Introduction

The gold plating on jewellery gives an item the lovely appearance of gold without requiring it to be constructed entirely of pure gold. Because gold is so valuable, many individuals will not afford a solid gold piece of jewellery. The beauty of gold plating is that it allows you to imbue a piece with all of the characteristics of gold without the high expense.

People have been captivated with gold throughout history, from Ancient Egypt to Mesoamerican cultures, even though it was traditionally kept for the wealthy. Luigi Brugnatelli, an Italian chemist, created the current process of gold plating in 1805. Since then, everyone has been able to join the golden aesthetic with more inexpensive alternatives to genuine gold jewellery. If you are looking for gold plating services in Chennai, then Smart Microns is at your rescue. 

Understanding gold plating

A thin coating of gold is linked to base metal in the gold plating process. Gold and rhodium plating are two main forms of plating in the jewellery industry. Gold plating is often used to make costume jewellery look more costly or to imitate more expensive items. Unfortunately, it’s nearly hard to distinguish between costly gold jewellery and cheap gold plated imitations.

Things to consider before gold plating

Gold is hypoallergenic and does not tarnish, rust, or corrode. Many individuals prefer to coat objects that would otherwise become troublesome if exposed to circumstances that might harm the item or create an allergic reaction because of these wonderful features.

In the case of costume jewellery or jewellery composed of brass, bronze, silver, copper, nickel, or other metals, gold plating prevents the piece from colouring your finger green and, more significantly, from corroding rapidly. When brass comes into touch with human sweat, for example, it corrodes fast. Our perspiration includes salt (sodium chloride), which can discolour brass in as little as a few days after contact. This problem is avoided if the gold plating is done correctly.

Most jewellery designers and artists choose brass, bronze, silver, or copper since it is inexpensive and simple to deal with. However, selling a piece made of one of these metals at a high price is challenging because of the tarnishing difficulties we described before. When gold is added, even if it is only a thin layer of gold plating, the piece’s overall value skyrockets. For instance, we have a customer who buys Italian silver necklaces for $20 each, then gold plates them with 24 Karat gold and resells them for $200 each.

You might be wondering how much gold was used. The answer is that it’s only a few bucks. Our 24K Bright Gold Solution contains 2.5 grammes of pure gold per litre container. One gramme of fine-gold will cover around 160 square inches of space with a 1/2 micron layer of gold (0.00002″ or 20 micro-inches). For $110, you may plate roughly 160 rings or pendants with an area of around one square inch. To put it another way, gold plating a ring or pendant of this size costs around $0.68.

It’s unique to be able to electroplate objects. Few people have the knowledge or capacity to do so. With the kits, solutions, and support we provide, a whole new world of possibilities opens up. Let’s assume you produce silver pendants or rings; you could sell the same ring in various finishes. You might sell 24k, 18k, 14k, Rose Gold, Rhodium, Black Rhodium, Silver, and other precious metals. different people have different preferences when it comes to the colour they desire in a certain design. For many jewellers and painters, having this skill is invaluable.

Three primary elements influence the longevity of gold plating.

  • The sort of gold that was used.
  • The gold plate’s thickness in (millimeters).
  • Wear and tear

By its very nature, gold is a soft metal. There are two types of gold deposits: “hardened” and “soft.” Grain modifiers and hardening compounds, such as cobalt are used to harden gold. Hardened gold grain modifiers will disturb the lattice structure of gold crystals as they grow on the surface. Because of the disturbance, the crystals are considerably more densely packed, resulting in a “harder” deposit. A hardened gold’s “Knoop hardness” is 3-5 times higher than “soft” gold.

Hardened gold should always be used for plating jewellery. Soft “Pure” Gold is commonly employed in scientific plating applications, such as fuel cells. The gold must be deposited relatively thickly, be softer, withstand higher temperatures, and be free of impurities. Soft (pure) gold has a minimum purity of 99.99 per cent, whereas hardened gold has a minimum purity of 99.97 per cent. In some cases, a difference of 2% can make a big difference.

Within seconds of plating, gold becomes opaque, with a thickness of about 2-3 micro-inches. If you stop plating when the object becomes opaque, you’ll be left with a fragile covering of gold that will fade off fast – perhaps within a week or two. However, if you soak a piece in our 24K Bright Gold for 5.5 minutes, you’ll get a 40 micro-inch thick coating. A 40 micro-inch (1 micron) coating of gold plating is a rather thick layer of gold plating that will last many years, if not a lifetime if properly cared for. Our 24K Bright Gold can plate up to 100 micro-inches (2.5 microns). If not abrasively removed, this sort of thickness will last a lifetime.

Gold is prone to scratching and abrasion due to its delicate nature. As a result, we never recommend using an abrasive polish on gold. However, if an object is going to be handled often, such as a ring that is slipped on and off of a finger regularly, it is recommended that the plating be placed on the thicker end of the scale. When we receive jewellery to be plated, we always apply at least 40 micro-inches (1 micron) of plating to guarantee the consumer receives a long-lasting plate. Under US Federal Trade Commission guidelines, the minimum thickness of gold plating for jewellery products to be sold as “gold plated” in the US is 20 micro-inches.

The process of gold plating services in Chennai

  1. When you submit anything for plating, the first thing we do is evaluate it and understand what kind of metal is it? Due to their composition or the possibility of tarnishing, certain metals might be difficult to plate.
  2. Following assessment, the item is extensively polished in preparation for electroplating. Because a little lump or grainy texture will make the gold plating seem uneven and blotchy, the polisher will buff the item’s surface until it is completely smooth. Before the gold is added to base metals that are difficult to plate on their own, the jewellery is polished and given a preliminary coating of either palladium or nickel. The object is electrocleaned and washed multiple times after polishing in the following baths:
  • Water that has been distilled
  • Neutralizer
  •  Water that has been distilled
  • Dip in micron plating
  • Water that has been distilled.

     3. The gold plating procedure begins once the item has been processed and authorized. The item is submerged in a solution that contains water and “metal salt,” which contains the gold to be plated on it. An electrical charge is delivered through the liquid, causing the metals to disintegrate and the gold to chemically attach to the jewellery. Depending on how thick the plating is meant to be, the item stays immersed for a particular amount of time. While gems are typically unaffected by electroplating, costume jewellery stones are frequently glued on and may become accessible throughout the process owing to water exposure. Stones that are extremely sensitive and delicate (such as pearls) should not be plated in any way.

The cost of gold plating services in Chennai

The following factors can influence the cost of gold plating:

  1. If the base metal is unusual, like brass, it will require further treatment before being transferred to the gold plating tank. These metals will require a nickel coating, which will increase the price. 
  2. Some stones will need to be unset and reset once the item emerges from the electroplating tank since they will not resist the plating procedure. Costume jewellery presents a problem since the rhinestones are frequently glued on and loosened in the plating solution. It is necessary to factor in the expense of replacing them.
  3. The cost of the plating varies depending on the sort of gold you choose. Because there is more gold in higher-karat gold, such as 18k or 24k, it is more costly!.
  4. The more plating there is, the more expensive the work is. If you want to plate anything like a necklace or a set of earrings, keep this in mind; objects that aren’t worn on the body don’t require much gold. Plating a ring, bracelet, or watch, on the other hand, will cost more since it requires a greater micron thickness.

Metals that can be gold plated

Gold plating is possible on most metals, including nickel, brass, stainless steel, silver, and copper. On contemporary industrial metals like tungsten and titanium, gold plating is employed. The most commonly used metals are silver and copper.

Looking after gold plated jewellery

the life of the gold plated jewellery can be extended and kept bright and attractive by properly caring for it. things to consider include:

  • Solvents, oils, and cosmetics should not be used on gold-plated jewellery. After applying makeup, hairspray, and fragrances, it’s a good idea to put on your plated jewellery last. When doing housework, remove gold-plated jewellery since the chemicals in soaps, detergents, and cleaners can harm the coating.
  •  Keep your hands clean while handling gold-plated jewellery, so wash them before putting on and taking off your jewellery.
  • Chlorinated or salty water should not be used to clean gold-plated jewellery. Remove your jewellery before swimming in pools, saunas, or the sea.
  • Body oils and sweat can harm gold plating. of the gold plated To avoid this, wipe the jewellery down or clean it regularly to remove the impurities.
  • To prolong the life of your gold-plated jewellery, it is necessary to clean it on a regular basis. Use a mild liquid soap or a professional jewellery cleaning solution, together with warm water, to achieve this. Avoid using abrasive cleaners or strong chemicals. When you brush or touch plated jewellery, it might flake off, showing the metal underneath.
  • When wearing gold plated jewellery, avoid contact and tension, since this can cause the piece to wear down quickly and flake off. When you add gold plated jewellery, and they rub against one other, this might happen. It’s preferable to wear the jewellery item by itself.
