PVD Gold Plated Jewelry

The durability and longevity of PVD-coated jewelry can vary depending on several factors, including the quality of the coating, the thickness of the coating, and the type of jewelry. Normally, PVD coating on stainless steel jewelry can last at least 2 years.

• Quality of the Coating: The technique of the coating plays a significant role in determining how long the jewelry will last. Compared to traditional electroplating, PVD coatings applied using proper techniques tend to be more durable and longer-lasting, leading to high-quality jewelry.
• Thickness of the Coating: The thickness of the PVD coating can also influence its longevity. Thicker coatings may be more durable but can affect the jewelry’s appearance. Common PVD coating thickness is 0.03 micron. Some quality and long-lasting coating jewelry can reach up to 0.08 micron.
• Type of Jewelry: The lasting times can be various depending on the type of jewelry. And the ring can last the least time among all the jewelry, for it experiences the most frequent friction and wear due to hand movements, contact with hard objects, and everyday usage, gradually causing the coating to wear off.

• 24K Gold Plating Jewelry: 24-karat gold plating is pure gold, giving it a deep, luxurious yellow hue. It’s often more expensive due to its high gold content and the need for careful handling. However, it can be too soft for some jewelry applications and may be more prone to scratching and wear over time.
• 18K Gold Plating Jewelry: 18-karat gold plating contains 75% gold, offering a warm, slightly less intense yellow color compared to 24K. It offers a good compromise between color richness and resistance to wear, making it suitable for many jewelry pieces.
• 14K Gold Plating Jewelry: 14-karat gold plating contains 58.3% gold, providing a more subtle, less intense yellow color compared to 18K and 24K. For its good durability and more affordable option, it’s a common and popular choice in gold-plated jewelry.
• 10K Gold Plating Jewelry: 10-karat gold plating contains 41.7% gold and has the lightest yellow hue among these options. However, it is the most budget-friendly and durable option because of the higher proportion of other metals, making it accessible to a wider range of customers.

Inspections are crucial for maintaining jewelry quality and customer satisfaction. Here are the four key tests PVD-coated jewelry at Kesheen will go through to guarantee its durability.

• Electroplating Thickness: Reach the standard from 0.03 to 0.08 microns you require for your jewelry and ensure that the surface is even and thick enough to cover the color of the base stainless steel.
• Roller Abrasion Resistance: The process is to mimic the daily abrasion in an extreme circumstance. For qualified jewelry, the color can only fade a little, but it still maintains the plated layer and does not show the base material.
• Potassium Sulfide Anti-Oxidation Discoloration: After immersing the jewelry in a 5% potassium sulfide solution at room temperature for 30 minutes, the jewelry should not exhibit any discoloration or blackening when removed.
• Adhesion between Finishes and Substrate: Make horizontal and vertical incisions or scratches on the jewelry’s surface, and use 3M adhesive tape to attach the jewelry. The finishes that have been divided should not experience any peeling of the electroplated layer.

PVD coating uses a physical reaction to create a variety of colors and finishes by vaporizing different metals, nitrides, and oxides. It is an environmentally responsible approach that stays away from hazardous chemicals and heavy metals and is renowned for its outstanding durability and resistance to wear, corrosion, and tarnishing.

As for the electroplating process, which is an electrochemical method, jewelry is immersed in a solution containing metal ions, and a direct current induces the metal ions to attach. There are only several metals, and colored types can be electroplated, such as nickel, rhodium, silver, and gold. It’s less resilient and prone to tarnishing in a short time. What is more, it may include toxic chemicals and heavy metals that, if improperly managed, pose environmental dangers.
