10k gold is an alloy made up of 41.7% pure gold combined with 58.3% other metals such as silver, copper, and zinc. This blend makes it more durable, scratch-resistant, and budget-friendly than higher-karat gold, though it has a paler color and a greater chance of triggering metal allergies, particularly from nickel and copper content. 10k … Read more

Osmium isn’t magnetic, it’s paramagnetic. This means osmium is weakly attracted to a magnetic field. Osmium is paramagnetic because it has a few unpaired electrons in its d orbitals, and these unpaired  act like tiny magnets. Osmium’s paramagnetism is measured in a lab, but for all practical purposes (like handling pure osmium bullion or osmium-coated … Read more

Iridium isn’t magnetic. It’s paramagnetic. This means iridium isn’t strongly attracted to magnets but is still slightly influenced by magnetic fields. Iridium is paramagnetic due to the presence of unpaired electrons in its 5d orbitals. These unpaired electrons give rise to a magnetic moment that’s weakly attracted to an external magnetic field, a characteristic of … Read more

Black gold is a real, human-made gold alloy that doesn’t occur naturally. It’s created through electroplating yellow gold with black rhodium or ruthenium, alloying gold with metals like cobalt (75% gold, 25% cobalt), laser treatment and purposeful oxidation processes. Black gold is generally hypoallergenic and non-magnetic, except when alloyed with cobalt, which creates magnetic properties … Read more

Palladium jewelry develops patina over time. It’s a natural shift to a matte, slightly darker finish caused by microscopic scratches and skin oil contact during everyday wear. Patina is purely cosmetic and doesn’t damage the metal, though opinions on it vary, some like the vintage look, others don’t. Lower-purity alloys like palladium 500 patinate faster … Read more

Ruthenium isn’t magnetic. It’s paramagnetic. This means ruthenium isn’t strongly attracted to a magnet but is still slightly influenced by magnetic fields. Ruthenium is paramagnetic because its electronic structure contains unpaired electrons, specifically in its 4d orbitals, and these unpaired electrons are weakly attracted to external magnetic fields. So, pure ruthenium is paramagnetic, but ruthenium … Read more
