Gold vermeil tarnishes and fades over time because the underlying sterling silver base oxidizes when exposed to air, moisture, and chemicals. Pure gold doesn’t tarnish, but the porous gold layer allows sulfur to reach the silver beneath, causing discoloration. Gold vermeil isn’t waterproof and shouldn’t get wet if you can avoid it. Water seeps through … Read more
White gold is a real gold alloy created by combining yellow gold (typically 75%) with white metals like nickel, palladium, silver, or zinc. It’s commonly available in 9k, 14k, and 18k variants, with 18k being the highest commercially viable option. Unlike yellow gold, white gold doesn’t occur naturally and must be manufactured through metal alloying. … Read more
Is Palladium Jewelry Hypoallergenic? Is it Safe for People With Skin Allergies? Yes, palladium jewelry is hypoallergenic and safe for people with skin allergies, provided they’re not allergic to palladium. Palladium allergies are rare, but possible. One 5-year long study from Spain showed that out of 673 study participants, (61.6 % women and 38.4 % … Read more
Rose gold patination is a natural darkening process caused by copper oxidation in the rose gold alloy when exposed to oxygen and moisture. Rose gold patina is considered desirable as it adds vintage character and depth to rose gold jewelry rather than creating unsightly discoloration. Lower karat rose gold like 10k and 14k patinates faster … Read more
Pure platinum is safe for humans. It’s chemically inert, non-toxic, and passes through the digestive system unchanged. Platinum jewelry and bullion are safe to handle and wear. Certain platinum forms are harmful, including platinum-based chemotherapy drugs (cisplatin, carboplatin), soluble platinum salts, platinum nanoparticles, and platinum fumes, which can cause “platinosis”, a permanent allergic condition affecting … Read more
Does platinum tarnish or not? Does it oxidize, rust and corrode? No, pure platinum doesn’t tarnish, fade, dull or change color over time. It also doesn’t rust, corrode and oxidize. Platinum is a non-reactive “noble” metal that can’t tarnish and discolor. However, platinum alloyed with other metals over time develops a patina, a form of … Read more
Palladium in solid form isn’t toxic and radioactive to humans and is safely used in jewelry, dental applications, and investment bullion. However, certain palladium compounds are highly toxic. These are palladium salts (ionic forms), palladium chloride and palladium nanoparticles. Palladium jewelry and bullion are completely safe as they contain solid palladium. Pure palladium flakes can … Read more
Sterling Palladium is a modern silver alloy containing 92.5% silver, 3% palladium, and 4.5% copper, created by replacing some copper in traditional sterling silver with palladium. This substitution makes the metal harder, more durable, and more tarnish-resistant than regular sterling silver while maintaining a similar appearance. Sterling palladium is hypoallergenic for most people, though those … Read more
Gold tarnishes over time due to a combination of moisture, oxygen, sulfur compounds and other metals pure gold is alloyed with. The higher the karat of gold, the less likely it’s to tarnish. For example, 18-karat gold rings take longer to tarnish because of their higher yellow gold content. And pure 24-karat gold is non-reactive … Read more
Rose gold tarnishes due to copper oxidation when exposed to moisture and oxygen. Tarnished rose gold appears darker, muted, and more reddish-brown with a vintage patina. Lower karat rose gold tarnishes faster: 10k (41.7% gold) tarnishes quickest, followed by 14k (58.3% gold), while 18k (75% gold) tarnishes slowest due to higher pure gold content. Rose … Read more
