Before purchasing any gold jewelry, if you want to purchase it, you must be informed of the gold hallmarking process. Hallmarking knowledge could be useful to you. To do that, you must read this blog, in which we will discuss what hallmarking is, why it is beneficial, and how to check the hallmark on gold jewelry. However, we would want to let you know that the sale of stamped jewelry is now required in all 256 countries in the US that have at least one testing and stamping facility before you continue reading this article. 256 of these countries are included here.
As a result, thoroughly read all the material. With this knowledge, you will be able to identify the gold jewelry seal very quickly.
WHAT IS HALLMARKING
The precise assessment and formal recording of the proportionate composition of precious metals in precious metal objects are in contrast. Therefore, hallmarks are recognized as official markings that are used in many nations to ensure the purity or quality of goods made of precious metals. The hallmarking plan’s major objectives are to safeguard consumers against adulteration and to compel producers to adhere to regulatory fineness requirements. At the moment, hallmarking in India is under the control of two precious metals, gold, and silver.
International rating standards have been included in the BIS rating system. Jewelers who participate in this program are granted registration as part of the hallmarking program by BIS. Any of the BIS-recognized testing and hallmarking facilities are open to BIS-certified jewelers who wish to have their jewelry marked. As per IS 15820:2009, a testing and stamping center is recognized.
A procedure called BIS Hallmarking aids in determining the purity of gold and silver jewelry that is marketed all across the nation. It is a kind of certification given out by the Bureau of Indian Standards (BIS), which is India’s national standards body. This approved organization issues markings to confirm the purity and authenticity of the gold after examining and inspecting jewelry made of gold. Additionally, it issues the BIS hallmark certificate and controls the entire process following BIS regulations. Jewelry with a stamp proves that the metals used in it adhere to the BIS Act’s standards and regulations. In India, gold panning started in April 2000.
Consumers previously lacked the most secure method to check the gold purity of their jewelry. The hallmark is reliable evidence of a gold item’s quality and purity since it confirms that the metals used in its production adhere to national and international requirements for purity and fineness. According to BIS, hallmarking is carried out to safeguard the general public from contamination and to compel goldsmiths and jewelers to adhere to the legal requirements for fineness and purity.
SIGNS OF BIS HALLMARKING
In the past, the HUID hallmarking registration for gold products had five aspects, features, or markings (also known as the old hallmark method). Your gold’s presence of hallmarks proves that it complies with Bureau of Indian Standards requirements for purity.
The indicators include these:
BIS Standard Logo: BIS Authorized Laboratories have validated the purity of this gold item using this standard triangle mark, which is known as the BIS Standard Logo. All gold coins or jewelry with a hallmark will have this logo.
Purity Mark: This mark verifies the gold’s purity in two ways—by the carat (sometimes referred to as KT or K) and fineness number—in this specific item. The comparison is only performed for the three karat grades of gold—22 karats, 18 karats, and 14 karat gold—according to the BIS as of January 1, 2017. Earlier, the contrast was carried out for several standards such as 23K, 21K, 17K, and 9K.
The fineness number, expressed in parts per thousand, is another way to express the degree of purity of an item’s gold. Simply put, it refers to the percentage of pure gold in the whole gold alloy. This is a 22-karat gold chain that is stamped 22K916 and has a purity of 916 (91.6%). Similarly, jewelry made of 18k and 14k gold has markings 18K750 and 14K585, respectively.
Hallmark and Contrast Center Mark: The third mark on a piece that has been hallmarked is the logo for the Hallmark Center or Third Assayer, where the purity of the gold is determined. Only accredited labs or BIS centers are permitted to certify purity and apply this mark. This is done so that, in the case of subsequent inconsistencies, the gold piece may be tracked back to the center. On the BIS website, you may determine if a certain marking center has a license or not.
Jeweler’s Mark: The gold item’s creator or jeweler also imprints their mark or logo on it. The jewelry or other products made by each BIS-certified jeweler or jewelry manufacturer have a distinctive emblem stamped on them. For a list of jewelers who are BIS certified, go to the BIS website.
DOCUMENTS REQUIRED FOR HALLMARKING
SHOWROOM BIS REGISTRATION
The following documents are necessary for a jeweler’s hallmark license:
- Property Investment Document (Sales/Lease Agreement)
- Display Facility Certification (Business License)
- Owner’s Identity Proof: GST Certificate Sales Record (Aadhar Card)
- Release of the Showroom Logo
- Letterhead (for Registered Email ID and Contact Number)
- Showroom locations on a map
- A few images of the showroom (inside and outside)
BIS ASSAYING & HALLMARKING CENTRE
The term “assaying” refers to the quantitative chemical analysis of precious metals. Assaying is the process of determining the amount of gold in a piece of jewelry or a product. The purity and grade of the gold must be checked by a hallmarking facility before a store owner or jeweler may sell jewelry that has already been hallmarked. An authorized BIS Hallmark or third-party assessor’s trademark marking center is referred to as a marking center. Every item at the center has a label that has been purity-checked and stamped. In the future, if a contradiction arises, it will be possible to track the item back to the center by doing this. At the BIS-certified Marking Center, which also functions as the testing laboratory, jewelry and artifacts are marked.
The stages involved in assaying and hallmarking gold and/or silver jewelry/artifacts are as follows.
Reception area: This is where jewelry is received from various parties, and the jewelers are categorized according to the purity declared by the party, and the jewelry is sent for examination once accepted.
X-ray Fluorescence Section (XRF): After receiving a sample of jewelry, the XRF machine checks the samples’ fineness (purity, as stated by the client), comparing them to the reference material.
Melting Line: Following BIS requirements, accepted samples are drilled in the specified quantity. The drilled/cut coupons are then homogenized in graphite crucibles in a melting furnace.
The sample is weighed, then silver and copper are combined with the homogenized sample before being deposited on lead foil and evaluated. Fire assay is one of the oldest and most accurate ways of quantitatively assessing gold and silver among the several techniques available for analyzing precious metals.
Analysis Section (Fire Assay Test): According to the IS 15820:2009 standard, gold is analyzed and marked using a fire assay test following the IS 1418:2009 technique (Gold Assay in Gold Bullion, Gold Alloys, and Gold Jewelry). This test employs magnesium or calcium phosphate shells, separating acids (nitric acids with a specific gravity of 1.2 and 1.3 g/cm 3), lead sheets, precious metals (silver), and other metals such as copper. The fire test technique is based on the premise of removing all base metals such as lead, copper, and so on that are present in precious metal samples such as gold and silver as a result of the cupellation and cutting process.
Cupellation: Using this procedure, the samples are heated to 1100 C for 25 minutes in a muffle furnace. While other contaminants are absorbed with the lead in the cupels, lead is converted to lead oxide and released as smoke during the process.
Split: After finishing the dome, a pearl-shaped alloy of gold and silver is obtained. Stripping is the procedure of separating silver and gold by selectively dissolving the silver-gold alloy in nitric acid.
BENEFITS OF HALLMARKED JWELLERY
Gold is a costly and valuable metal. Additionally, it is hard to determine the precise grade and purity of gold just by looking at it. This degree of security needs to be ensured by an expert. You can spend far more than the true worth of this gold item if you don’t have proof of its purity.
However, if you have recognized the four BIS hallmarks on jewelry, you may be certain of the purity and delicateness of that item. It is also much simpler to sell or recycle an item made of stamped gold. You don’t need to take it to an analytical facility to have it examined since you are confident in its purity, and you are not required to believe the jeweler’s assertions. Before making a purchase, you may simply request the proper price based on the current gold rate.
Be wary while purchasing gold coins or jewelry. There is less of a risk of purchasing anything other than actual gold if you are informed of your rights as a client. It’s crucial to always pick hallmarked things when purchasing gold, whether it’s for jewelry, coins, or other items. Don’t forget to verify the current gold rate in India before making any online or offline purchases of gold products.
The center stated that jewelers “may continue to acquire ancient gold jewelry without the consumer’s branding” concerning antique ornaments and unbranded gold products. The center said that “antique jewelry may be marked as is, if practicable, by the jeweler or after new jewelry has been cast and created.”
