Close to the heart
A round moonstone under a constellation of lab diamonds
A round moonstone of about 0.48 carats sits at the center of the Cancer constellation.
Cancer Star sets a round moonstone at the center of a constellation drawn for the Cancer sign, with lab diamonds placed around it as the stars. The moonstone holds a soft sheen that seems to glow from just beneath its surface and shifts gently as the light moves, so the pendant looks a little different from one moment to the next. It is a quiet piece that rewards a second look.
The moonstone weighs about 0.48 carats, a size that sits clearly at the neckline without crowding the chain. Each lab diamond is grown in a lab with the same chemistry as a mined diamond, so the constellation keeps a clear and steady sparkle from every angle. The stones sit close together, which makes the design read as one small, complete picture.
The design is close to the skin and feels personal rather than loud. It suits daily wear with simple knits, soft shirts and the everyday clothes you reach for most often, and it looks just as at home with a dressed-up outfit for dinner.
Gentle and easy
A necklace that stays close and comfortable
A 16 inch chain with a 2 inch extender and about 1.08 grams of metal.
The chain is 16 inches with a 2 inch extender, a comfortable length that sits at the collarbone. The extender lets you lower the constellation a little when you want more room for layering with other necklaces, or a softer line with a wider neckline.
The metal weighs about 1.08 grams, so the necklace feels light and moves gently when you walk or lean in to talk. Sterling silver gives the frame a cool, crisp finish, while yellow gold vermeil adds a warm tone that complements the moonstone's soft glow.
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 or emotional stretch. Cancer is linked with home, care and a deep sense of feeling, so this constellation suits anyone who values a quiet, nurturing rhythm. The meaning is yours to choose, and the necklace makes no promise of a particular result.
Some people give a Cancer necklace to a friend who looks after everyone else and rarely asks for anything in return. Others wear one as a private reminder to make room for their own rest, especially on a long week when the day keeps asking for more.
Choosing your sign
The constellation in this necklace is drawn for the Cancer 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 rest of your jewelry.
Measure a necklace you already wear and see where the pendant sits on your neckline. The extender gives you a little extra length, so you can try two positions and pick the one that feels most natural to 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 necklace looks the way it did on the first day.
Find your metal tone
Two finishes with the same Cancer constellation necklace. Pick sterling silver for a cool, clean line or yellow gold vermeil for warmth.

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.
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.
Which sign is this design for?
