✨ Why You'll Love It
✔ Classic Prong-Set Crystal: A brilliant 3mm round cubic zirconia is held within a clean prong setting, creating a timeless focal point with bright, light-catching sparkle.
✔ ASTM F136 Titanium: Lightweight, durable and highly resistant to corrosion, titanium is an excellent choice for customers concerned about nickel sensitivity.

💎 The Detail
Simple, sparkling and endlessly easy to style, this Titanium Prong Set Crystal Stud is a versatile addition to almost any curated ear stack. The minimal setting keeps the round crystal at the centre of the design, giving it plenty of brilliance while maintaining a clean, understated silhouette.
Available in silver or gold with a 16 Gauge, 8mm internally threaded flat-back post, it can be styled in compatible helix, flat, forward helix, tragus, conch and lobe piercings. The correct post length and jewellery style will depend on your individual anatomy and piercing placement.
Stainless steel piercing forceps help grip jewellery securely when opening hoops or unscrewing tight posts or ball ends.

CARE & LONGEVITY
A little thoughtful care will help your jewellery look its best for longer.
This piece has a PVD finish. Avoid prolonged exposure to water, perfume, lotions and other chemicals to help preserve its appearance.
Put your jewellery on after applying perfume, moisturiser, hairspray or other beauty products. Avoid unnecessary friction and prolonged exposure to moisture.
Chlorine, seawater, sweat, perfume and household chemicals can gradually affect coated or plated finishes. Remove your jewellery before swimming and dry it promptly if it becomes wet.
Clean carefully with a soft cloth. If a deeper clean is needed, use a lightly dampened cloth and dry thoroughly. Avoid polishing compounds, abrasive products and harsh chemical cleaners.
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.
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.
