Care & cleaning
Your Irosk piece is crafted to last with simple care.
Daily wear: Avoid contact with perfume, hairspray, lotions and chlorinated water. Apply your beauty products before putting on your jewellery, never after.
Cleaning: Gently polish with a soft lint-free cloth. For a deeper clean, use warm water with a drop of mild soap, pat dry with a soft cloth, and air-dry fully before storing.
Storing: Keep each piece in its own pouch or compartment to prevent scratching. Store in a cool, dry place away from direct sunlight.

Real silver, not cheap plating
Built to outlast the trend cycle
Our jewellery is crafted from 925 sterling silver — the international standard for fine silver. Every piece is then plated with rhodium, a precious metal from the platinum family that gives a brilliant white finish and a tarnish-resistant shield around the silver beneath.
Why this matters
Most "silver" jewellery you'll see online uses thin plating over base metal. It tarnishes within weeks, irritates sensitive skin and ends up in a drawer. Our rhodium-plated 925 silver stays bright for years with simple care, doesn't trigger nickel allergies and feels heavier in the hand — because it's the real thing.
Backed for a year, made for a lifetime
We stand behind every piece with a 365-day warranty against tarnish, plating wear and manufacturing defects. If your iROSK piece dulls within a year of purchase under normal wear, we'll re-plate or replace it free.
