Our luxurious brand aesthetic is reflected through the high-quality materials used in our products - sourced from premium manufacturers in Europe, where the workmanship is second to none; stainless steel or brass base- having the highest-grade micron plating of 24K gold & 999 silver with an added Premium double E-coating finish to maintain the lustre of each piece for many seasons to come.

All items are Hypo-allergenic - Nickel, Lead and Cadmium Free, in accordance with EU REACH Regulations. 

Other materials used in our designs are premium Austrian crystals, Swarovski® Crystals, Freshwater Pearls, Myuki® Rocaille seed beads and semi-precious stones.

The earring posts are Titanium - which is extremely lightweight and ideal for people with concerns about nickel sensitivity, it is the most bio compatible element (less than 0.6% of people are allergic to it) and will not irritate even the most sensitive skin.  Since titanium is inert and non-reactive to almost all chemicals it will never corrode tarnish or rust.


Gold and silver plating is a method of bonding a thin layer of liquid gold or silver onto the surface of another metal such as brass or stainless steel by electrochemical plating. KATERINA ROZA pieces have one of the highest quality platings on our jewellery pieces.  Wear in plating is subject to change due to the acidity of the wearers skin, and exposure to products such as perfumes, moisturisers, tanning lotions or cleaning products. Wear in plating and tarnish are not manufacturing faults.

The length of time that plating will last varies to each individual. If you have not worn a plated item before we recommend researching this prior to purchasing.

Our beaded necklaces and bracelets are hand-beaded on industrial strength beading wire in our Sydney Studio. If you are experiencing any problems with our hand-crafted beaded items, please reach out to our care team here.

To clean your semi-precious stones, gently wipe with a damp cloth. Natural products such as semi-precious stones will take on moisture from their environment, so please avoid wearing them in water or exposing them to detergents or chemicals. Hair spray, perfumes, chemicals and soaps can damage and discolour the stones. Natural stones are subject to change over time through wear. 

Tarnish occurs for many reasons and is subject to the environment of the wearer. Tarnish is not a manufacturing fault as it can be caused by many different things such as perfumes, moisturisers, tanning lotions and cleaning chemicals. Even ones' skin acidity can cause metals to tarnish. Tarnish can also be a result of oxidation from the way items are stored. Oxidation is a natural process that occurs from the combination of oxygen with a substance forming oxide. This can be caused by either lack of oxygen or too much oxygen exposure. We recommend storing your pieces in a purpose-made jewellery box. We find that a simple polish with a clean microfibre or jewellery polishing cloth will remove tarnish. 

All of our pieces are Hyper allergenic - Nickel, Lead and Cadmium free! Please note that Katerina Roza is not liable to compensate customers for any reactions that are caused by our jewellery. If you experience any reactions to our jewellery, we recommend to consult your GP.
