renewal

    Moonstone is often associated with renewal, the sense of a fresh start that many people mark with a new piece of jewelry. Capricorn is traditionally linked with patience, discipline and steady effort over the long run, so a constellation of moonstone and diamonds suits anyone who starts again with a clear plan. The meaning is yours to choose, and the necklace makes no promise of a particular result.

    Some people give a Capricorn constellation necklace to mark a new year, a promotion or a fresh chapter in a long-term project. Others wear one as a quiet reminder that a steady beginning can carry them a long way.

    Choosing your sign

    The constellation is designed for the Capricorn sign. Check the product page to confirm that the design matches the sign you want to wear before you order.

    The necklace comes in one finish, 10kt solid white gold, so the choice is about the design and the chain length you prefer.

    Caring for the moonstone and diamonds

    Moonstone can scratch if it knocks against hard surfaces, and chlorine, lotion, perfume and heat can dull its sheen. Diamonds are very hard, but a sharp knock can still loosen a small stone. Remove the necklace before swimming, showering, exercise and sleep.

    After wear, wipe the necklace with a soft dry cloth and store it in a separate pouch. Keeping it apart from harder jewelry protects the moonstone, the diamonds and the white gold.
