✨ Why You'll Love It
✔ Sparkling Crescent Moon Design: A delicate 6mm crescent moon is filled with tiny cubic zirconia, creating a celestial statement with beautiful detail and sparkle.
✔ Detailed Mixed-Material Design: A durable 316L surgical steel post is paired with a decorative brass moon topper, allowing for the more intricate crystal-set design.
✔ Internally Threaded Flat Back: The threading sits inside the post for a smooth exterior, while the flat-back design creates a clean, streamlined finish when worn.
💎 The Detail
Celestial, sparkling and easy to build into an ear stack, this Crystal Moon Stud gives the classic crescent motif a more decorative finish with a surface of tiny light-catching stones. The compact 6mm topper makes a distinctive focal point while remaining easy to pair with simple hoops, stars and other crystal jewellery.
Available in silver, rose gold or gold with a choice of 6mm or 8mm internally threaded flat-back posts, it can be styled in compatible helix, flat, forward helix, tragus, conch, lobe and labret piercings. The correct post length and jewellery style will depend on your individual anatomy and piercing placement.

CARE & LONGEVITY
A little thoughtful care will help your jewellery look its best for longer.
This design contains brass and should be kept dry and worn only in fully healed piercings. Remove before showering, swimming, exercising or sleeping.
Jewellery containing brass is best reserved for occasional wear. Remove it before showering, swimming, exercising or sleeping to help protect the decorative finish.
Brass can react to water, sweat, perfume and lotions. Keep this piece dry and avoid contact with swimming pools, seawater, cleaning products and cosmetics.
Wipe gently with a soft, dry microfibre cloth. If necessary, use a very lightly dampened cloth and dry immediately. Avoid soaking, abrasive cleaners and jewellery-polishing chemicals.
Avoid bleach, alcohol, abrasive cleaners and other harsh chemicals.
Store your jewellery somewhere clean and dry, ideally separately from other pieces to prevent scratches or tangling. The pouch provided with your order is perfect for keeping it protected.
Avoid knocking, pulling or catching crystal settings on clothing. Clean around decorative details gently and avoid soaking or using abrasive brushes.
Apply perfume, moisturiser and hairspray before putting on your jewellery. Avoid abrasive cloths, polishing treatments and prolonged exposure to chlorine or seawater.
Although this piece may have a durable metal bar, its brass detailing needs extra care. Always follow the guidance for the most delicate material and keep the entire piece dry.
Jewellery care is different from piercing aftercare. If your piercing is new, irritated or still healing, speak to a professional piercer before changing your jewellery.
