What is 18K Gold?
While 24K gold is meant for investments and 22K (916) gold is the standard for traditional Indian jewelry, 18-carat (18K) gold serves a very specific and highly popular purpose: diamond and studded jewelry.
The Purity Breakdown of 18K
18K gold consists of 18 parts pure gold and 6 parts alloy metals (such as silver, copper, nickel, or palladium). In terms of percentages, this means it is exactly 75% pure gold and 25% alloy.
Because of this exact ratio, if you look at the BIS Hallmark on an 18K piece of jewelry, it will be stamped with the fineness number 750.
Why Use 18K Instead of 22K?
The primary reason jewelers use 18K gold is durability. Pure gold is incredibly soft. If a jeweler tried to set a heavy diamond into a 22K gold ring, the prongs holding the diamond would easily bend during everyday wear, causing the diamond to fall out.
The 25% alloy in 18K gold provides the rigidity and strength necessary to firmly grip diamonds, rubies, and emeralds for a lifetime.
The Color Advantage 18K gold is also the baseline requirement for creating different gold colors. By changing the mix of the 25% alloy, jewelers can create stunning Rose Gold (by adding more copper) or White Gold (by adding palladium and rhodium plating), which are highly popular in modern engagement rings.
What is 916 Gold?
If you have ever shopped for gold jewelry in India, you have undoubtedly seen the term 916 Gold. Simply put, 916 gold is the exact same thing as 22-carat gold. It is the absolute standard for traditional jewelry making across the subcontinent.
Breaking Down the Math of 916
The number "916" refers to the fineness of the metal. Pure gold (24-carat) is considered 99.9% pure, or 999 fineness. Because pure 24K gold is incredibly soft and malleable, it cannot be used to craft durable rings, necklaces, or bangles it would simply bend out of shape.
To solve this, jewelers mix pure gold with harder alloy metals like copper, zinc, or silver. In 916 gold, the ratio is:
- 91.6% Pure Gold (22 parts)
- 8.4% Alloy Metals (2 parts)
916 Gold vs. 24K Gold
When you check the gold rate daily, you will notice that 22K (916) gold is always cheaper than 24K gold. This is simply because you are paying for 91.6% pure gold rather than 99.9% pure gold.
Investment Tip If your goal is purely financial investment, you should buy 24K (999) gold coins or bars. If you are buying gold to wear for weddings or daily use, 916 gold is the best choice, offering a perfect balance of high resale value and structural durability. Always ensure your 916 gold has a BIS Hallmark.
How much is 1 Tola of Gold?
If you speak with older generations or shop in traditional bullion markets across India, Pakistan, or the Middle East, prices are rarely quoted in grams. Instead, gold is measured in a unit called the Tola.
The Official Weight of 1 Tola
Historically dating back to the Vedic period, the Tola was standardized by the British East India Company in 1833. Based on the weight of 100 silver Rupee coins, the exact, official weight was set:
1 Tola = 11.6638 Grams
The Modern Retail Confusion: 10 Grams vs. 11.66 Grams
In 1956, India officially adopted the metric system, transitioning to grams and kilograms. To make calculations easier for everyday buyers, the jewelry industry unofficially "rounded down" the Tola.
Today, if you walk into a major showroom and ask for the price of a "1 Tola gold coin," the jeweler will almost always quote you the price for a 10-gram coin. However, in rural markets or when dealing in antique family heirlooms, a Tola may still refer to the true 11.66-gram weight.
Always Ask for Grams Because of this discrepancy, you should never base a financial transaction on the word "Tola." Always ask the jeweler to place the gold on a digital scale and multiply the exact gram weight by our live per-gram rate to ensure absolute accuracy.
What is BIS Hallmarking?
When buying gold in India, BIS Hallmarking is the ultimate guarantee of purity and consumer protection. Overseen by the Bureau of Indian Standards (BIS), hallmarking is a rigorous metallurgical assessment that certifies the exact gold content within a piece of jewelry or bullion.
The 3 Components of a Genuine Hallmark
As of recent government mandates, a genuine BIS hallmark must contain exactly three distinct laser-engraved symbols. If any of these are missing, the gold is not officially certified:
- The BIS Standard Mark: A triangular logo signifying that the assessment was done at an official Assaying & Hallmarking Centre (AHC).
- Purity Grade (Fineness): This indicates the caratage. For example, 22K916 means the item is 22-carat gold (91.6% pure), while 18K750 indicates 18-carat gold (75% pure).
- The HUID Code: The Hallmark Unique Identification (HUID) is a 6-digit alphanumeric code unique to that specific piece of jewelry.
How to Verify Your Gold You can download the official BIS Care App on your smartphone and enter the 6-digit HUID code found on your jewelry. The app will instantly display the jeweler's name, the weight of the item, and its exact purity grade, ensuring you are never cheated on resale value.
Why is it Mandatory?
Historically, local jewelers often sold 22-carat gold that actually only contained 19 or 20 carats of pure gold, melting down the buyer's investment value. The BIS hallmarking system enforces absolute transparency, standardizing the live gold price against verified metal weight across all of India.
What is Digital Gold?
In the past, buying gold meant visiting a jeweler, paying high making charges, and worrying about how to store it safely. Today, Digital Gold offers a seamless, virtual alternative that has become incredibly popular among younger investors on platforms like Paytm, Google Pay, and PhonePe.
How Digital Gold Works
When you buy Digital Gold, you are purchasing fractions of highly certified, 24K (99.9% pure) physical gold. The primary providers in India (like MMTC-PAMP, SafeGold, and Augmont) take the money you invest and store the exact equivalent weight of physical gold in fully insured, high-security vaults.
- Micro-Investing: Unlike physical coins where you must buy at least 1 or 2 grams, you can buy digital gold for as little as ₹1.
- High Liquidity: You can sell your digital gold back to the platform instantly at any time of day, receiving cash directly into your bank account based on the live market rate.
- Physical Delivery: Once you accumulate enough gold (usually 1 gram or more), you can request to have it minted into a coin and delivered securely to your doorstep.
The Hidden Spread While digital gold is convenient, it is not flawless. You still pay 3% GST on every purchase. Additionally, platforms maintain a "spread" between the buying and selling price (usually 2% to 3%) to cover storage and insurance costs. If you buy and sell immediately, you will lose a small percentage of your money.
Digital Gold vs. Sovereign Gold Bonds (SGB)
While both are paperless, they serve different purposes. Digital Gold is great for accumulating tiny amounts over time with instant liquidity. However, if you are investing large amounts of capital for a period of 5 to 8 years, a Sovereign Gold Bond is far superior, as it pays you 2.5% annual interest and has no GST or buy/sell spread.
What is a Gold ETF?
If you want to invest in gold purely for financial gain without dealing with jewelry stores, making charges, or vault security, a Gold Exchange Traded Fund (ETF) is one of the most efficient options available.
How Does a Gold ETF Work?
A Gold ETF is essentially a mutual fund that trades on the stock exchange like a regular company share. The fund's objective is to closely track the domestic physical gold price.
When you buy a unit of a Gold ETF (which usually represents 1 gram or 1/100th of a gram of gold), the asset management company takes your money and buys actual, physical gold (of 99.5% purity or higher). They store this gold in highly secure vaults. You own a "paper" representation of that physical gold.
Benefits of Gold ETFs
For modern investors tracking the daily gold rate, ETFs offer significant advantages over physical bullion:
- High Liquidity: Because they trade on the stock exchange (NSE/BSE), you can buy or sell your units instantly at the real-time market price during trading hours.
- No Making Charges: You completely avoid the heavy making and wastage charges associated with physical jewelry.
- Absolute Purity: ETF units are backed by institutional-grade gold, meaning you never have to worry about impurities or finding a trusted assayer when you want to sell.
How to Get Started Unlike Digital Gold which can be bought on payment apps, Gold ETFs require you to have a Demat account and a trading account with a registered stockbroker (like Zerodha, Upstox, or Groww). Note that while there are no making charges, ETFs do charge a minor annual expense ratio (around 0.5% to 1%) for managing the physical gold storage.
What is a Gold HUID Code?
If you have purchased gold recently, you may have noticed a tiny 6-digit code laser-engraved inside the ring or on the clasp of the chain. This is the Hallmark Unique Identification (HUID) number, and it represents the biggest anti-fraud measure in the history of the Indian jewelry market.
How HUID Works
Before HUID was introduced, BIS Hallmarking only indicated the purity (like 22K916) and the logo of the testing center. Unscrupulous jewelers could easily forge these marks.
Today, HUID functions like an Aadhaar card for your jewelry. It is a 6-digit alphanumeric code (e.g., A1B2C3) that is entirely unique to that exact piece of gold. No two pieces of jewelry in India have the same HUID.
The Ultimate Consumer Protection
The true power of the HUID code lies in its traceability. The Bureau of Indian Standards maintains a secure, centralized database of every HUID ever generated. By downloading the official BIS Care App on your phone and entering the 6-digit code, you can instantly see:
- The name and registration number of the jeweler who manufactured it.
- The name of the official Assaying & Hallmarking Centre (AHC) that tested it.
- The exact date it was hallmarked.
- The exact purity (e.g., 22-carat or 18-carat).
Mandatory by Law It is now illegal for any jeweler in India to sell gold jewelry without a 6-digit HUID code. If a jeweler attempts to sell you gold with the old 4-mark hallmark (without the alphanumeric code) or tries to tell you HUID isn't necessary, they are violating BIS regulations. You should refuse the purchase.
What is the IBJA Gold Rate?
While the MCX Gold Rate governs futures trading, the Indian Bullion and Jewellers Association (IBJA) Rate is the absolute authority for physical gold in India. Established in 1919, the IBJA publishes the daily benchmark prices that dictate physical buying and selling across the nation.
How is the IBJA Rate Calculated?
Unlike electronic stock exchanges that fluctuate by the second, the IBJA rate is a polled average. Twice a day (AM and PM), the IBJA contacts the top ten B2B bullion dealers across India. They collect their respective buy and sell quotes, eliminate the extreme highs and lows, and calculate a transparent average.
This method ensures the rate accurately reflects physical supply, demand, and local import premiums, rather than just international paper-trading speculation.
Why the IBJA Rate Matters to You
Even if you don't track it directly, the IBJA rate impacts almost every official gold transaction in India:
- Sovereign Gold Bonds (SGB): The Reserve Bank of India (RBI) uses the simple average of the closing IBJA rate for 999 purity gold over the preceding three business days to determine the exact issue price of Sovereign Gold Bonds.
- Retail Jewelry: Your local jeweler bases their daily 22K and 24K board rates on the morning IBJA publication.
- Bank Valuations: When you apply for a Gold Loan, banks value your jewelry against the current IBJA benchmarks.
The Tax Distinction The published IBJA rate is exclusively the base metal value. When you view our daily retail rates or visit a showroom, you will notice the final price is slightly higher. This is because the IBJA rate excludes the mandatory 3% GST and local making charges.
What is KDM Gold?
If you have inherited older jewelry in India, you might see a small stamp on it reading KDM. While it was once considered a sign of high quality, KDM gold represents a fascinating and ultimately banned chapter in the history of Indian jewelry making.
The Problem with Soldering Gold
To create intricate jewelry, artisans must fuse different pieces of gold together using a "solder" (a filler metal that melts at a lower temperature than the gold itself). Historically, jewelers used an alloy of gold and copper for soldering.
The problem? If a jeweler took a pure 22-carat piece of gold and soldered it with a 60% copper alloy, the overall purity of the necklace dropped to 20 or 21 carats. When customers went to sell their gold based on the daily rate, they lost money due to the impure solder.
The KDM Solution
Jewelers discovered that mixing Cadmium (abbreviated in the industry as KDM) with gold created the perfect solder. A mixture of 92% gold and 8% cadmium resulted in a solder that melted easily but maintained the overall 22-carat (91.6%) purity. Jewelry stamped with "KDM" meant the buyer was guaranteed 100% of their investment value upon resale.
Why Was KDM Gold Banned?
Despite its benefits for purity, KDM had a fatal flaw: Cadmium is highly toxic. When artisans heated the solder to join the jewelry, the cadmium released poisonous fumes. Prolonged exposure led to severe respiratory issues, kidney damage, and cancer among Indian goldsmiths.
The Modern Alternative The Bureau of Indian Standards (BIS) permanently banned the use of cadmium in jewelry making. Today, jewelers use safe zinc and copper solders in highly controlled ratios, ensuring the final piece maintains its purity. This is why you should only buy BIS Hallmarked jewelry today, rather than looking for a KDM stamp.
What are Making & Wastage Charges?
When you check the daily gold rate on our dashboard, you are looking at the raw metal value. However, when you buy a gold necklace or bangle from a showroom, the final bill is noticeably higher. This difference is primarily due to Making Charges and Wastage Charges.
Making Charges Explained
Raw gold must be melted, molded, cut, and polished into intricate designs. Making charges represent the labor cost of the artisan who crafted the jewelry. These charges are applied in two ways:
- Flat Rate (Per Gram): The jeweler charges a fixed fee (e.g., ₹400 per gram) regardless of the gold price.
- Percentage Based: The jeweler charges a percentage of the total gold value (usually between 8% to 25%). As the price of gold rises, the making charge rises with it.
What are Wastage Charges?
During the manufacturing process, cutting, soldering, and polishing cause tiny amounts of gold dust to be lost. Traditionally, jewelers passed this "wastage" cost onto the consumer, sometimes adding an extra 5% to 15% to the bill.
Today, with the advent of modern machinery and 3D printing, wastage is virtually zero. However, many traditional jewelers still combine "Making and Wastage" into a single, inflated percentage on the bill.
How to Negotiate Making charges are the only negotiable part of a gold purchase. The raw gold rate and the 3% GST are fixed by the market and government. Always ask the jeweler to separate the gold price from the making charges on the estimate. For simple, machine-made chains, you should never pay more than 5% to 8% in making charges.
What is the MCX Gold Rate?
The Multi Commodity Exchange of India (MCX) is India's largest commodity derivatives exchange. When financial news outlets talk about gold going up or down, they are usually referring to the MCX Gold Rate the live, electronic trading price of gold futures contracts.
Retail Market vs. MCX Market
A common source of confusion for buyers is checking the MCX price online and then going to a local jeweler, only to find the retail price is significantly higher. It is crucial to understand that you cannot buy physical jewelry at the exact MCX rate.
The MCX price represents "paper gold" traded in massive, bulk quantities between institutional investors, banks, and large bullion dealers. It serves as the baseline foundation for physical pricing, but lacks retail overhead.
How MCX Affects Your Local Jeweler
To calculate the final retail gold rate you pay in a showroom, the market takes the baseline MCX price and adds:
- Physical Delivery Premiums: The cost to securely transport and insure physical bullion.
- Local Association Margins: Regional jewelry associations add minor margins based on local supply and demand.
- Taxes & Craftsmanship: The mandatory 3% GST and the jeweler's making charges are applied at the point of sale.
Tracking the Trend While you cannot buy at the MCX price, tracking it is the best way to predict retail price movements. If the MCX gold futures open 2% higher in the morning, you can guarantee that your local city's 22K and 24K retail rates will spike proportionately later that day.
