Jewellery is an ornament forged with different metals, precious stones, gems, and minerals. In this article, we shall discuss the magnetic properties of different types of jewelry.
Jewellery can be magnetic or nonmagnetic depending upon the type of metal/matter used. Most jewellery is made using metals that are nonmagnetic or diamagnetic metals to last for a long period. Some metals are alloyed with other metals to improve corrosion resistance.
Some jewellery gets corroded easily while some last for a long and it depends upon the magnetic properties of the material used. Magnetic jewellery is used for magnetic therapies. We shall discuss the magnetic response of different jewellery further in this article.
Is gold plated jewellery magnetic?
Most of the jewellery made up of copper or silver is plated with gold. Let us see whether gold-plated jewellery is magnetic or not.
Gold-plated jewellery is not magnetic because it is diamagnetic. Gold has half filled stable 6s orbital giving it diamagnetic characteristics. Hence, gold has a good corrosion resistance property, which is why it is used to coat paramagnetic and ferromagnetic metals to improve their lifespan.
Is stainless steel jewellery magnetic?
Stainless steel jewellery is created using an alloy of iron and also contains 11% of chromium. Let us understand the magnetic behavior of stainless steel jewellery.
Stainless steel jewellery is magnetic and shows paramagnetic behavior. The paramagnetic behavior is due to the presence of iron and chromium alloy. Iron is ferromagnetic, while chromium is anti-ferromagnetic. Fe has four unpaired parallel electrons, while Cr has four anti-parallel electrons.
Are piercings magnetic?
Piercing jewellery is mostly a gold alloy of 18 karats composed of a copper and silver mixture. Let us discuss whether piercing jewellery is magnetic or nonmagnetic.
Piercing jewellery is not magnetic and does not show any interaction with a magnet or magnetic field. Gold is diamagnetic, copper is paramagnetic, and silver is also diamagnetic. Since Piercing jewellery composes of 75% of gold, it gives it diamagnetic characteristics and hence does not corrode.
Is costume jewellery magnetic?
Costume jewellery comprises gemstones, minerals, and stones, with inexpensive materials. Let us ponder on whether costume jewellery is magnetic or not.
Costume jewellery is magnetic or nonmagnetic based on the type of metal and gemstones used. Every gemstone shows different magnetic responses depending on the structure, bonding, and chemical compositions. Costume jewellery is not long-lasting, has low resistance properties, and can rust easily.
The jewellery made up of topaz, diamond, zircon, amethyst, quartz, and smoky quartz are nonmagnetic, while citrines, brown and blue topaz, calcite, glass, and aquamarine are weakly magnetic, and almandine garnet, peridot is dragged by a magnetic field.
Is bead jewellery magnetic?
Beads are made up of glass, metal, gemstones, and plastics. Let us discuss whether beads used in jewellery are magnetic or not.
Bead jewellery can be magnetic or nonmagnetic depending upon the types of bead matter used. The plastic is nonmagnetic, glass can be weakly magnetic, and the metals and gemstones used in beads are mostly diamagnetic. It depends upon the types of alloy and gemstone used.
Conclusion
Many pieces of jewellery are not magnetic because they are produced with diamagnetic material and alloys to keep them free from corrosion. A few pieces of jewellery are made of magnetic stones and materials attracted by the magnets. There is even jewellery made up of magnets.

Hi, I’m Akshita Mapari. I have done M.Sc. in Physics. I have worked on projects like Numerical modeling of winds and waves during cyclone, Physics of toys and mechanized thrill machines in amusement park based on Classical Mechanics. I have pursued a course on Arduino and have accomplished some mini projects on Arduino UNO. I always like to explore new zones in the field of science. I personally believe that learning is more enthusiastic when learnt with creativity. Apart from this, I like to read, travel, strumming on guitar, identifying rocks and strata, photography and playing chess.
