There are a number of different polishes the metal can take and each of your customers in turn has their own preferences.


The matte finish, for example, is a frosty, cloudy and dull finish that is given to the fine metal. The metal looks matte but still has its innate color that is never lost. This finish is very difficult to maintain as it can be scratched easily and polished with constant wear and tear.

High gloss is when the artisans design the metal to look like a mirror that is highly reflective and smooth. The metal takes on such a shiny appearance that it reflects the true colors and nature of the metal. This is a very popular finish style and also the standard style for most gold and diamond jewelry.

The satin finish is another style where the metal looks so soft it almost resembles the velvety touch of fabric. This soft look isn’t that bright, but it feels very soft while still retaining the properties of the metal. Satin-finished gold is characterized by its polished appearance, but it is not reflective. If you prefer a non-shiny polished gold effect, go for this one.

As a KPP, you can be assured of the quality of the jewelry you will receive as all of our jewelry undergoes rigorous quality checks that allow you to sell flawless jewelry safely.


Gold has been marked since ancient times and, among other things, markings have been used to indicate the purity of the metal. This tradition has been passed down through the generations and has since become almost the norm in the jewelry and bullion industry. Stamping is an integral part of the making of most of the jewelry you buy today, although you may not know it and your customers need to understand why precious metals are labeled with different quality marks. This gives every customer confidence when buying jewelry or something with precious metals. With third party verification, your customers can be confident of their purchases and don’t have to worry about anything. Quality marks clearly indicate what karatage the metal is made of, which can also help create confidence when buying.

BIS HALLMARKING In India, the BIS hallmarking system is accepted and approved by the government. You should know this BIS trademark as it will help you sell your KuberBox tested jewelry to your customers. Certified test centers can only carry out BIS markings. These centers receive extensive training by the BIS team and can then mark metals for three years in a row.

Jewelers can label their jewelry with their own quality mark, which is another widely used part of the manufacturing process. Recently, the BIS announced new standards that remove the brand’s year. Silver can also be marked in the same way and is produced in different countries around the world. Sterling silver is marked with the “Sterling” stamp of 92.5%, which indicates to customers the purity of the metal. Platinum jewelry, on the other hand, is usually marked with “Plat”, “Platinum” or “pt”. Markings.


In order to be a skilled sales assistant, you should understand the different types of quality marks that are available and sold in the market. The covering of jewelry has its own quality mark. The gold plating must always be coated with at least 10 carat gold in order to be considered gold-plated. It must also be at least half a micrometer layer on top. GP, which stands for Gold Plated, is what you will see stamped on the gold plated jewelry.

Gold plating is usually done on jewelry where the base metal is not gold. You must have heard of 1 gram jewelry. 1 gram jewelry is nothing more than a marketing gimmick where gold plated jewelry is passed on as 1 gram jewelry.


Today we cannot negate the likelihood of scammers making extra money. This is why gold testers and testing procedures have become such an important part of the retail jewelry sector. When it comes to testing the purity of the metal, there are two sub-categories: the destructive tests and the non-destructive techniques. Your customers sometimes want to sell their gold jewelry back or have their gold tested for complacency. At this point, your knowledge of testing techniques will prove invaluable as your suggestions will go a long way. The electronic gold tester is a small and compact machine with a pen-like device that detects the purity of the gold. You may have already seen it in jewelry stores as these are widely used when jewelry stores are buying back jewelry from customers. This machine gives instant results without damaging the jewelry. You also need to know that this tester is not entirely accurate as it only detects the metal on the surface. It recognizes that the gilding is gold, which would be completely wrong. The touchstone test is a relatively accurate test used to check the karatage of gold. In this process, the gold is tested for its reaction to acids. In this process, a basalt stone is first used to rub the gold on it and leave marks. This stripe marking is then confirmed with the help of two needles of the estimated caratage on either side of the stripe. Adding solutions of nitric acid or hydrochloric acid changes the color of the stripe, which thereby determines the gold caratage. Jewelers need to be careful as the piece of jewelry can be damaged if rubbed against the basalt stone. This should always be done with the consent of your customer.

Gold purity test method

The other and most accurate method is the fire test, which, due to the lengthy process, will most likely be carried out in a special facility. It is also a destructive test that destroys the entire piece of jewelry. The metal is weighed and then melted with a piece of silver at 1100 ° C. After melting, the two small balls made of silver and gold are left. These pieces are further separated with the help of a platinum-lined bowl and nitric acid. The gold separates completely from the silver, leaving behind pure metal. This is then weighed and the difference is noted. This testing process is one of the most accurate ways to test a metal. More recently, X-rays have been used to determine the purity of gold in solid gold jewelry. It does this through a process called an XRF process, in which the X-rays are used to analyze the piece of metal and then declare the composition of the metal.
