Available in a range of opal colours and metal finishes, this 16 Gauge Internally Threaded Iridescent Opal Top Stud is crafted from durable 316L surgical steel with a choice of 6mm or 8mm posts. The smooth lab-created opal topper reflects shifting tones as it catches the light, creating a colourful, luminous finish that's easy to style within almost any ear stack.
✨ Why You'll Love It
✔ Iridescent Opal Finish: The smooth lab-created opal reflects beautiful shifting tones in the light, creating a colourful focal point with a soft, luminous glow.
✔ Durable 316L Surgical Steel: Crafted from strong 316L surgical steel for a practical, low-maintenance jewellery choice designed for healed piercings.
✔ 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
Simple in shape but full of colour, this Iridescent Opal Stud is an easy way to add something different to a curated ear stack. The smooth round opal has a luminous, colour-shifting appearance that changes with the light, while its clean setting keeps the overall design refined and easy to combine with both crystal and polished metal jewellery.
Available in a range of colours and finishes with a choice of 6mm or 8mm internally threaded posts, 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.

uses for healed piercings and are not a guarantee of fit. Always consider the
jewellery design, your piercing placement and your individual anatomy. New or
healing piercings should be sized by a professional piercer.
