Gold – Au: Types of decorative gold plating available
The decorative use of fine gold for protecting and enhancing metal objects has enjoyed an ancient and rich tradition. Long before the invention of modern electroplating processes, craft persons would use an amalgam of mercury and powdered gold to “gild” their metal work. Numerous examples of gold gilding dating from 1500 b.c. and beyond still exists today looking as bright and vibrant as ever, seemingly untouched by the ravages of time.
Today, we utilize the electrolytic application of a gold layer to a finished object to replace traditional gilding techniques. A wide selection of gold finishes varying in colour, hardness, and plating thickness can be offered to our most quality conscious and value driven consumer.
At VinaTAB, we provide custom gold electroplating services for the individual consumer, crafts person, small manufacturers, scientific labs and restorers. Depending on your personal requirements, we can provide the most appropriate gold colour, in bright, satin or matte finishes, electroplated with the correct thickness of fine gold material.
We can electroplate onto a wide variety of nonferrous surfaces such as silver, copper, brass, bronze, aluminum, nickel, and titanium. Metals such as iron, mild steel, and most grades of stainless steel can be plated by our expert team. We do not plate onto non conductive items such as glass, plastics, wood, feathers etc.
Types of decorative gold plating available
24kt yellow – Ranging from “yellow” to “orange yellow” in colour, 24kt electroplating is very popular for it’s decorative bright finish and excellent durability. Suitable for most metal substrates, our customers utilize 24kt plating as the final finish for car emblems, gun and knife detailing, watches, writing instruments, holloware items, fine jewelry, and numerous other applications.
18kt yellow– This gold plated finish has less “yellow brass” colour than most 24kt plating. It is characterized by its more subtle yellow warmth while maintaining the depth and richness of the 24kt colours. Our customers utilize this plating finish for large scale objects to present a more understated look of fine gold.
14kt yellow – Noted for its wide range of colours tints, hues, and wear resistance, 14kt is widely regarded as the “workhorse” plating finish for the jewelry industry. Used over sterling silver as a “vermeil” finish,14kt gold plating can provide your item with years of beauty and durability.
14kt Hamilton – This 14kt plating is offered in a rich medium yellow colour that is similar in appearance to the classic “hamilton” gold watch colour favored by many watch manufacturers in the 1960’s and 70’s. This type of plating is our hardest and most durable of all the plating finishes we offer. It is very popular with our customers who are plating watches, belt buckles, and other items where extreme durability is of the highest priority.
18kt rose – Like its name suggests, this type of plating has a “rose” tint colour to its finish. Used as a final finish or as a contrast colour with yellow gold plating, 18kt rose gold plating provides a beautiful and exotic look to any item.
18kt green – A wonderful finish that can be modified from light to dark green in colour, this plating has the same durability of the yellow gold plating finishes. Selectively combined with rose and yellow gold plating, a “black hills gold” look can be restored or achieved on you fine jewelry item.

Selection of goldplating thickness
Here at VinaTAB we have the skill and capability to plate gold ranging from a thickness of 7 millionths of an inch (.175 microns) up to 300 millionths of an inch (7.5 microns). Generally the thicker the gold plating the better the durability of the plated item. We offer goldplating services for decorative and engineering applications (MIL-G-45204C). We will be happy to assist you in selecting the most appropriate gold thickness for your valued item and application.
For decorative applications, all electroplating standards are regulated by the Federal Trade Commission. Below we have provided a brief descriptive overview taken from their publication, Code of Federal Regulations, Title 16, Commercial Practices Part 23 January 1, 1999. All comments in italics are provided by us for greater clarity relative to real world plating applications.
gold flash – an electrolytic plating of not less than 10 karat minimum fineness and a thickness of less than 7 millionths of an inch or .175 microns may be only marked or described as gold flash or gold washed.
gold electroplate – electrolytic plating of fine gold with a minimum thickness of 7 millionths of an inch or .175 microns, may be marked or described as gold electroplate, gold electroplated or G.E.P.
This type of plating (14kt,18kt,24kt) is generally more yellow in colour than items that are gold flashed. With proper underplating this class of gold plating can be utilized as an economical decorative finish for surfaces which are not subject to harsh chemicals or exposure to abrasive conditions.
gold plate – a fine gold, deposited by any means with a minimum thickness of 20 millionths of an inch (.5 microns) may be marked or described as gold plate, gold plated, or G.P.
This type of plating can be utilized on items where moderate exposure to wear is expected. We encourage our clients to consider a minimum of 40 millionths of an inch (1.0 microns) of gold as an essential thickness for any plated item subject to constant handling.
heavy gold electroplate – electrolytic plating of fine gold plating with a minimum thickness of 100 millionths of an inch (2.5 microns), may be marked or described as heavy gold electroplate or heavy gold electroplated.
Based on customer feedback, we recommend this type of plating for those items which are exposed to chemicals and abrasives. For items such as watches, cuff links, or belt buckles, we suggest a minimum thickness of 2-7 microns. In most cases this will exceed the original manufacturers specifications for expected lifetime durability for even the most heavily utilized items.
vermeil – (pronounced vermay) sterling silver electrolytically plated with fine gold with a minimum thickness of 100 millionths of an inch or 2.5 microns. The existence of a base metal anti-tarnish barrier must be disclosed.
Non-silver items may not be marked “vermeil”.
