Sensitive Skin

Zostma — designed for everyone
Fine jewellery for sensitive skin
Jewellery should never be something you have to give up. Every Zostma piece is crafted with material choices that put your skin first.
Our metals
Two metals. Chosen with your skin in mind.
Among the metals we work with, two stand out for sensitive skin — and we want you to know exactly why.
Best for sensitive skin
14k Gold Filled
The gold standard
A thick, pressure-bonded layer of solid 14k gold — approximately 100x thicker than gold plating. The gold acts as a complete barrier between your skin and the base metal beneath.
  • Safe for virtually all skin types
  • Ideal for most nickel sensitivities
  • Our top recommendation for sensitive ears
  • Durable — the gold layer does not wear off easily
Rhodium Plated 925 Silver
Hypoallergenic by nature
925 sterling silver with a rhodium finish. Rhodium is one of the most hypoallergenic metals available — it sits as a protective, skin-safe layer over the silver beneath.
  • Rhodium is naturally hypoallergenic
  • Well tolerated by the vast majority of sensitive skin types
  • Protective barrier that keeps skin away from the silver
  • Bright, tarnish-resistant finish
Not sure which to choose? If you have a known nickel allergy or have reacted to jewellery before, our 14k gold filled pieces are your safest option. For generally sensitive skin, both metals are excellent choices.
Our stones
Both stones. Completely hypoallergenic.
Moissanite and cubic zirconia are both lab-created, hypoallergenic stones — free from allergens and safe for all skin types. Another reason they are such a considered choice for everyday jewellery.
Moissanite
A lab-created silicon carbide gemstone with no metallic components. Cannot cause an allergic reaction. Safe for all skin types without exception.
Cubic Zirconia
A synthesised zirconium dioxide — inert, hypoallergenic and well tolerated by all skin types. Used safely in jewellery for decades.
Why it matters
Many jewellery reactions come from the metal setting, not the stone. With hypoallergenic stones in hypoallergenic settings, every element is considered.
