Jewellery Materials

At Krohm Studios we use various materials in our Jewellery, making each piece beautiful and unique. We believe in combining and layering different materials is the way to go. 


Here we explain the different materials so you know what you are purchasing and how best to care for it.

  • 925 sterling silver
All sterling-silver pieces are stamped with the 925 mark, indicating the purity of the metal.
  • 18K gold plated sterling silver
925 sterling silver is an excellent and high-quality material for gold-plated jewellery, as these pieces keep the shine and gilding longer. Gold-plated is a method of adding a gold layer over the sterling silver surface through an electrochemical process. Sterling silver is the most solid option you can get. It is a shiny, long-lasting, and a durable precious metal more affordable than gold. This jewelry type sometimes changes its colour over time, but there are many ways to slow down that process. Sterling silver is a silver alloy that contains: 92.5% pure silver7.5% another metal, mainly copper (this 7.5% makes this metal strong enough to make into Jewellery)
  • 18k gold vermeil plated
The thickness of the gold is a minimum of 2.5 microns, with a base of sterling silver. All gold vermeil pieces are stamped with the 925 mark to indicate the sterling silver purity. Gold Vermeil is plated with a process known as ‘electrolysis’, making the jewellery very durable.
  • 18k gold plated brass
18k gold-plated brass metal with a layer of 18ct gold in a 2 micron thickness. There’s also a layer of anti-tarnish on top. This type is more affordable that 18k gold vermeil but still durable. Brass is forged out of copper and zinc, and the resultant natural alloy is strong, durable, and its natural luster makes it one of the most unique but common metals used in jewellery. Once it’s polished, brass doesn’t tarnish, hence easy to maintain.
  • 18k gold plated stainless steel
Stainless steel is a high quality and economical metal. Unlike other metals, stainless steel does not rust or tarnish easily. It is a highly durable, allowing it to withstand the wear and tear of everyday activities. The hard metal is resistant to scratches and corrosion thanks to an invisible layer of chromium that prevents oxidation, making it a great choice for body jewellery. 18k Gold plated stainless steel is perfect for sensitive skin! You can wear necklaces and earrings swimming at the beach or pool without worrying over tarnishing, green markings, or irritation.
  • Cubic Zirconia (CZ)
Cubic zirconia is a colourless, synthetic gemstone made of the cubic crystalline form of zirconium dioxide. Coloured versions are also available. Cubic zirconia is distinct in its aesthetic qualities and physical structure because it’s lab-created. It is strong, durable, looks great, and is high quality. It is excellent value for money, offering a durable and affordable alternative to diamonds. You get the look without the price point.
  • Natural semi-precious gemstones
Natural gemstones are formed in nature with no human's interference. A mineral, stone, or organic matter that If a stone is identified as natural, it is a mineral, stone or organic matter, that has not been treated, enhanced, or altered. These gemstones are mined, cut, faceted and finally polished. A semi-precious gemstone has beauty and durability. They are also believed to have healing properties. We use a wide range of upscaled natural gemstones. Please note: Stones can vary in colour, size and shape as these are naturally formed.
