Anti-Tarnish vs. Gold-Plated (Demi-Fine) vs. Fine Jewelry: Where STUD Stands

Jewelry falls into three main categories: anti-tarnish, gold-plated (demi-fine), and fine jewelry. Each differs in durability, material, and price.

Gold-Plated Jewelry (Demi-Fine) is made by layering real gold over a base metal. It offers the look of fine jewelry without the high cost. But not all gold-plating is equal — poor-quality plating or cheap base metals can wear off quickly and cause skin irritation.

Anti-Tarnish Jewelry adds a protective layer to resist discoloration from air, sweat, and water. However, its performance depends on the base metal used. Lower-quality alloys may still react with skin, while premium bases like stainless steel or brass ensure comfort and strength.

Fine Jewelry uses solid gold mixed with alloys such as copper or nickel for durability. While it lasts for generations and retains investment value, its high price reflects the intrinsic cost of gold.

At STUD, we bring you the best of demi-fine jewelry with advanced vacuum electroplating (also called PVD / ion plating). This process bonds 18K gold layers to high-quality base metals under vacuum, making them extra durable, waterproof, and anti-tarnish. Combined with our protective coating, this means your jewelry keeps its shine, resists daily wear, and remains skin-friendly.

The price difference lies in the materials: fine jewelry = solid gold, while STUD offers demi-fine affordability with anti-tarnish durability and premium plating technology. In short, you get everyday luxury that looks premium, lasts longer, and remains budget-friendly.
